welp I'm doing a flatten-and-reinstall in the next day or two so whatever. I'll just leave my .inos in the backup folder and see what happens with a clean install

pastel panther Oct 24, 2017, 6:11 AM

#

If you can come by during the day (US time zones), there will be more people with more relevant CP experience than me around

Because Code + Community truly does equal #CircuitPython. ❤️ @adafruit

lofty topaz Oct 24, 2017, 1:50 PM

#

@formal plover I did a search on Amazon in my Kindle Books for CircuitPython and got zero results. Looks like a niche to me. Who will be the first? Simon Monk perhaps? Will be waiting impatiently. ><>

formal plover Oct 24, 2017, 1:52 PM

#

@lofty topaz it'll probably be a good while till there's a book out on it. Maybe a make magazine special for it first.

lofty topaz Oct 24, 2017, 1:53 PM

#

Hope so. Just renewed my Make mag subscription. Such a cool publication.

formal plover Oct 24, 2017, 1:54 PM

#

There's a make "getting started with the Trinket". Original trinket of course

#

@lofty topaz agreed. Make magazine is awesome. I snag bulk copies from humble bundle

lofty topaz Oct 24, 2017, 1:55 PM

#

Yup, by Mike Barela I believe. Good book.

#

In fact, I'm recieving a Trinket M0 today. Came free with my order.

formal plover Oct 24, 2017, 1:56 PM

#

Woot woot! Love the freebies.

lofty topaz Oct 24, 2017, 1:57 PM

#

No kiddin' eh?

#

Getting a free Gemma and a CPX also. How cool is that?

formal plover Oct 24, 2017, 1:58 PM

#

I can't even put in words how cool it is.

lofty topaz Oct 24, 2017, 1:59 PM

#

I know, just when I needed to replenish my workshop with a rather large order, Adafruit comes along and provides this program for getting all this free stuff. I was very happy indeed.

#

My package arrives today. It's Christmas time in the fall. Gotta love it.

formal plover Oct 24, 2017, 2:01 PM

#

That's awesome @lofty topaz

#

A lot of us that hang out here have the Trinket M0, so if you have any questions there will be plenty of help available

lofty topaz Oct 24, 2017, 2:08 PM

#

@formal plover Oh, I know, some of you guys and gals seem to live in here. I would if I could but I can't. Nice to know though that whenever I need help, it's just a click away. Sort of like an online "Hit F1". Remember that?

umbral dagger Oct 24, 2017, 2:16 PM

#

@lofty topaz There's at least one MicroPython book.

#

@lofty topaz Mostly PyBoard focussed, with a chapter on the ESP8266

lofty topaz Oct 24, 2017, 2:19 PM

#

@umbral dagger Yup, Got it. Use it. Got the pyBoard, OpenMV M7 uses it as well. Very well done.
Programming with MicroPython Embedded Programming with Microcontrollers and Python Nicholas H. Tollervey

umbral dagger Oct 24, 2017, 2:21 PM

#

@lofty topaz No.. I was thinkign of (and have) "Python for for Microcontrollers" by Donal Norris (McGraw Hill)

lofty topaz Oct 24, 2017, 2:21 PM

#

There's also a "Getting Started..."

#

Yup, that's it. got it to

#

Also - OpenMV Development Workshop by Agus Kurniawan. Very well done.

umbral dagger Oct 24, 2017, 2:28 PM

#

@lofty topaz As for discord, I've been just leaving it open in this channel and check in occasionally.

#

@lofty topaz Then again, I work from home 100% and am pretty much self-directed.

lofty topaz Oct 24, 2017, 2:31 PM

#

@umbral dagger See, I pop in and pop out from the taskbar icon. Otherwise, the window would be open on one of the three screens and I would be reading things all the time. The place is great, but you can get caught up in it as well. I've learned that lesson long ago.

umbral dagger Oct 24, 2017, 2:31 PM

#

@lofty topaz Yup... which is one reason I'm limited twitter usage to my tablet.

lofty topaz Oct 24, 2017, 2:31 PM

#

I'm at home 100% as well. Just that I'm retired.

#

I'll tell ya what tho, I love Arduino. And Adafruit makes it so much fun.

umbral dagger Oct 24, 2017, 2:34 PM

#

@lofty topaz What is it that you love about Arduino? (don't worry, I do too)

lofty topaz Oct 24, 2017, 2:34 PM

#

Can you imagine having Adafruit back in 1977 when I was build Z80 micros for work?

#

@umbral dagger What I love about Arduino is the same thing I love about Circuit Playground, no OS.

umbral dagger Oct 24, 2017, 2:36 PM

#

@lofty topaz Yeah, seriously. I did alot of business with Jameco back then. And there was a place about an hour from where I lived. No online ordering or next day delivery. How did we manage?

lofty topaz Oct 24, 2017, 2:37 PM

#

@umbral dagger Purchasing agents.

umbral dagger Oct 24, 2017, 2:37 PM

#

@lofty topaz That does streamline many things. Though, I am looking at some sort of RTOS for my next gen (ARM Cortes-M4 based) smarthome sensor node. FreeRTOS looks capable yet fairly minimal and unobtrusive.

#

@lofty topaz I didn't have the luxery of a purchasing agent. My work was either hobby or solo contracts.

#

@lofty topaz We've wander off topic I fear.

lofty topaz Oct 24, 2017, 2:39 PM

#

@umbral dagger Zenith gave me $25,000/year for parts and test equipment. I was 20 years old.

umbral dagger Oct 24, 2017, 2:39 PM

#

@lofty topaz Sweet deal.

lofty topaz Oct 24, 2017, 2:39 PM

#

@umbral dagger My Z80 controlled machines produced products that saved them 40 million a year. They liked me a lot.

umbral dagger Oct 24, 2017, 2:40 PM

#

@lofty topaz But re: no OS. I feel CP gives you just enough (REPL + flash drive). I'd argue that is a basic OS. You have a flash file system. Between that ease of use and the Python language it's very approachable.

lofty topaz Oct 24, 2017, 2:41 PM

#

It was so sweet, I turned down Bill Gates when he offered me a job with his new startup in Seattle.

umbral dagger Oct 24, 2017, 2:41 PM

#

@lofty topaz Good on you... you got to keep your soul.

lofty topaz Oct 24, 2017, 2:41 PM

#

I know, but......

umbral dagger Oct 24, 2017, 2:42 PM

#

@lofty topaz Investing would have been smart 😃

lofty topaz Oct 24, 2017, 2:43 PM

#

A house wife, 3 kids, 2 cars, mortage, bills, food, clothing, education, yeah, I should have invested.

#

But 10 cents don't buy much stock.

