Manta M8P+CB1+U2C+EBB36

[limber garnet]

hey everyone i am getting my new electronics setup with the above. i have already setup klipper and mainsail on the Manta M8P and already tested things work before trying to setup can. i believe i have a v1 manta board. i am following this guide (https://www.youtube.com/watch?v=5pLjeQz9pEI) with this referene(https://github.com/meteyou/KlipperMisc/tree/master/BigTreeTech-U2C) (https://github.com/meteyou/KlipperMisc/tree/master/BigTreeTech-EBB36-v1.1). but when i come to this section to run this command(python3 ~/CanBoot/scripts/flash_can.py -f ~/klipper/out/klipper.bin -d <serial device>) i get an error. everything else has gone just fine up until this point.
here is my error
in my opinion i am a noob when it comes to this. i really dont understand what im doing with most commands so let me know what you may need me to check. i have the newer version U2C and EBB 36

[north monolith]

I thought newer mantas have native can support and don’t need the u2c

[limber garnet]

no clue.

[north monolith]

What version M8p do you have? Gargamel is the CAN expert from what I’ve read/heard, I’m sure he’ll be along to clarify

[limber garnet]

i have been reading a thread where he helped someone else with an m8p but im very confused by most of what i am reading.

[wide meteor]

@limber garnet run the command pip3 install pyserial

[limber garnet]

boom. okay now let me see where i get stuck next

[limber garnet]

THX😭

[wide meteor]

I just read the error message you sent haha

[limber garnet]

🤦‍♂️

[limber garnet]

i now get no uuids to show up.

[wide meteor]

After you put the UUID in your printer.cfg I assume?

[limber garnet]

im at the point of flashing the ebb 36 with klipper. yes i added the U2C to the cfg and also the temp shows up.

[wide meteor]

Yes, that’s expected

The uuid won’t show up if it’s being used

[limber garnet]

i have my ebb36 plugged into the u2c with the high and low pins and powered off a usb. i have flashed the boot loader already on the ebb36. shouldnt i get one for the ebb36?

[wide meteor]

U2C has a thermistor on it?

Oh wait

what’s the temp from, not your ebb36?

[limber garnet]

per the guides im following above there is. now my printer wont startup. mainly following the teching tech guide

[wide meteor]

Did you flash can boot to your u2c ??

[limber garnet]

yes

[wide meteor]

I haven’t never done it this way. Usually you want candlelight on your u2c to have it acting as a can bridge only, not actually part of your network

[limber garnet]

should i redo the flash of candlelight on the u2c and than just forgo the boot loader on the u2c and move to the install of the ebb36?

[wide meteor]

I would personally

Candlelight on u2c, flash can boot to ebb36, then plug them in and when you search for uuids the one that comes up will be your ebb36

[limber garnet]

will report back.

i get this error when i try to search for can ids with the u2c flashed with candlelight only and the ebb36 not plugged in. i should get something saying no uuids found correct?

[wide meteor]

im not an expert on this part but no, u2c isn't part of the can network in this setup, just acting as a can bridge between sbc and ebb -- so without the ebb plugged in there is not a can network yet

[limber garnet]

is there a way to check the candlelight firmware is flashed corectly other than using the above command? i plugged the ebb 36 in and get the same error.

[wide meteor]

ip -s link show can0

[limber garnet]

says device "can0" doesnt exist

[wide meteor]

sudo nano /etc/network/interfaces.d/can0 ?

[wide meteor]

allow-hotplug can0
iface can0 can static
bitrate 500000
up ifconfig $IFACE txqueuelen 256
pre-up ip link set can0 type can bitrate 500000
pre-up ip link set can0 txqueuelen 256

[north monolith]

Same…

Gonna have to watch like 10 videos on it before I try it with my setup…

[wide meteor]

ok

lsusb

wait you rebooted right?

[limber garnet]

rebooted.

[wide meteor]

you used the btt fw right?

[limber garnet]

for U2C? yes. is there a way to check?

[wide meteor]

assuming you got it from this link then its the right one

https://github.com/bigtreetech/U2C/blob/master/firmware/U2C_V2_STM32G0B1.bin

ive used this before with success though too

https://canable.io/updater/canable1.html

[limber garnet]

i did not use that github address for my install i believe i used this on (https://github.com/bigtreetech/candleLight_fw)

[wide meteor]

hm flash that newer one, i dont think that one is updated for the v2

[limber garnet]

run this command but with the first address you provided?

[wide meteor]

probably, whats the rest of that command

are u using dfu util

[limber garnet]

what do you mean?

[wide meteor]

what command are you typing to get the fw onto the u2c ?

[limber garnet]

wouldnt that be the U2C in dfu mode and use this command "make flash-candleLight_fw"

[wide meteor]

gotta clone the exact file

U2C_V2_STM32G0B1.bin

[limber garnet]

i dont really know what format you mean.

[wide meteor]

git clone https://github.com/bigtreetech/U2C/blob/master/firmware/U2C_V2_STM32G0B1.bin

[limber garnet]

same error.

[wide meteor]

ok it's easier to use stm32 cube programmer then

just download that bin and program it on pc

[limber garnet]

is there a guide for that?

[wide meteor]

just plug it in and select the bin file

[limber garnet]

in here?

[wide meteor]

yep

[limber garnet]

do i need to check any boxes or anything?

just hit start programming?

[wide meteor]

yeah just send it

[limber garnet]

okay so i got it plugged back into the main board. now what?

[wide meteor]

now run those commands on your pi again to see if it works

[limber garnet]

with Ebb 36 plugged in with usb power and can cords hooked up.

[wide meteor]

did you reboot ?

