There is an alternative way that allows you to update the firmware from the SD card in the bootloader:

Note: Flashing a bootloader for the wrong RAM configuration will cause your device to not start up properly anymore. Avoid doing that. If you do not know which firmware binary to flash ask for help.

• Hold <esc> in the terminal emulator of your choice (e.g. TeraTerm or PuTTY) while powering up the system with the WinPE SD card inserted in the device.

• The following series of commands will allow you to load the firmware binary from the SD card and write it to the boot partition 1 of the eMMC:

• Select the sd card socket

  Code Block
  mmc dev 1

• View the contents of the SD Card, verify that the firmware you want to write to the eMMC is present on the SD card

  Code Block
  fatls mmc 1:2

• Load the firmware binary you want to apply (In this example we use firmware.tr8m_v2r1.bin

  Code Block
  fatload mmc 1:2 0x40800000 firmware.tr8m_v2r1.bin

• Select the boot partition 1 of the eMMC

  Code Block
  mmc dev 0 1

• Write the firmware to the selected partition with the i.MX8M Mini specific offset

  Code Block
  mmc write 0x40800000 0x42 0x1B7B

• Select the eMMC Boot Partition as boot partition

  Code Block
  mmc partconf 0 1 1 0

• Erase the bootloader environment

  Code Block
  mmc env_erase

• Restart the device. It should reboot into the applied bootloader version.
  The first line of the serial output contains the build date of the bootloader.

  Code Block
  reset
