Problem setting up CAN-Bus - no UUID after flashing klipper

Printer Model: Voron 2.4
MCU / Printerboard: Octopus, U2C, SB2209

Hi,

after several days this seems to be my last hope.

The setup works perfeclty until flashing the SB2209. Katapult can be flashed onto the SB2209 and there is an UUID. Flashing Klipper also seems to work but after that, there is no longer any UUID available, and this is where I’m stuck. Expected was the UUID and Application: Klipper.

Anyone any ideas?

The problem was solved by flashing klipper via USB in DFU-Mode. Any errors during the flashing don’t seem to be a problem.
