=============
How to use U-Boot on NXP i.MXRT1020 EVK
---------------------------------------
- Build U-Boot for i.MXRT1020 EVK:
.. code-block:: bash
$ make mrproper
$ make imxrt1020-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:
.. code-block:: bash
$sudo dd if=SPL of=/dev/sdX bs=1k seek=1 conv=notrunc; sync
- Flash the u-boot.img image into the micro SD card:
.. code-block:: bash
$sudo dd if=u-boot.img of=/dev/sdX bs=1k seek=128 conv=notrunc; sync
- Jumper settings::
SW8: 0 1 1 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.
