Hi @mykepredko, when I tried copying that line after setting my klipper menu config, I don’t think I have managed to successfully flash the MCU with the Klipper.bin firmware. I was running into the same issue getting any file or directory found when entering ls /dev/serial/by-id/*. I even tried the fixes mentioned by @Sineos at the beginning of his install guide in Installing Klipper with KIAUH and still it absolutely would not work.
This is the error I get when I implement your method:
T he BTT M5P manual did warn about the invalid DFU suffix signature and error get_status, although, I could not see any indication that the firmware has flashed successfully, unless it has and I’m just being paranoid?
