| How to use U-Boot on NXP i.MXRT1050 EVK |
| --------------------------------------- |
| |
| - Build U-Boot for i.MXRT1050 EVK: |
| |
| .. code-block:: bash |
| |
| $ 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: |
| |
| .. 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:: |
| |
| 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. |