#

😃

#

However, I did invent a way to squeeze blood out of a turnip.

umbral dagger Oct 24, 2017, 2:47 PM

#

@lofty topaz You should have worked for the Red Cross.

lofty topaz Oct 24, 2017, 2:48 PM

#

@umbral dagger It was more of a process I call "Don't Ask for Permission, just Beg for Forgiveness".
Works every time. 😃

umbral dagger Oct 24, 2017, 2:48 PM

#

@lofty topaz Yes, and if you're good/lucky you end up not having to beg very often.

lofty topaz Oct 24, 2017, 2:48 PM

#

BINGO!

#

Now I just need to intercept that delivery truck so she doesn't see it.

#

I got a boat load of parts from Adafruit coming today.

#

Hey @umbral dagger , you ever use those wireless chargers? I'm getting that Qi stuff and going to play with it.

umbral dagger Oct 24, 2017, 2:53 PM

#

@lofty topaz I have not.

lofty topaz Oct 24, 2017, 2:54 PM

#

Just wondering. New to me. Good learning oppurtunity. Wanna see how they do it and how good they are. Where's the technology at and so forth. Gotta love hacking.

umbral dagger Oct 24, 2017, 2:55 PM

#

@lofty topaz I expect it's basically a transformer: incoming in the base, outgoing in the device.

lofty topaz Oct 24, 2017, 2:57 PM

#

@umbral dagger Right, but what is the frequency. What levels are they using. My curiosity needs to know. That's all.

umbral dagger Oct 24, 2017, 2:58 PM

#

@lofty topaz Sounds like your findings woudl make for an interesting read. Especially if there were information on how to abuse it 😃

lofty topaz Oct 24, 2017, 2:59 PM

#

@umbral dagger Well, that's true, but I was thinking more along the lines of shaping the coils for maximum energy transfer. They look like they're just flat wound. Wonder what the tesla levels are?

slender iron Oct 24, 2017, 3:57 PM

#

@lofty topaz ZThe Nicholas Tollervey book talks about CircuitPython on the CircuitPlayground Express

lofty topaz Oct 24, 2017, 4:02 PM

#

@slender iron Your absolutely correct. Just looked. Nice piece of work to. Thanks eh... ><>

slender iron Oct 24, 2017, 4:03 PM

#

no problem! @plucky flint would be happy to hear you are reading it

#

@timber lion thanks for adding the high side/low side thermistor support

tidal kiln Oct 24, 2017, 4:17 PM

#

@slender iron sry, was afk 2nd half of yesterday

#

eyes on request was for:
https://github.com/caternuson/CircuitPython_ADS1x15/tree/multi

GitHub

caternuson/CircuitPython_ADS1x15

CircuitPython_ADS1x15 - CircuitPython driver for ADS1015 / ADS1115 ADCs

slender iron Oct 24, 2017, 4:17 PM

#

no problem @tidal kiln

#

ah ok

#

will look now

tidal kiln Oct 24, 2017, 4:18 PM

#

uses one of your earlier suggestions and breaks into multiple files

#

to deal with the various modes: single, differential, etc.

slender iron Oct 24, 2017, 4:19 PM

#

👍

tidal kiln Oct 24, 2017, 4:20 PM

#

only the ADS1115 is implemented, ADS1015 is empty but would be same

slender iron Oct 24, 2017, 4:22 PM

#

api looks good to me

#

the differential and single ended read code should be pushed down so itys only loaded when needed

tidal kiln Oct 24, 2017, 4:24 PM

#

refactor out of the ADS1x15 class?

slender iron Oct 24, 2017, 4:24 PM

#

another way to say it is to split it

#

yeah

tidal kiln Oct 24, 2017, 4:25 PM

#

'loaded' = when an import is done? to conserve limited space?

slender iron Oct 24, 2017, 4:25 PM

#

yup

#

you can have a shared parent for each mode

tidal kiln Oct 24, 2017, 4:26 PM

#

that's what the ADS1x15 is currently

slender iron Oct 24, 2017, 4:27 PM

#

right, so keep that to store the _read code thats completely shared

formal plover Oct 24, 2017, 4:28 PM

#

My M4 arrived btw everyone!

slender iron Oct 24, 2017, 4:28 PM

#

yay @formal plover

tidal kiln Oct 24, 2017, 4:29 PM

#

so same setup, just need to refactor some stuff out of the current ADS1x15?

formal plover Oct 24, 2017, 4:29 PM

#

Totally going to post it with #leeks on Instagram later Lolololol

slender iron Oct 24, 2017, 4:30 PM

#

yeah, think so @tidal kiln

#

in ADC_Channel you don't need _value and _volts, you can just return them directly

tidal kiln Oct 24, 2017, 4:32 PM

#

thanks. yeah. figured that. a detail i was still learning / uncertain about with the whole @ property thing.

slender iron Oct 24, 2017, 4:32 PM

#

😃

#

another thing that migh tbe nice is to make the getitem for differential take a tuple instead of index

#

so (0, 1) instead of 0

tidal kiln Oct 24, 2017, 4:33 PM

#

meaning dif of chan 0 and chan 1?

slender iron Oct 24, 2017, 4:36 PM

#

exactly

tidal kiln Oct 24, 2017, 4:36 PM

#

it doesn't work that way, there are only preset channels, so it's more like a mode than an arbitrary setup

#

0 = Channel 0 minus channel 1
1 = Channel 0 minus channel 3
2 = Channel 1 minus channel 3
3 = Channel 2 minus channel 3

#

and that's what you're passing in

slender iron Oct 24, 2017, 4:39 PM

#

right, thats what you give the hardware but should the user have to do that?

#

you can throw an error for an invalid combination

tidal kiln Oct 24, 2017, 4:40 PM

#

yeah, could do that. so only valid options would be (0,1), (0,3), (1,3), (2,3)

slender iron Oct 24, 2017, 4:41 PM

#

right

#

I think thats clearer for the user. what do you think?

tidal kiln Oct 24, 2017, 4:42 PM

#

people wouldn't read manual, think it would allow for any combination, but most combos they try would throw an error

#

could be frustrating

#

esp. since the modes it does support are kind of weird

#

0 and 3 make sense

dif_chan = adc[(0,1)]

@lofty topaz This brand new book includes CPX with CircuitPython as one of the main examples of using MicroPython/CircuitPython. @plucky flint, the author has been in the chat. https://www.amazon.com/Programming-MicroPython-Embedded-Microcontrollers-Python/dp/1491972734

#

He works on the mu Python editor as well.

@slender iron @tulip sleet @lofty topaz Just bought it. Looks good.

lofty topaz Oct 24, 2017, 4:53 PM

#

I am looking for the Exclusive "CPX" book to come out. They will come. Look at how fast Micro:bit sprang up books and pdf's, it was great. MicroPython and CircuitPython put Python in the hands of the embedded developer. aka Hacker/Maker.

