Configs

  • Is the SKR status LED flashing slowly indicating that the board is in the katapult bootloader mode?
  • Have you tried issuing a lsusb command on the Pi to check if the board is detected?
  • Do you have a /dev/ttyACM1 (or perhaps /dev/ttyACM0) device? If yes, you may be affected by Debian 11 (Bullseye) udev bug - No board or serial found