[limber garnet]

yes, im going to redo the EBB36 bootloader just in case.

[wide meteor]

wait type

cat /etc/*-release

[wide meteor]

ah

sudo nano /etc/systemd/network/80-can.network

[Match]
Name=can0

[Network]
BitRate=1000000

[limber garnet]

i have everything else i believe at 500000

[wide meteor]

actually before you do that you can just force the network online

sudo ip link set up can0

[wide meteor]

weird distro

sudo systemctl status systemd-networkd

[wide meteor]

ifconfig can0 Up

or ifup can0

[wide meteor]

sudo it

sudo ifup can0

[wide meteor]

ah i keep forgetting what net manager this is using

sudo ip link set dev can0 up

[limber garnet]

also i may have the incorrect jumpers. i dont have the 120r jumper on anything.

[limber garnet]

i have contacted btt to see what they say. hopefully they should know because its all there products.

[wide meteor]

I hate not being able to get something working 😡

I just bought one of these to try and get it working

gets here tomorrow

[limber garnet]

been a big help so far and its greatly apprecidated.

[north monolith]

I’ll need help soon! Lol, mine arrives today.

[wide meteor]

and you do have a v1.0 and not a v1.1 right ?

[limber garnet]

per the amazon seller. is there a way to tell? #1066412196923449466 message

[wide meteor]

Send a picture of it

[limber garnet]

be home in next hour so will do.

[wide meteor]

damn, v1.1 supports CANBUS natively so you wouldn’t even need a u2c 😭

[limber garnet]

I looked for one but couldn't find anything when I ordered but guess I'm just bad at looking

[wide meteor]

btw is that an 05 scooby in your profile pic ?

[limber garnet]

05 sti yes. Wrx trunk on it at the time.

[wide meteor]

hell yeah, I’m a bit of a subie fanatic

My main is a 06 sti but I have an 05 FXT and an 05 WRX hatch too

[limber garnet]

Stable is a 05 sti but being built into a track car by myself currently. Daily a 03 Forester. And my gf has a 96 Impreza.

[wide meteor]

Yeah my forester is my daily too

How crazy you going w the sti build?

[somber fern]

I had an issue where the bootloader does not like going on to the ebb36 v1.2 you have to compile it, download it and install with STM software.

I also have a m8p, no complaints amazing bit of kit.

[limber garnet]

im guessing i can use STM32 to install my boot loader. and than continue?

[somber fern]

Yeah but you can't update via canboot.

[limber garnet]

so whats the point?

[somber fern]

It's only the ebb32 v1.2 that's not working. Should be a bootloader fix coming out soon though.

[limber garnet]

so i guess i do my make menu config for the klipper flash for the ebb36 and than use stm32 to flash the ebb36 with klipper? should i remove the bootloader?

[somber fern]

Exactly what I done, yeah remove bootloader.

But you have to do it everytime you update klipper. 😭

Mine is running 250000 if that makes a difference.

[limber garnet]

its a pain but i guess ill have to deal for now until fixes come out. i am unsure how to remove the boot loader, if anyone has tips. i will try 250000 just for shits and giggles. ill try re doing my setup tonight with no bootloader.

[somber fern]

You might have to flash the bootloader from the btt repo first.

In STM there is an erase chip option to get rid of the boot loader.

[limber garnet]

onto the EBB?

[somber fern]

Yeah.

https://github.com/bigtreetech/EBB/blob/master/EBB CAN V1.1 (STM32G0B1)/firmware_USB.bin

[wide meteor]

your CAN network still has to be up to connect though

[somber fern]

https://github.com/bigtreetech/EBB/blob/master/EBB CAN V1.1 (STM32G0B1)/firmware_canbus.bin

[limber garnet]

also found this video from btt but i dont know if it will work. https://www.youtube.com/watch?v=GaMOe1yirPk

[wide meteor]

What do they flash the u2c with in that video

[limber garnet]

ill do more research tonight,

[wide meteor]

My u2c gets here tonight and I should have some time to play around with it

[somber fern]

I just flashed the bootloader from the btt website, then with klipper.

[limber garnet]

you did the usb first than the cabus install?

[somber fern]

No I posted the wrong link. Just do the canbus.

[limber garnet]

i dont think they do.

[limber garnet]

do you flash the EBB and than do the make menuconfig?

[limber garnet]

i have tried recompiling and flashing and still get this error when searching for uuids.

[somber fern]

Have you got the resistor in place?

[limber garnet]

on the EBB yes

[somber fern]

I'm not sure then. Can you run a usb scan to see what's connected just to make sure the u2c is connected and working?

lsusb -v 2>&1 1>/dev/null

Think that will tell you what usb things you have connected.

[limber garnet]

will try tonight

[wide meteor]

why not just lsusb

[somber fern]

If that shows everything so that. I'm no expert just piecing together bits from how I got it working. With a lot of help from gargamel.

[wide meteor]

yes, garg is the goat haha

[limber garnet]

so got another U2C and i have done nothing besides plug it in place of the other one. and get this. with no EBB36 plugged in.

[wide meteor]

nice

[limber garnet]

i dont get the ebb to register yet but one step closer.

[somber fern]

That's correct. As the u2c does not show. It will only give you an I'd when the ebb36 is connected.

[limber garnet]

so im trying to flash klipper to the EBB and im not seeing any uuids. i have tried 120 jumper on ebb and both also.

[wide meteor]

ebb36 has canboot?

[limber garnet]

havent messed with it much but btt said i need to do the flash with 24v not jumper power. havent tried it yet but maybe.

[limber garnet]

still get same issue get no uuids to show up. with using full can wriring and having both 120R caps on.