#

And I will defend my opinion that there is no OS. It's more of an Operating Environment. I know it has file access and who knows, some day a shield will have a hard-drive. 'em, Lot's of SD's.

#

But Arduino and CPX are perfect embedded platforms for ages 1 - adult. And I use that term adult loosely. 😃

#

Sorry Raspberry Pi, but it's time to move over, just a little anyways.

[adafruit/circuitpython] New comment on pull request #362: Add pycodestyle checking to Travis

Try doing pip3 install pycodestyle here. I don't think the language setting isn't having influence over this because only one language (c in this case) can be selected at a time.

#

@tulip sleet I'm gonna start working on the nrf52 merge today so ktown can start hacking on it in master

tulip sleet Oct 24, 2017, 5:06 PM

#

@slender iron sounds good; i have some leads on the USB MSC problem. When things are bad system logs are filled with

Oct 23 21:22:04 salmonx kernel: [28976.968206] sd 6:0:0:1: [sdd] Sense Key : Illegal Request [current] 
Oct 23 21:22:04 salmonx kernel: [28976.968207] sd 6:0:0:1: [sdd] Add. Sense: Invalid command operation code```

so it's something in the way the MSC device is responding to certain requests, it appears

formal plover Oct 24, 2017, 5:07 PM

#

@lofty topaz I use my Raspberry Pi to work on my CircuitPython boards.

#

Best of both worlds.

And Chromebook depending on what I'm doing.

thanks @tidal kiln

umbral dagger Oct 24, 2017, 5:40 PM

#

@lofty topaz No OS the way the original Smalltalk and Lisp systems had no OS. They were the OS.

#

OS = something that lets you load code and execute it. And provide I/O capabilities.

lofty topaz Oct 24, 2017, 5:44 PM

#

@umbral dagger Well, sort of. Do you remember the old "Monitor" programs? Once the bootloader set itself up, the Monitor would take over allowing you to do just what you said. Load code from somewhere or display memory or set I/O bits etc.

#

All controlled from a teletype over RS 232

lofty topaz Oct 24, 2017, 5:45 PM

#

@umbral dagger Nice.

umbral dagger Oct 24, 2017, 5:46 PM

#

@lofty topaz Still an OS. Not a Disk OS.

#

Although with the USB drive thingy...

#

@lofty topaz “Just Enough OS” 😉

#

@lofty topaz I’m using a very liberal definition of “OS”

lofty topaz Oct 24, 2017, 5:48 PM

#

@umbral dagger Oh, well, I suppose so, but normally an OS will wait for you to tell it what to run, not Load-n-Go like Arduino and CPX. But I understand your point and it's well taken. I just think there should be a distinction between these type systems before we go much further into the future. 😃

umbral dagger Oct 24, 2017, 5:48 PM

#

@lofty topaz A “runtime”?

lofty topaz Oct 24, 2017, 5:49 PM

#

Ah ah ah ah ... wow, haven't used that term in soooooo long. But, yup, a runtime.... ><>

umbral dagger Oct 24, 2017, 5:50 PM

#

@lofty topaz Loader, executer, I/O libraries, REPL.

lofty topaz Oct 24, 2017, 5:52 PM

#

@umbral dagger That's right, a very understandable way to interact with an interpretive environment. I keep getting asked by young people what the difference is between Arduino and Raspberry Pi. I say no OS and they look at me with a confused face. That worries me.

pastel panther Oct 24, 2017, 5:52 PM

#

Why would that worry you?

lofty topaz Oct 24, 2017, 5:52 PM

#

Or I say "headless".

#

@pastel panther What's the difference between a bicycle and a car? They need to know the difference when it's major.

#

Just my opinion.

pastel panther Oct 24, 2017, 5:55 PM

#

@lofty topaz I suppose it depends on your definition of "needs to". Expectations should vary depending on the person and the position. Also ignorance shouldn't be a problem unless it's willful

lofty topaz Oct 24, 2017, 5:56 PM

#

@pastel panther OH, absolutely, my concern is for those interested in the fields of our realm. Not everybody.

pastel panther Oct 24, 2017, 5:56 PM

@solar whale Right but is that how it works regardless? Or can I have simultaneous debug and non debug builds?

slender iron Oct 24, 2017, 6:06 PM

the m0 must be slow enough that its less likely that we change the memory befor eit gets output on usb

If you have your own fork you’ll have to set an upstream remote and fetch/pull that.

@idle owl hmm... boot & circuitpy drive showing up consistantly, repl access consistantly, line editing in the repl (up down, back forth, editing), consistant/correct repeated dir of a module.

#

I was having trouble with all that last night.

idle owl Oct 24, 2017, 6:47 PM

#

Once I renamed my code.py again, it went immediately to the REPL. Still doesn't play nice with a code.py running though. Otherwise, yeah, this nailed all of it. I'll try flashing it a few more times to see if it consistently comes up

umbral dagger Oct 24, 2017, 6:47 PM

If len (same as output_len here) > 64 AND the input buffer is not aligned on a 4-byte boundary, then I think the memcpy will write past the end of cdc_output_buffer, which is only 64 bytes long.

pastel panther Oct 24, 2017, 7:15 PM

#

Stupid question but is mass storage related to usbmodem stuff?

tulip sleet Oct 24, 2017, 7:16 PM

#

3.0 is presenting two mass storage devices at once (may be a mistake), and the second one does not behave well. That could cause various issues with stuff like the terminal. On Linux, it makes the daemon process running the USB stuff act up.

#

Still looking at this.

#

[adafruit/circuitpython] New comment on pull request #366: atmel\-samd: Use our own CDC output cache because the internal

but if the buffer is "misaligned" don't you have to do this on every transmission? As Dan pointed out, if buffer length is > 64 and misaligned it will send it all on the first pass.

64 is a repeated magic number. Is it the size of the internal cache? Are you willing to static const or #define it or use sizeof(cdc_output_buffer) ?

first micro python and then circuitpython, yes.

tulip sleet Oct 24, 2017, 9:07 PM

Is the machine a desktop that you could add another internal drive to? Do you have a spare drive?

solar whale Oct 24, 2017, 9:07 PM

@tulip sleet yes

tulip sleet Oct 24, 2017, 9:08 PM

@solar whale I'm working on that - it's presenting two drives but there's really only one.
Make this patch (one line change):

diff --git a/atmel-samd/usb.c b/atmel-samd/usb.c
index 4f7080dc8..fb7d77ec0 100644
--- a/atmel-samd/usb.c

+    //    mscdf_init(1);

#

just make mscdf_init(1) be mscdf_init(0). That will get rid of the bad drive. It still isn't working right (CIRCUITPY disappears after 30 seconds sometimes), but it gets rid of the voluminous errors.

solar whale Oct 24, 2017, 9:10 PM

#

I'll give it a try

hollow tartan Oct 24, 2017, 9:10 PM

#

my gut feeling about dual drives in one desktop case, is that harmonics are going to byte you.

