Control Board Firmware (For the SKR)

Pre compiled firmware

  1. Use a blank SD card, formatted as FAT32 (FAT MSDOS)

  2. Download the firmware

    Binary:

    firmware.bin

  3. Put the file on the top of the SD card, and make sure no other file is on the SD card.

    Do not rename the file, it needs to be named firmware.bin.

    Untitled

  4. Power down the main board

  5. Insert the SD card into the SKR board

  6. Turn it on and wait a minute, it will blink for a few seconds

  7. Done! (You don’t need the SD card anymore, you can remove it)
