USB Firmware Compilation

tip
  • The Super8 comes with a pre-flashed TF card bootloader, so you don't need to flash it again.

Getting Started with Compilation​

  • You need an upper computer with the klipper service installed Connect via SSH over the network
  • And make sure the device is connected to the upper computer
  • Note: Please use a regular upper computer, such as a Raspberry Pi FLY board, etc. If you are using a modified upper computer, we cannot provide much assistance due to too many issues.
Note
  • Do not use the ROOT user
tip
  • 请确保上位机可以正常联网
  • 固件编译前需要使用SSH通过网络登录上位机
  • 请不要使用串口工具登录上位机

如果配置页面选项比较少，请先勾选[ ] Enable extra low-level configuration options，用于显示部分隐藏选项

Below is an introduction on how to compile the firmware:

  • After connecting to SSH, enter the command below and press Enter:

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

  • Among them, rm -rf ~/klipper/.config && rm -rf ~/klipper/out is to delete previous compilation data and firmware, and make menuconfig is to compile the firmware. After execution, the following interface should appear:

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

  • Enter the menu Micro-controller Architecture and then select STMicroelectronics STM32 and press Enter

  • Enter the menu Processor model, select STM32F407 and press Enter

  • Select Bootloader offset, choose: 32KiB bootloader

  • For Communication interface, choose: USB (on PA11/PA12)

  • Press the Q key, and when Save configuration appears, press the Y key.

  • You should now have saved the configuration and exited to the command line interface.

  • Enter make -j4 to start compiling; this process may take some time.

  • If the final output is as follows, the compilation was successful:

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

Flashing the Firmware​

Preparation​

  • Before flashing the firmware, please first connect via SSH using the network
  • Counterfeit memory cards may cause flashing failure, please try to use the recommended memory cards below for firmware update
  • Prepare a TF card with a capacity not exceeding 32G, and it is recommended that the transfer speed of the TF card must be class10 or higher, it is suggested to use brands like SanDisk for the TF card

Download Firmware​

  1. Use the prepared TF card
  2. Format using SDFormatter
  3. Use MobaXterm_Personal to navigate to the file directory on the left side, find klipper, then open out
  4. Download klipper.bin to the TF card and rename it to firmware.bin
  5. Power off the motherboard, insert the TF card into the motherboard
  6. On the motherboard, wait for 10 seconds
  7. Remove the TF card and insert it back into the computer. If the firmware.bin in the SD card disappears and FLY.CUR appears, the flashing is successful.
