| 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/mmcblk0 bs=1k seek=1; sync |
| |
| - Flash the u-boot.img image into the micro SD card: |
| |
| sudo dd if=u-boot.img of=/dev/sdb bs=1k seek=128; 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. |
