Support for new Creality boards 4.2.2 with GD32F303

Hi friend,I bought a GD32F303 Ender3v2 3 days ago. I try 10+ config and cannot flash the firmware sucessfully.

Through this msg “GD32F303 is not a clone of STM32F303. It is stil a compatible chip of sTM32F103”


But I also try and failed.

One thing i can confirm is no trouble on my host software, because when i flash back the official firmware “/dev/serial/…” is ok while flash klipper firmware is “no such file/dir /dev/serial/…”.

I cannot find the way to trouble shooting, because I cannot find firmware error log, just “mcu: Unable to open serial port: [Errno 2] could not open port /dev/serial/” in klipper log.
