Problem with flashing firmware

This looks not correct. There should be an unique serial instead of all 0.

Likely, your board is not correctly flashed or you made mistakes during make menuconfig.
See Issues flashing the printer board and strictly adhere to the information on top of klipper/config/printer-sunlu-t3-2022.cfg at master · Klipper3d/klipper · GitHub
Also inspect your MCU chip to get this correct.
