Describe your issue:

hi, I have been trying to upgrade my 3d printer Sovol “SV08” to full Klipper. everything goes great until flashing the MCU it freezes at “Attempting to connect to bootloader” I’m not sure what to do. I have verified my MCU id by disconnecting the toolhead and running “ls -la /dev/serial/by-id/”

biqu@sv08:~$ ls -la /dev/serial/by-id/
