Firmware download link is fixed, thank you :slight_smile:

If you want to recovery bootloader, either:

  • Flash the whole image again:
    sudo upgrade_tool uf /path/to/update.img

  • Update the bootloader
    sudo upgrade_tool DB /path/to/loader.bin # this download the loader to the board
    sudo upgrade_tool UL /path/to/loader.bin # this shall upgrade to loader of the board