#

@tulip sleet thanks for the inputs, I will work on Vagrant for another day or two to see for myself.

tulip sleet Oct 24, 2017, 9:12 PM

#

alternatively just install plain VirtualBox or VMWare Workstation Player (free) and then install Ubuntu as a regular VM.

tidal kiln Oct 24, 2017, 9:17 PM

#

@idle owl cool. thanks for documenting the discussion.

solar whale Oct 24, 2017, 9:17 PM

#

@tulip sleet with that change - I just keep going back to METROM4BOOT

idle owl Oct 24, 2017, 9:18 PM

#

@tidal kiln Sure! I had written some of it down and it made sense to include it since if it gets picked up again, all the same ideas and opinions will still be there for it.

tulip sleet Oct 24, 2017, 9:18 PM

#

@solar whale I am testing on M0 Metro, not M4. You just changed the 1 to a 0, right?

umbral dagger Oct 24, 2017, 9:19 PM

#

@tulip sleet That lets me bring up METROM4BOOT, flash the new build onto it, then it comes up with CIRCUITPY. Hoever screen just gives nothing. Exiting out takes a while (C-a k y... wait)

tidal kiln Oct 24, 2017, 9:19 PM

#

@idle owl yes. good. also because there's a good chance i'll re-think of this idea and ask for it again in a few months.

solar whale Oct 24, 2017, 9:19 PM

#

@tulip sleet yes - but now it boot on my MAc, bit does not mount CIRCUITPY

idle owl Oct 24, 2017, 9:19 PM

#

@tidal kiln lol. Understood. I do the same thing 😃

solar whale Oct 24, 2017, 9:20 PM

#

and it dies after a few minutes... 😦

tulip sleet Oct 24, 2017, 9:20 PM

#

@solar whale you included this afternoon's CDC fixes from Scott, right?

solar whale Oct 24, 2017, 9:20 PM

#

yes - did git pull

umbral dagger Oct 24, 2017, 9:21 PM

#

@tulip sleet Also, I can edit main.py on CIRCUITPY. Saving updates it and stops the running code, but doesn't reload. Resetting starts it running (and CUIRCUITPY once again is there).

#

@tulip sleet This is after pulling in the latest changes in master, along with applying you 1->0 patch locally.

solar whale Oct 24, 2017, 9:24 PM

#

@tulip sleet it is working now on Linux ! but Mac is not happy....

umbral dagger Oct 24, 2017, 9:25 PM

#

@solar whale @tulip sleet I'm on Linux as well Ubuntu 17.04

solar whale Oct 24, 2017, 9:26 PM

#

@tulip sleet but on;ly once 😉 after disconnect it hangs

tulip sleet Oct 24, 2017, 9:26 PM

#

@solar whale yes, this is just fixing one problem (maybe). There were two raw devices presented (sg3 and sg4), but one was always reporting "not ready", which seemed to make the driver ask again and again, "ready yet? ready yet? ready yet?" It was in there to eventually allow access to CIRCUITPY and an SD card, but we can take out the latter for now.

#

it's still pretty unhappy

#

If you plug it into Linux you'll see it appear, and fail to answer some questions (is write enabled?, etc.). Then every 30 seconds the driver resets it and goes through the initial dialog again. I'm comparing the USB traffic with 2.1.

#

I mean if you tail kern.log or syslog

solar whale Oct 24, 2017, 9:35 PM

#

sigh - reverted back to master for now - at least it is somewhot well behaved on the MAc.

#

or it was - not not working at all....

idle owl Oct 24, 2017, 9:40 PM

#

@solar whale I had to reset it a bunch to get it to show up.

#

@solar whale And I had to rename main.py/code.py to anything else to get the REPL to work. It'll make the serial connection, but I can't get to the REPL without renaming that.

solar whale Oct 24, 2017, 9:41 PM

#

got it back - unplugged USB and replugged

umbral dagger Oct 24, 2017, 9:43 PM

#

@tulip sleet Hmm... I didn't notice this before. When I edit/save main.py on CIRCUITPY not only does the previous version stop running, but if I have CIRCUITPY open in a file browser it sits spinning "loading" trying to refresh it.

tulip sleet Oct 24, 2017, 9:43 PM

#

@umbral dagger this is 3.0, right?

umbral dagger Oct 24, 2017, 9:44 PM

but lost it again....

umbral dagger Oct 24, 2017, 9:44 PM

#

@tulip sleet Yes, latest master (plus your patch to only open one device)

#

(yes, my linux box is rohan.. open grassy plains, majestic snow capped mountains... my Mac is morder....)

tulip sleet Oct 24, 2017, 9:45 PM

#

@umbral dagger I see that too. Don't know why. I'm reading the ASF4 driver code now. Scott's code seems to be doing the right thing with respect to it, but the low-level code may be buggy.

formal plover Oct 24, 2017, 9:46 PM

#

Do we have like a step 123 for getting the M4 up to testing level?

idle owl Oct 24, 2017, 9:46 PM

#

Kind of?

#

Install the J-Link software first.

umbral dagger Oct 24, 2017, 9:47 PM

#

@umbral dagger yeah same here

idle owl Oct 24, 2017, 9:48 PM

#

@slender iron @tulip sleet Do you have an updated version of the uf2 installer or is the one from 22 October stil valid

solar whale Oct 24, 2017, 9:48 PM

#

OK - Mac is happy again with 3.0 Master build - blinky is running CIRCUITPY is mounted - life is good.... nobody move.

#

@idle owl I think the changes since then only impact the arduino boot.

idle owl Oct 24, 2017, 9:49 PM

#

Ah I think you're right. I remember that now

tulip sleet Oct 24, 2017, 9:50 PM

#

@idle owl did you try the one in https://github.com/tannewt/uf2-samd? I don't know how far Scott got on it?

GitHub

tannewt/uf2-samd

uf2-samd - MSC bootloader (based on UF2) for SAMD21 and SAMD51

idle owl Oct 24, 2017, 9:50 PM

#

Did that need to be built?

solar whale Oct 24, 2017, 9:50 PM

#

I am using that now and it works well.

tulip sleet Oct 24, 2017, 9:51 PM

#

@solar whale are you using the UF2 functionality?

