How to use U-Boot on NXP i.MXRT1050 EVK
-----------------------------------------------
- Build U-Boot for i.MXRT1050 EVK:
$ make mrproper
$ make imxrt1050-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
- 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:
SW7: 1 0 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.
