#f03c15 #c5f015 #1589F0 Flashing Firmware

When using any MCU with Klipper, it is important to first flash Klipper firmware. Follow these steps to flash your MCU with Klipper firmware:

Important

For MCU's using CANbus, follow this guide.

  1. SSH (PuTTy) into your Raspberry Pi

  2. Run the following commands:

    cd ~/klipper
make menuconfig

  3. Enter your MCU board's firmware settings, as explained later in this page.

  4. Save (Q)

  5. Run the following command:

    make flash FLASH_DEVICE=/dev/serial/by-id/<your-mcu-id>

Tip

To find your serial port, open a new SSH window, unplug your controller board, and run:

 ls /dev/serial/by-id

Next, plug in your controller board, and re-run the command. The newly added line is your controller's serial address.
