USB Firmware Compilation

Start Compilation

• A host machine with the installed klipper service is required Connect via SSH over the network
• Make sure the device is connected to the host machine
• Note: Please use a regular host machine, such as a Raspberry Pi FLY board, etc. If it's a modified host machine (e.g., WiFi stick, Redmi, etc.), due to too many issues, we cannot provide technical support for these machines

warning

• To switch from the ROOT user to a regular user, you can enter the command below
• Do not use the ROOT user
• For the fly user, you can directly enter: su fly. For non-fly users, please replace <your host machine username> with your host machine's username!

su <your host machine username>

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

2. 确认键Enter 或 空格键Space，用于勾选菜单或进入子菜单
3. 退出键ESC，用于返回上一级菜单
4. Q键，用于退出Klipper固件配置页面
5. Y键，在退出Klipper固件配置页面时，如果有提示，则点击Y键保存配置文件

warning

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 the introduction on how to compile the firmware:

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

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

• Where rm -rf ~/klipper/.config && rm -rf ~/klipper/out is to delete previous compilation data and firmware. 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 then select STMicroelectronics STM32 and press Enter

  

• Enter the menu Processor model, select STM32F072 and press Enter

  

• Select Bootloader offset, choose: 8KiB bootloader

  

• Communication interface, select: USB (on PA11/PA12) and press Enter

  

• Please verify against the following image to ensure it matches before proceeding

  

• Press Q key, a Save configuration prompt will appear, then press Y key
  
• Now the configuration should be saved and you should exit to the command line interface
• Enter the following command to start compilation, it may take some time

make -j4

• If the output is as follows, the compilation is successful

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

Enter Burning Mode

Tip

D7 models produced after September 1, 2024 have already been flashed with the Katapult firmware.

• Use a Type-C data cable to connect the main board to the host machine, then double-click the reset button, at this point there should be an LED light flashing on the main board.

Warning

• If there is no LED light flashing, please re-flash the Katapult firmware: Flash Katapult Firmware
• If there is no LED light flashing, please execute the next step after flashing the Katapult firmware.

Confirm Whether Entering Burning Mode

• Please ensure that the host machine can connect to the network normally and ensure that the data cable connecting the lower-level machine to the host machine has data transmission function.
• After SSH connecting to the host machine, input lsusb and press Enter. If the information circled in the following picture appears, you can proceed to the next step.
  • If there is no feedback at all, this is a system problem of the host machine, and we are unable to help. You need to replace with a confirmed normal system or replace the host machine.
  • If the prompt says there is no lsusb command, you can execute the following command to install it:

    sudo apt-get install usbutils

    
• 1d50:6177 belongs to the device you will use this time.
  • Some host machines may not fully display or fail to display due to system problems.
  • If the lsusb command can display the device but does not show 1d50:6177, please try replacing the data cable and connecting the mainboard to another USB port on the host machine.
• If you have executed the above steps before and successfully burned the Klipper firmware, and the mainboard is running normally, but you just want to update the Klipper firmware, please directly check the Firmware Update section in the right menu bar of this page.

Notice

You must query the 1d50:6177 device before proceeding to the next step.

Burn Firmware

tip

• When installing the programming plugin, you need to be connected to the internet. Please ensure that your host computer is already properly connected to the Internet.
• If it has been installed, there is no need to install it again.

Start Programming

Warning

• For non-fly host computers, please make sure to execute the following code to install the dependency package for firmware programming! Otherwise, the firmware cannot be programmed!

    cd && git clone https://github.com/Arksine/katapult.git

• Use this command to install in China

  cd && git clone https://gitee.com/MrCakeFuck/katapult.git

• Use the following instruction to search for your device ID, and the ID shown in the figure below should appear (note: the ID shown in the figure is for reference only, and each motherboard has a different ID):

  ls /dev/serial/by-id/*

  

• To program the firmware, use the following code, and make sure the firmware has been compiled successfully. Please replace <your motherboard ID> with the ID queried in the previous step.

  ~/klippy-env/bin/python ~/katapult/scripts/flashtool.py -d /dev/serial/by-id/<your motherboard ID>

For the fast system, use this command to program, please replace <your motherboard ID> with the ID queried in the previous step.

python ~/katapult/scripts/flashtool.py -d /dev/serial/by-id/<your motherboard ID>

• Below is a reference:

  

• After programming is complete, refer to the following:

  

Firmware Update

USB Firmware Update

• Use the following instruction to search for your motherboard ID, and the ID shown in the figure below should appear (note: the ID shown in the figure is for reference only, and each motherboard has a different ID).

  ls /dev/serial/by-id/*

Note

In the figure below, /dev/serial/by-id/usb-katapult_rp2040_E662549553642032-if00 is the motherboard's ID.

• To update the USB firmware, after compiling the latest firmware, enter the following command to update, please replace <your motherboard ID> with the ID queried in the previous step.

  cd ~/klipper/ && make flash FLASH_DEVICE=<your motherboard ID>

  

Bridge CAN Firmware Update

• To update the USB bridge CAN firmware, you need to enter the Katapult after compiling the latest firmware. Enter the following command (the ID in the figure below is for reference only, please use the ID in your configuration file).

Note

• <your CANBUS UUID> is the CANBUS UUID of the motherboard in your printer.cfg configuration file.

~/klippy-env/bin/python3 ~/katapult/scripts/flashtool.py -i can0 -r -u <your CANBUS UUID>

For the fast system, use this command to burn, please replace <your motherboard ID> with the ID queried in the previous step.

python3 ~/katapult/scripts/flashtool.py -i can0 -r -u <your CANBUS UUID>

Note

• In the figure below, f95cee90e1f9 is the motherboard's CANBUS UUID.

• After resetting into Katapult, use the following command to search for your motherboard ID, and the ID shown in the figure below should appear (note: the ID shown in the figure is for reference only, and each motherboard has a different ID).

  ls /dev/serial/by-id/*

Note

In the figure below, /dev/serial/by-id/usb-Klipper_stm32f072xb_43002C000951324757373520-if00 is the motherboard's ID.

• Make sure to execute the programming after the new firmware is compiled successfully. Please replace <your motherboard ID> with the ID queried in the previous step.

  cd ~/klipper/ && make flash FLASH_DEVICE=<your motherboard ID>

  

Solution for Incorrect Firmware Burning

• Power off the motherboard, power on again, and quickly double-click the reset button to re-enter programming mode.
• Or use the window/host machine to re-burn the katapult firmware burn katapult firmware