#

or just bossac

solar whale Oct 24, 2017, 9:51 PM

#

Yes

idle owl Oct 24, 2017, 9:51 PM

#

I want to get a bootloader.bin or .elf file to Kurt so he can get it on his M4

slender iron Oct 24, 2017, 9:51 PM

#

I'm working on the self updater for uf2 now

#

I think it finially flashed but hosed the bootloader...

solar whale Oct 24, 2017, 9:52 PM

#

I have been using it with no problems - on my MAC anyway

#

@slender iron are you referring to reloading the bootloader itself via UF2 - I loaded it with JLink, but I can load CP with it just fine.

slender iron Oct 24, 2017, 9:58 PM

#

I know

#

I think the bootloader is ok

#

but the self updater isn't

idle owl Oct 24, 2017, 9:58 PM

#

Ok, @formal plover is downloading the jlink software now. He's got a fresh M4 so he needs to start from scratch where we were this weekend. I have to go in a few minutes here. @solar whale I gave him my bootloader.bin and bootloader.elf but they're older than the one you're using, so if you could upload yours that would be helpful.

pastel panther Oct 24, 2017, 9:59 PM

#

You can put me in the same cart as Kurt however I won't have my jlink until probably next week

solar whale Oct 24, 2017, 10:00 PM

#

@slender iron any objection to my sharing the current build?

drowsy geyser Oct 24, 2017, 10:04 PM

#

@slender iron Coming in late from a meeting. I was able to flash my M4 using my compiled image and bossac, but the UF2 load doesn't work (as you know).

pastel panther Oct 24, 2017, 10:04 PM

#

Is there any documentation/open issues/bug tracker for the current status of the M4 build?

#

I know @tulip sleet and @slender iron are fixing USB issues, but @idle owl was referencing progress being made from the weekend so I wasn't sure if there was more to the story

formal plover Oct 24, 2017, 10:22 PM

#

Downloaded the special version of jlink for the pi

#

trying to move the 99 rules

solar whale Oct 24, 2017, 10:23 PM

#

Ooh! I have not tried it on a pi yet. Good luck!

pastel panther Oct 24, 2017, 10:26 PM

#

@formal plover If you're up for it, you should document your methods so others can share in the joy

formal plover Oct 24, 2017, 10:27 PM

#

For sure @pastel panther! This is on a Pi, but I'm sure I'm not the only one doing this

pastel panther Oct 24, 2017, 10:28 PM

#

@formal plover that's what I was hoping for. Now that I think of it, a Pi might be a decent alternative dev environment for people in windows land

formal plover Oct 24, 2017, 10:29 PM

#

It's a cheap way of having a Linux box for those "You need Linux" moments. It works great for what I've been doing

drowsy geyser Oct 24, 2017, 10:30 PM

#

@pastel panther ... I actually just ordered a new desktop on which to install Ubuntu for just this purpose. 😃

formal plover Oct 24, 2017, 10:30 PM

#

Running and testing CircuitPython boards and Arduino boards isn't extremely resource heavy

drowsy geyser Oct 24, 2017, 10:30 PM

#

Though I've had good luck compiling in the Bash shell (Ubuntu) on Windows 10.

pastel panther Oct 24, 2017, 10:33 PM

#

I've heard from a coworker that it's actually pretty decent

#

I still have flashbacks from when I had to develop for a linux environment on a windows machine...

formal plover Oct 24, 2017, 10:34 PM

#

I can do without the GUI, but you know I'm a millennial, so if I can use the GUI, prob going to use it

#

lololol

pastel panther Oct 24, 2017, 10:35 PM

#

I would always use a GUI if it worked as well as command line. Heck, my IDE is a GUI

#

To each their own

sick creek Oct 24, 2017, 10:39 PM

#

@drowsy geyser well there is other bash shells in windows 10 like suse

drowsy geyser Oct 24, 2017, 10:41 PM

#

True, but the Ubuntu shell is supported. 😃

sick creek Oct 24, 2017, 10:42 PM

#

in circuitpython right?

#

pastel panther Oct 24, 2017, 10:46 PM

#

What do you mean by in circuitpython? CP being supported in Ubuntu?

#

AFAIK CP is fairly platform agnostic

#

for development at least

drowsy geyser Oct 24, 2017, 10:48 PM

#

@sick creek I'm confused. The standard Ubuntu shell is working, so why should I change?

pastel panther Oct 24, 2017, 10:48 PM

#

building from source may be easier or harder on different plaforms but using a CP should be doable on anything with a usb port and a text editor

solar whale Oct 24, 2017, 10:48 PM

#

@tulip sleet interesting observation - I rebuilt 3.0 with you mod to usb.c - on the Link Box, twice now it seems to mount CIRCUITPY when I open screen to acces the REPL -coincendence?

drowsy geyser Oct 24, 2017, 10:48 PM

#

@pastel panther I can confirm your assertion.

sick creek Oct 24, 2017, 10:49 PM

#

@drowsy geyser well adding option as you can use ubuntu, openSuse like a app

solar whale Oct 24, 2017, 10:49 PM

#

@tulip sleet definite correlation....

#

drowsy geyser Oct 24, 2017, 10:52 PM

#

@formal plover What's your operating environment? Like, which OS, and which debugger are you going to use?

tulip sleet Oct 24, 2017, 10:54 PM

#

@solar whale hah - so that's why I only saw CIRCUITPY once! Thanks for that! It's another clue.

solar whale Oct 24, 2017, 10:55 PM

is there a way to update the jlink firmware?

Dumb question, but you have the USB Micro connected to, yes? And the red wire on the cable is aligned with the "1" printed on the JLink?

@slender iron I removed the unused second MSC device, as you may have seen above. It still is not responding to queries properly from the host - for instance, the host asks if write-protect is on, and it doesn't answer properly. Your calls to the MSC library appear OK, but I have to dig deeper into the library impl. I downloaded the latest ASF4 zips from Atmel START (hoping against hope), but there's no change since last time.

slender iron Oct 24, 2017, 11:14 PM

#

kk, thats kinda what I figured

formal plover Oct 24, 2017, 11:14 PM

So yeahhh device is wrong?

ktown, limor and I were talking about switching to a shared tinyusb for ports in 4.x

@solar whale ok

@slender iron is tinyusb the impl in UF2?

slender iron Oct 24, 2017, 11:16 PM

nah, its a different open source one done by thach

tulip sleet Oct 24, 2017, 11:16 PM

oh, yeah, now I remember thach's website name!

#

we still have to get something working on 3.x. Hopefully it can be debugged.

slender iron Oct 24, 2017, 11:19 PM

#

I'm sure we can figure it out

formal plover Oct 24, 2017, 11:22 PM

#

We use the jlink to flash the bootloader, correct?

