FAST System Firmware Compilation Tutorial

warning

• FlyOS-FAST System Notes
  • The default username for the FAST system is root, and the password is mellow
  • Firmware compilation can only be performed using the root user
  • And the FAST system only has the ROOT user, no need for you to switch users!!!

::: tip

• Please ensure that the host machine can connect to the network normally.
• Before compiling the firmware, use SSH to log in to the host machine via the network.
• Do not use a serial port tool to log in to the host machine.

Below is an introduction on how to compile the firmware:

• After connecting via SSH, enter the following command and press Enter:

  cd ~/klipper && rm -rf ~/klipper/.config && rm -rf ~/klipper/out && make menuconfig

• The command rm -rf ~/klipper/.config && rm -rf ~/klipper/out is used to delete previous compilation data and firmware.

• make menuconfig is for compiling the firmware. After execution, the following interface should appear:

  

• Select Enable extra low-level configuration options and press Enter.

  

• Navigate to the menu Micro-controller Architecture and select STMicroelectronics STM32, then press Enter.

  

Images are being updated

• Enter the menu Processor model, select STM32F405, and press Enter.

  

• Select Bootloader offset, choose: 32KiB bootloader.

  

• Select Communication interface, choose: USB to CAN bus bridge (USB on PA11/PA12).

• Follow the image to select CAN bus interface (CAN bus (on PB8/PB9)) --->.

  

• Press the Q key, and when Save configuration appears, then press the Y key
  
• You should now have saved the configuration and returned to the command line interface
• Enter the command below to start compilation; it will take a while

make -j4

• If the following content is output at the end, the compilation is successful
• Due to Klipper version differences, as long as out/klipper.bin appears, it indicates success

  Linking out/klipper.elf
  Creating bin file out/klipper.bin
