is there a developer that can look in my logs 🥰

warm stag Jan 30, 2023, 11:18 AM

#

Nope as we are mainsail, and not Klipper or rPI Foundation.And by the way your tags are writing that is purely a Klipper setup issue.

#

It is also very hard to check as you did not link the source of your guide you used

Klipper

ADXL345 Raspberry pi4 multi SPI

thanks, it’s a bit more clear now. did you activate manually the spi3-6 of the raspberry in the config?

#

since mainsail gives a error i tagged it mainsail, the klipper tag was wrong sorry about that

warm stag Jan 30, 2023, 2:10 PM

#

Mainsail is always the deliverer of all messages. So please shoot the sender not the deliverer 😉

eager bough Jan 30, 2023, 2:10 PM

but there is no klipper discord?

eager bough since mainsail gives a error i tagged it mainsail, the klipper tag was wrong sor...

no... thats more wrong than before... the klipper tag was the only right tag, because you have a klipper error. mainsail is just a gui and will display all error messages from every component, but only because it display the error for you, its not the issue...

totaly lost with linux realy

#

no probs

#

#

meteyou the above pictures i dont get i ask in config to open spi5-1cs and spi6-1cs but the only ports that are open are spidev0.0 and spidev0.1 iam sorry to ask you guys this but otherwise i will never get this fixed

#

dont get the parameter dtparam=spi=on must it be on the work or does it need to be dtparam=spi=off

lost steppe Jan 30, 2023, 3:44 PM

#

i can check it, when i'm at home. i have done the same think for 2-3 weeks and i think a have some docs about this...

open Mainsail -> System Tab -> there you see your linux mcu and the klipper version when you build it

eager bough Jan 30, 2023, 4:24 PM

#

#

now the question is am i using old mcu code before 21/9/22 or after

#

if before i need to use symlinks if after i dont need symlinks

warm stag Jan 30, 2023, 4:31 PM

#

I do not see your Linux mcu at all

#

#

Do not sounder mine is dirty as I have test code in my repo

eager bough Jan 30, 2023, 4:32 PM

v0.10.0-620-g11dd273b

warm stag Jan 30, 2023, 4:42 PM

#

ok as this is a task of minutes do the following

#

ssh in the PI

#

make clean
make menuconfig```

#

select linux as microcontroler all other options default. Quite and save

#

make flash

#

and then we are sure you have the latest version

eager bough Jan 30, 2023, 4:48 PM

#

#

thx alexz i think it update to the newest now Version: v0.11.0-87-g0407c24c

warm stag Jan 30, 2023, 4:54 PM

#

you can see that number but now it should be latest

eager bough Jan 30, 2023, 4:54 PM

#

in mainsailos it is still stated as version v0.10.0-620-g11dd273b

#

i rebooted the rpi after the make flash command..

warm stag Jan 30, 2023, 4:58 PM

Make an force refresh of your browser

eager bough Jan 30, 2023, 5:03 PM

i did that also back restarted the pi but under host there is no version stated as before

You are in shutdown but yes know you are on latest

ok then now i know that i dont need symlinks

#

still spi0 c1 and spi0 c0 showing in gpioinfo

this is whats in boot/config.txt

😘 no problem realy thank you for trying to help even when its a klipper thing, looking forward to your replaiy when you looked at it

The description is for a pi4

eager bough Jan 30, 2023, 5:49 PM

the pi3b v2 has the same gpio

warm stag Jan 30, 2023, 5:49 PM

You have spi=on in there 2 times

eager bough Jan 30, 2023, 5:49 PM

ok i will remove one

warm stag Jan 30, 2023, 5:51 PM

No pi3 here to text it myself

i removed spi=on still same output

Ähnlich

dtoverlay=spi5-1cs
dtoverlay=spi6-1cs```

Compare it to your until you find the difference 😉

#

Spoiler look at the first line of the 3

dtparam=spi=off results in above

warm stag Jan 30, 2023, 6:24 PM

ls /dev/*spi*

#

But on results in (pi4)

eager bough Jan 30, 2023, 6:29 PM

is i2c arm on also needed for only spi

warm stag Jan 30, 2023, 6:29 PM

#

No normally not

eager bough Jan 30, 2023, 6:54 PM

#

ok then the symlink way

#

can you tell me how i can do that ?

warm stag Jan 30, 2023, 6:58 PM

Nope but why do you not simple use spi0 and1

#

#

this is how it is wired now

warm stag Jan 30, 2023, 7:05 PM

Yes he is taking about an pi4 and I showed you that it is working on a pi4

I have no pi3 laying around here so I can not crosscheck

#

do a pinout on your rpi4

#

what can be a problem is the bluetooth on my 3b v1.2

#

On the Raspberry Pi Model 3B the hardware-based serial/UART device /dev/ttyAMA0 has been re-purposed to communicate with the the built-in Bluetooth modem and is no longer mapped to the serial RX/TX pins on the GPIO header. Instead, a new serial port "/dev/ttyS0" has been provided which is implemented with a software-based UART (miniUART). This software-based UART ("/dev/ttyS0") does not support PARITY and some have experienced some stability issues using this port at higher speeds. If you don't need Bluetooth functionality, you can disable the BT modem and configure the RPi to use a device-tree overlay to re-map the hardware-based serial UART ("/dev/ttyAMA0") back to the GPIO header pins for TX/RX. See the instructions on this page for details on how to configure the device-tree overlay and disable the bluetooth modem/service:

warm stag Jan 30, 2023, 7:10 PM

#

UART != SPI

#

Yes both share a 40 pin connector but that does not mean you have the same capabilities on the bus side

@lost steppe do you maybe have a idea before i give up?

eager bough Jan 30, 2023, 8:56 PM

Raspberry Pi Zero, 1, 2 and 3 have three SPI controllers:

SPI0, with two hardware chip selects, is available on the header of all Raspberry Pis; there is also an alternate mapping that is only available on Compute Modules.

SPI1, with three hardware chip selects, is available on all Raspberry Pi models except the original Raspberry Pi 1 Model A and Model B.

SPI2, also with three hardware chip selects, is only available on Compute Module 1, 3 and 3+.

On the Raspberry Pi 4, 400 and Compute Module 4 there are four additional SPI buses: SPI3 to SPI6, each with 2 hardware chip selects. These extra SPI buses are available via alternate function assignments on certain GPIO pins - see the BCM2711 ARM Peripherals datasheet.

Chapter 10 in the BCM2835 ARM Peripherals datasheet describes the main controller. Chapter 2.3 describes the auxiliary controller.

#

raspi3 only has spi0 spi1 spi2

#

rasp4 has spi3 to spi6

my mcu is on v0.10 and mcu rpi is on v0.11 is this normal alexz

warm stag Jan 30, 2023, 9:29 PM

Yes we only updated the Linux mcu and not you physical printer board

#

They can have different versions

#

So that means you can not activate 5 and 6

There is were no SPI2 to SPI6 interfaces before the Raspberry 4 (and Compute Module). So one should not be surprised if the installation of any of these fail on a Raspberry Pi 3 B or earlier model.
