How to use U-Boot on NXP i.MXRT1170 EVK

  • Build U-Boot for i.MXRT1170 EVK:

    $ make mrproper
    $ make imxrt1170-evk_defconfig
    $ make

    This will generate the SPL image called SPL and the u-boot.img.

  • Flash the SPL image into the micro SD card:

    $sudo dd if=SPL of=/dev/sdX bs=1k seek=1 conv=notrunc; sync

    This location is not compatible with GPT partioning. Please, use MBR partitioning instead.

  • Flash the u-boot.img image into the micro SD card:

    $sudo dd if=u-boot.img of=/dev/sdX bs=1k seek=128 conv=notrunc; sync
  • Jumper settings


    1 0 1 0


    0 0 0 0 | 0 0 0 0 | 1 0 0 0

    where 0 means bottom position and 1 means top position (from the switch label numbers reference).

  • Connect the USB cable between the EVK and the PC for the console. The USB console connector is the one close the ethernet connector

  • Insert the micro SD card in the board, power it up and U-Boot messages should come up.