#

I mean, I wouldn't see any other way of doing it.

umbral dagger Oct 24, 2017, 11:23 PM

@formal plover That's how I did it

solar whale Oct 24, 2017, 11:23 PM

#

@formal plover yes - BTW I just end-for ended my caple so it looks like @umbral dagger and it still works!

formal plover Oct 24, 2017, 11:24 PM

Hmmmm

#

So the red doesn't go to 1 then

solar whale Oct 24, 2017, 11:25 PM

#

yes it does - on both ends

umbral dagger Oct 24, 2017, 11:25 PM

#

📎 image.jpg

#

my arrangement

solar whale Oct 24, 2017, 11:25 PM

#

key will force it on Metro - the otehr end has to go with red at 1 - regardless of direction

#

looks good

formal plover Oct 24, 2017, 11:26 PM

#

We have different cables then

solar whale Oct 24, 2017, 11:26 PM

#

no

umbral dagger Oct 24, 2017, 11:28 PM

#

The other way

📎 image.jpg

formal plover Oct 24, 2017, 11:28 PM

#

Well when my red is on the same side as "1" the ribbon cable goes over the top

#

of the jlink

umbral dagger Oct 24, 2017, 11:28 PM

#

Which just seems backwards to me

formal plover Oct 24, 2017, 11:28 PM

#

Well that's how I have it

#

lol so which is it

solar whale Oct 24, 2017, 11:29 PM

#

depends on which end is in the metro

umbral dagger Oct 24, 2017, 11:29 PM

Stupid question: does the board need power?

formal plover Oct 24, 2017, 11:32 PM

#

@pastel panther Yes, powering it via usb (the metro)

umbral dagger Oct 24, 2017, 11:32 PM

#

@formal plover That might be a problem.

formal plover Oct 24, 2017, 11:33 PM

#

metro powered via usb, that's no good?

umbral dagger Oct 24, 2017, 11:33 PM

#

@formal plover I believe people were saying that on the weekend

formal plover Oct 24, 2017, 11:33 PM

#

They were mentioning that on Macs

umbral dagger Oct 24, 2017, 11:33 PM

#

@formal plover @pastel panther The jLink won'y power the baord adequately ... power led is not lit

formal plover Oct 24, 2017, 11:34 PM

#

mine was lit

#

I'm not trying to power the board via jlink

#

jlink and metro are both plugged in

solar whale Oct 24, 2017, 11:35 PM

#

@formal plover It is helpful to use a 9V supply to the barrel connector - do you have one?

umbral dagger Oct 24, 2017, 11:35 PM

#

I use the barrel connector to power with the klink

formal plover Oct 24, 2017, 11:35 PM

#

I MIGHT have one from my Arduino Uno

#

That's 9v correct?

umbral dagger Oct 24, 2017, 11:35 PM

#

Yes

solar whale Oct 24, 2017, 11:35 PM

#

better check

umbral dagger Oct 24, 2017, 11:36 PM

#

A range is fine... 7-12 maybe.. 9 is typical.

pastel panther Oct 24, 2017, 11:36 PM

#

Just as long as the polarity is correct

solar whale Oct 24, 2017, 11:36 PM

#

Metro_m0 says 7-9

umbral dagger Oct 24, 2017, 11:36 PM

#

Makes sense since it's just getting 3v3 from it, and not 5 like the Uno

#

I'm still getting used to the 3v3 thing... I grew up with 5v. Everythign could take 5v.

solar whale Oct 24, 2017, 11:37 PM

#

@kurt with respect to the cable - at leas on mine if you unplug and swap ends then it will lie the other way to keep red on pin 1 - yours mey be different buts it works both was for me.

tidal kiln Oct 24, 2017, 11:39 PM

#

notches on same side w.r.t. to cable or not? they are different for the two ends for the adafruit one:
https://www.adafruit.com/product/1675

10-pin 2x5 Socket-Socket 1.27mm IDC (SWD) Cable - 150mm long

These little cables are handy when programming or debugging a tiny board that uses 10-pin 1.27mm (0.05") pitch SWD programming connectors. We see these connectors often on ARM Cortex ...

formal plover Oct 24, 2017, 11:39 PM

#

I don't have the barrel power supply

pastel panther Oct 24, 2017, 11:40 PM

#

In the picture theyre actually the same though it looks reversed. If you look, both connectors are oriented to the cable the same way

tidal kiln Oct 24, 2017, 11:41 PM

#

notch w.r.t. cable is different
notch w.r.t. pin1 is same
yes. it is confusing.

solar whale Oct 24, 2017, 11:41 PM

#

the "tab" always point away from the USB connector on the Jlink - one way the cable is on the tab side - the other way it is reversed.

formal plover Oct 24, 2017, 11:42 PM

#

I switched the cables, same deal

tidal kiln Oct 24, 2017, 11:43 PM

#

red is 1, trust that unless the notch/tab forces you to something different, at which point you need to stop and investigate

solar whale Oct 24, 2017, 11:43 PM

#

@formal plover in the long run a 9V supply will be helpful. I often have to disconnect the USB and power it form the 9V to get Jlink to connect.

#

not sure that is your problem now.

formal plover Oct 24, 2017, 11:44 PM

#

So the tab always has to face away from usb @solar whale?

#

That's what you said right?

tidal kiln Oct 24, 2017, 11:44 PM

#

1 has to be 1

pastel panther Oct 24, 2017, 11:45 PM

#

If you have a friend that plays guitar, you can raid their pedal box for a 9v adaptor. Stabbings may occour.

formal plover Oct 24, 2017, 11:46 PM

#

okay, well there's only a 1 on the jlink

solar whale Oct 24, 2017, 11:46 PM

#

@formal plover is tehre a conflict between @tidal kiln instructions and tab location? should eb the same red wire at pin1

#

the Metro is keyed - cant do it wrong

#

but the red wire shou be by teh arrow - outer edge of the board.

formal plover Oct 24, 2017, 11:47 PM

#

lol I think everyone has suggested a different way so far

#

red is on the 1 jlink

#

tabs are lined up on the metro

#

tab to slot

solar whale Oct 24, 2017, 11:48 PM

#

and on the metro red is at outer edge - there is a small arrow

formal plover Oct 24, 2017, 11:48 PM

#

yes

solar whale Oct 24, 2017, 11:48 PM

#

good to go

tidal kiln Oct 24, 2017, 11:48 PM

#

that sounds correct then

formal plover Oct 24, 2017, 11:48 PM

#

which means the notch lines up with the slot

solar whale Oct 24, 2017, 11:49 PM

#

I don't undestand

formal plover Oct 24, 2017, 11:50 PM

#

The notch/key on the cable, there's a hole for that on the metro

solar whale Oct 24, 2017, 11:50 PM

#

yes - only one way to plug it in.

formal plover Oct 24, 2017, 11:50 PM

#

Yaassss

#

lol that's what I mean

solar whale Oct 24, 2017, 11:50 PM

red wire will alway be oon outer edge - no matter which end of the cple you use

hopefully

Not sure what's on it now

solar whale Oct 25, 2017, 12:07 AM

I think it started with a bootlater that will work with an updated bossac - you can go taht route or use the jlink to load an image to it. You can also use the jlink to load a new bootloader taht supports UF2

slender iron Oct 25, 2017, 12:08 AM

#

so the uf2 bootloader I sent you all definitely has bugs

solar whale Oct 25, 2017, 12:09 AM

@slender iron so do you recomment sticking with bossac or using it as is for now?

