+How to use U-Boot on NXP i.MXRT1170 EVK
+---------------------------------------
+
+- Build U-Boot for i.MXRT1170 EVK:
+
+  .. code-block:: bash
+
+      $ make mrproper
+      $ make imxrt1170-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
+
+  This location is not compatible with GPT partioning. Please, use MBR
+  partitioning instead.
+
+- 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
+
+  .. list-table::
+     :stub-columns: 1
+
+     * - SW1
+       - 1 0 1 0
+     * - SW2
+       - 0 0 0 0 | 0 0 0 0 | 1 0 0 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.
