I have finally got klippered snapmaker original 3D printer.
I introduce “how.”
Btw I could not figure out how to implement self update firmware and its bootloader. So my method needs JTAG cable to re-flash the control board. I mention that the control board uses GD32F105RC and it is compatible to STM32F1XX mcu.
((Klipper Firmware Configuration))
Enable extra low-level configuration options: ON
Micro-controller Architecture: STMicroelectronics STM32
Processor model: STM32F103
Only 100KiB of RAM: OFF
Disable SWD at start up: OFF
Bootloader offset: No bootloader
Clock Reference: 16MHz crystal
Communication interface: Serial on USART1 PA10/PA9
Baud rate for serial port: 460800 (stable value for CH340 chip)
GPIO pins to set at micro-controller startup: Just default
((Re-flash)) I use J-Flash (Segger J-link cable) . this is my .jflash file
