+
+How to use U-Boot on Freescale MX6UL 14x14 EVK
+-----------------------------------------------
+
+- Build U-Boot for MX6UL 14x14 EVK:
+
+.. code-block:: bash
+
+   $ make mrproper
+   $ make mx6ul_14x14_evk_defconfig
+   $ make
+
+This will generate the SPL image called SPL and the u-boot.img.
+
+1. Booting via SDCard
+---------------------
+
+- Flash the SPL image into the micro SD card:
+
+.. code-block:: bash
+
+   sudo dd if=SPL of=/dev/mmcblk0 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/mmcblk0 bs=1k seek=69 conv=notrunc; sync
+
+- Jumper settings::
+
+   SW601: 0 0 1 0
+   Sw602: 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 push buttons
+
+- Insert the micro SD card in the board, power it up and U-Boot messages should come up.
+
+2. Booting via Serial Download Protocol (SDP)
+---------------------------------------------
+
+The mx6ulevk board can boot from USB OTG port using the SDP, target will
+enter in SDP mode in case an SD Card is not connect or boot switches are
+set as below::
+
+   Sw602: 0 1
+   SW601: x x x x
+
+The following tools can be used to boot via SDP, for both tools you must
+connect an USB cable in USB OTG port.
+
+- Method 1: Universal Update Utility (uuu)
+
+The UUU binary can be downloaded in release tab from link below:
+https://github.com/NXPmicro/mfgtools
+
+The following script should be created to boot SPL + u-boot-dtb.img binaries:
+
+.. code-block:: bash
+
+   $ cat uuu_script
+     uuu_version 1.1.4
+
+     SDP: boot -f SPL
+     SDPU: write -f u-boot-dtb.img -addr 0x877fffc0
+     SDPU: jump -addr 0x877fffc0
+     SDPU: done
+
+Please note that the address above is calculated based on SYS_TEXT_BASE address:
+
+0x877fffc0 = 0x87800000 (SYS_TEXT_BASE) - 0x40 (U-Boot proper Header size)
+
+Power on the target and run the following command from U-Boot root directory:
+
+.. code-block:: bash
+
+   $ sudo ./uuu uuu_script
+
+- Method 2: imx usb loader tool (imx_usb):
+
+The imx_usb_loader tool can be downloaded in link below:
+https://github.com/boundarydevices/imx_usb_loader
+
+Build the source code and run the following commands from U-Boot root
+directory:
+
+.. code-block:: bash
+
+   $ sudo ./imx_usb SPL
+   $ sudo ./imx_usb u-boot-dtb.img