#

@solar whale I do

#

@solar whale At least I think so.. rebuilding to be sure

#

@solar whale Yes, confirmed

Everything looks good except no screen/repl

#

Interesting thing: screen connect and does nothing. Existing takes forever... but if I reset the m4, screeen exists immediatly

solar whale Oct 25, 2017, 12:57 AM

#

did you load the new bootloader tonight?

umbral dagger Oct 25, 2017, 12:58 AM

#

Well, and saving the code onto CIRCUITPY halts execution but does not restart it. But CIRCUITPy is still there and the file has been updated.

tidal kiln Oct 25, 2017, 12:58 AM

#

@umbral dagger it'll do that, the os removed the device screen was connected to when you reset

umbral dagger Oct 25, 2017, 12:58 AM

#

@solar whale I believe so.. Ozone, the new bootloader bin that @slender iron posted

I tried turning on neopixel and using the self updater to do so but it has a crc problem

#

which I think means the bootloader flashed it wrong

#

ah, nope I think its a crash in the neopixel code 😃

umbral dagger Oct 25, 2017, 1:12 AM

#

On Mac it's... um... different

#

I get stuff from screen.. but can't get a repl prompt

solar whale Oct 25, 2017, 1:13 AM

#

@silent radish I cant get it run on Mac with Dans mod in place.

#

wait...

umbral dagger Oct 25, 2017, 1:15 AM

#

hmmmm

#

If I stick a print in my binky code I DO see youtput to screen

solar whale Oct 25, 2017, 1:15 AM

#

CIRCUTPY does mount on MAC but REPL does not work'

#

@idle owl found she had to remove main.py or code.py to get to REPL

umbral dagger Oct 25, 2017, 1:16 AM

#

@solar whale Saw the same on Mac, seeing the same on Linux

solar whale Oct 25, 2017, 1:16 AM

#

My screen session connects, but no response.

umbral dagger Oct 25, 2017, 1:17 AM

#

Huh

solar whale Oct 25, 2017, 1:17 AM

#

trying without dans mod

slender iron Oct 25, 2017, 1:17 AM

#

@umbral dagger what version are you running?

umbral dagger Oct 25, 2017, 1:17 AM

#

Ya... if I remove main.py (with no code.py) I get a repl, no problem.

drowsy geyser Oct 25, 2017, 1:17 AM

#

BTW, 3.0current does not work on a Feather M0 Express. Local build, flashed with bossac, no D:\CPYTHON and no REPL working. Tried various permutations.

umbral dagger Oct 25, 2017, 1:18 AM

@slender iron latest master

solar whale Oct 25, 2017, 1:19 AM

#

without DAns mod - REPL works on the Mac

umbral dagger Oct 25, 2017, 1:20 AM

#

in repl. copy main.py onto CIRCUITPY. C-d, code starts... AND I can get back into the repl.

solar whale Oct 25, 2017, 1:20 AM

@formal plover if you want to try this bootlaoder, it does work

formal plover Oct 25, 2017, 1:30 AM

#

@solar whale well gdb server doesn't appear to work so u dunno how I would go about flashing it

solar whale Oct 25, 2017, 1:31 AM

#

I think you can use jlink commander -- loadbin command

idle owl Oct 25, 2017, 1:31 AM

#

Let's see if it worked. Since I have no idea how to read what the jlink is telling me and it's still full of halt errors - but it did the same thing last time and it still loaded the bootloader.

solar whale Oct 25, 2017, 1:32 AM

#

unplug you USB - and reenter bootlader - if it pulses fast, it is the new one!

idle owl Oct 25, 2017, 1:32 AM

#

Pulses fast for just a second?

#

Or continues to

solar whale Oct 25, 2017, 1:32 AM

#

continues as long as USB is out

formal plover Oct 25, 2017, 1:32 AM

#

@solar whale okay. What's that command?

slender iron Oct 25, 2017, 1:32 AM

#

I believe the latest one will also have a different version string

solar whale Oct 25, 2017, 1:33 AM

#

thats no fun 😉

idle owl Oct 25, 2017, 1:33 AM

#

How do I find the version string?

solar whale Oct 25, 2017, 1:34 AM

#

enter bootloader - in METROM4BOOT open INFO_UF2.TXT

that might be the last I sent

its a WIP

#

trying to get the neopixel going

solar whale Oct 25, 2017, 1:35 AM

#

it works

idle owl Oct 25, 2017, 1:35 AM

#

I grabbed the one you uploaded last.

solar whale Oct 25, 2017, 1:36 AM

#

@formal plover once you get JLink connected at JLink> prompt try loadbin bootloader.bin (assuming you have bootlaoder.bin in currend directory)

#

@umbral dagger I forgot - On linux now I don;t get CIRCUITPY mounted until I connect screen and enter REPL

formal plover Oct 25, 2017, 1:39 AM

#

@solar whale uh, no. What? Lol

solar whale Oct 25, 2017, 1:41 AM

#

let me try it first

idle owl Oct 25, 2017, 1:41 AM

#

I tried doing it through JLinkExe and it's still 1.23.0

solar whale Oct 25, 2017, 1:41 AM

#

I think taht is correct

#

so loadbin command worked for you @idle owl

idle owl Oct 25, 2017, 1:43 AM

#

Either that or it had already worked with Ozone and loadbin did nothing......

#

If I put the output in, can you decipher it?

formal plover Oct 25, 2017, 1:43 AM

#

Where do I have to have the bootloader stashed to load it?

solar whale Oct 25, 2017, 1:43 AM

#

try it

#

in your current directory - or jsut specfy the path to it.

@idle owl you need to force it into bootloader - I do it by disconnectiin USB then doubletap - then restart and connect JLINK

slender iron Oct 25, 2017, 1:57 AM

I realized it be pretty easy because we're only at 48 mhz in the bootloader just like the SAMD21

@idle owl - if you disconnetc USB and just have 9v connected can you enter bootloader?

@solar whale I don't have a 9v adapter. This is all via USB

#

I entered the bootloader connected to USB

solar whale Oct 25, 2017, 2:08 AM

#

oh - sorry - I thought you had one -hmmm - how have you gotten around the "unable to halt" in the past?

idle owl Oct 25, 2017, 2:08 AM

#

I keep connecting it to a USB power adapter when I'm doing the jlink stuff.

#

I didn't. It was never corrected.

#

This time I reset it a few times, tried to force it into the bootloader, and reconnected it.

solar whale Oct 25, 2017, 2:09 AM

OK - you are in bootloader now - try connecting JLINK

idle owl Oct 25, 2017, 2:10 AM

#

Ok

#

First of all it resets when I plug the cable back into the M4, but the bootloader came back up.

