Unable to update firmware after updating klipper - mainsail

[midicdj1000]

I just flashed the Leviathan with klipper 11 and then told mainsail to update everything. Now I can't flash new firmware it says it can't find the usb port.

I press sw1 twice and the boot loader led flashed.

Run the command to check it is showing

pi@mainsailos:~ $ ls /dev/serial/by-id/*

/dev/serial/by-id/usb-katapult_stm32f446xx_1B0047000451313133353932-if00

I run the flash command ~/klippy-env/bin/python ~/katapult/scripts/flashtool.py -d /dev/ttyACM0 -f out/klipper.bin

and it gives this error

pi@mainsailos:~/klipper $ ~/klippy-env/bin/python ~/katapult/scripts/flashtool.py -d /dev/ttyACM0 -f out/klipper.bin ERROR:root:Flash Error Traceback (most recent call last): File "/home/pi/klippy-env/lib/python3.9/site-packages/serial/serialposix.py", line 265, in open self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK) FileNotFoundError: [Errno 2] No such file or directory: '/dev/ttyACM0'

With some help from the klipper discord this command worked

~/klippy-env/bin/python ~/katapult/scripts/flashtool.py -d /dev/serial/by-id/usb-katapult_stm32f446xx_1B0047000451313133353932-if00 -f out/klipper.bin

it needed the full dev device instead of the ttyACM0

[camerony]

Can I get some more information? What versions of the RPi are you using? Also the OS version, Bookworm or Bullseye? What is in your /boot/cmdline.txt ?

Also does /dev/ttyACM0 exist?

[midicdj1000]

PI 3B+

How do I check for /dev/ttyACM0 ?

[camerony]

ls /dev/tty*

[midicdj1000]

[midicdj1000]

how do you know what it's allocated to ? something must have changed between the first flashing and all the upgrades.

[midicdj1000]

I forgot to show cmdline

[camerony]

That is your USB port, not sure what happened. But it should work with /dev/ttyACM0, if the Leviathan is the only device plugged in to the Rpi.

[midicdj1000]

It did work the first time before all the updates

[camerony]

Does it work now though? I'll haven't been able to reproduce your issue, since /dev/ttyACM0 exists.

[midicdj1000]

when I put it into bootloader mode it changes the list of ports

ttyAMC1

[midicdj1000]

and it does not program

[midicdj1000]

if I change to ttyACM1 it programs ok

[camerony]

Ok, thanks. Not sure why you're not getting /dev/ttyACM0 in bootloader mode. But at least we confirmed it does work, just that it got reassigned as /dev/ttyACM1. I'll see if can reproduce that.

[midicdj1000]

it would be a lot easier to use the /dev/serial/by-id/usb-katapult_stm32f446xx_1B0047000451313133353932-if00 with the unique id, you ask to check this is present so why not use it and save any potential problems with the ACM0

[camerony]

true, I'll add that is a second option. Thanks for troubleshooting.

[midicdj1000]

Can you explain the USB, CAN and UART options at the start. If I am using UART to talk to the PI will this stop me using CAN to connect to a toolhead board ?

I setup with USB to talk to the PI and want to use CAN connect to a BTT board once I have everthing else setup.

I suggest you join https://discord.com/channels/692982154577313814/1180911286142369842 for that question.

added addition command option
