| 6 | How to use U-Boot on NXP i.MXRT1170 EVK |
| 7 | --------------------------------------- |
| 8 | |
| 9 | - Build U-Boot for i.MXRT1170 EVK: |
| 10 | |
| 11 | .. code-block:: bash |
| 12 | |
| 13 | $ make mrproper |
| 14 | $ make imxrt1170-evk_defconfig |
| 15 | $ make |
| 16 | |
| 17 | This will generate the SPL image called SPL and the u-boot.img. |
| 18 | |
| 19 | - Flash the SPL image into the micro SD card: |
| 20 | |
| 21 | .. code-block:: bash |
| 22 | |
| 23 | $sudo dd if=SPL of=/dev/sdX bs=1k seek=1 conv=notrunc; sync |
| 24 | |
| 25 | This location is not compatible with GPT partioning. Please, use MBR |
| 26 | partitioning instead. |
| 27 | |
| 28 | - Flash the u-boot.img image into the micro SD card: |
| 29 | |
| 30 | .. code-block:: bash |
| 31 | |
| 32 | $sudo dd if=u-boot.img of=/dev/sdX bs=1k seek=128 conv=notrunc; sync |
| 33 | |
| 34 | - Jumper settings |
| 35 | |
| 36 | .. list-table:: |
| 37 | :stub-columns: 1 |
| 38 | |
| 39 | * - SW1 |
| 40 | - 1 0 1 0 |
| 41 | * - SW2 |
| 42 | - 0 0 0 0 | 0 0 0 0 | 1 0 0 0 |
| 43 | |
| 44 | where 0 means bottom position and 1 means top position (from the |
| 45 | switch label numbers reference). |
| 46 | |
| 47 | - Connect the USB cable between the EVK and the PC for the console. |
| 48 | The USB console connector is the one close the ethernet connector |
| 49 | |
| 50 | - Insert the micro SD card in the board, power it up and U-Boot messages should come up. |