#

@solar whale Now what do you want me to do to test it? It didn't give me the halt error until I tried to flash the bootloader. Should I try to do that again?

#

Or is it not clear that the process was successful...

I can rename main.py back to main.py while I'm in the REPL and then it lets me flow back and forth between the live serial connection and the REPL no problem. screen connect with main.py in /, and it won't accept input. Interesting. Wouldn't even let me do it from already being in the REPL before, so this is an improvement.

@solar whale k

solar whale Oct 25, 2017, 2:27 AM

#

@idle owl don't - it won't work on Mac.

idle owl Oct 25, 2017, 2:27 AM

#

Oh. Noted.

solar whale Oct 25, 2017, 2:28 AM

#

REPL will not work

idle owl Oct 25, 2017, 2:28 AM

#

I didn't realise compiling it affected how it worked on the device... I thought it was what it was.

#

I thought it might be different but I thought I was wrong.

solar whale Oct 25, 2017, 2:28 AM

#

the modification to usb.c is the issue

umbral dagger Oct 25, 2017, 2:28 AM

#

@hollow tartan FYI Ubuntu 17 released this past spring.

solar whale Oct 25, 2017, 2:28 AM

#

it works on Linux but not on Mac.

idle owl Oct 25, 2017, 2:29 AM

#

Ah. So it's not a general thing, it's specifically this.

solar whale Oct 25, 2017, 2:29 AM

#

yes

idle owl Oct 25, 2017, 2:29 AM

#

Ok. So I wasn't off there. Good to know.

tulip sleet Oct 25, 2017, 2:29 AM

#

I didn't check that in anywhere, just something to try.

solar whale Oct 25, 2017, 2:29 AM

#

I hope Raspberry Pi responds the same.

#

@formal plover once you flash it, you will not see CIRCUITPY until you connect via screen and start REPL

#

At least taht is how it works for me....

umbral dagger Oct 25, 2017, 2:33 AM

#

So it's "working" pretty much. Sort of. I can get it into a state where I can update code on CIRCUITPY, and it reloads. I can get into the repl consistantly. It takes a littel finessing to get there, though.

solar whale Oct 25, 2017, 2:34 AM

#

@formal plover for first try - don't use a main.py or code.py - just got to REPL

idle owl Oct 25, 2017, 2:35 AM

#

I'm having issues. Trying to diagnose.

solar whale Oct 25, 2017, 2:35 AM

#

ruh roh..

umbral dagger Oct 25, 2017, 2:35 AM

#

I have to force removal of main.py. moving to trash doesn't "stick". I have to move it to trash, disconnect, reconnect, get into repl, put main.py back. Then I seem good.

formal plover Oct 25, 2017, 2:35 AM

#

Welp can't get it to enter bootloader anymore

solar whale Oct 25, 2017, 2:36 AM

#

do you still have JLink connected - if so remove it.

formal plover Oct 25, 2017, 2:36 AM

#

No @solar whale

umbral dagger Oct 25, 2017, 2:37 AM

#

Removing from command line just works, though. Once I have main.py removed, CIRCUITPY does NOT show up until I screen in (getting dropped into the repl).

formal plover Oct 25, 2017, 2:37 AM

#

after I loaded the 3.0 @idle owl gave me it won't work

solar whale Oct 25, 2017, 2:38 AM

#

@formal plover ah - you may have to reboot your RPi --

idle owl Oct 25, 2017, 2:38 AM

#

Jlink again?... 😕

solar whale Oct 25, 2017, 2:38 AM

#

the USB issues can make it very unhappy.

formal plover Oct 25, 2017, 2:39 AM

#

@idle owl is fired

idle owl Oct 25, 2017, 2:39 AM

#

shows herself out

solar whale Oct 25, 2017, 2:39 AM

#

or try this: sudo systemctl restart systemd-udevd

formal plover Oct 25, 2017, 2:39 AM

#

lol just rebooting

solar whale Oct 25, 2017, 2:40 AM

#

okay - tuck that away for next time.

formal plover Oct 25, 2017, 2:40 AM

#

I need to spin up another pi

#

This is my pihole server

#

constant reboots are no fun

#

lol

umbral dagger Oct 25, 2017, 2:40 AM

#

I love Pis.. they're so cute.

#

I need more of them.

idle owl Oct 25, 2017, 2:40 AM

#

@formal plover Hey I know the guy who wrote PiHole! He just did a preso at the group I had a board meeting for tonight. He'll be presenting again in December.

formal plover Oct 25, 2017, 2:41 AM

#

@idle owl say whattttt???

#

That's awesome

solar whale Oct 25, 2017, 2:42 AM

#

@formal plover does the board enter bootlaoder - taht is neopixel on even if you dont see METROM4BOOT?

idle owl Oct 25, 2017, 2:42 AM

#

Ok, @umbral dagger thank you for mentioning the force removal of main.py. Mine is now acting like the rest do, where when I connect it, it doesn't show up until I connect to the REPL.

formal plover Oct 25, 2017, 2:43 AM

#

Oh man it's really borked now

solar whale Oct 25, 2017, 2:43 AM

#

@idle owl Wow - I had not gotten to that stae on the Mac, but there is something still funky with USB

#

@formal plover is taht a technical term?

[adafruit/circuitpython] Issue opened: #368 atmel\-samd: lto\-type\-mismatch and ERROR 1 on build

Output below. I am using Ubuntu 16.04. I have compiled the UF2-SAMD21 without errors and flashed the bootloader.bin so my toolchain worked for that. (The bootdrive shows up on a double click but nothing else) I just cloned circuitpython today and tried a few boards but all the same. Typical output below. I do not understand the error at all.

Output:
/circuitpython/atmel-samd$ make V=1
GEN build-metro_m0_express/genhdr/qstr.i.last

#

@solar whale "borked" oh ya. I've heard that used for... like... ever

formal plover Oct 25, 2017, 2:45 AM

#

@solar whale lol sure is

umbral dagger Oct 25, 2017, 2:46 AM

#

@idle owl main.py running, can screen in but not get into the repl. Remove main.py on commnad line (none of that GUI second change nonsense... GONE.) and it drops me into the repl.

idle owl Oct 25, 2017, 2:46 AM

#

It took some nonsense to even let me do it via commandline.

solar whale Oct 25, 2017, 2:46 AM

#

@formal plover waht is happening?

umbral dagger Oct 25, 2017, 2:47 AM

#

@idle owl Then if I copy it back onto CIRCUITPY and C-d it starts up and I can get back to the repl as expected. C-c <return>

#

Maybe some weird threading issue keeping the repl from starting? If so it could be that main.py loads and starts execution so much faster on the m4. I'll have a peek at the startup code.
