+***************************
+Freescale i.MX6UL EVK board
+***************************
+
+This file documents the Buildroot support for the Freescale i.MX6UL EVK board.
+
+Please read the i.MX6UL Evaluation Kit Quick Start Guide [1] for an
+introduction to the board.
+
+Build
+=====
+
+First, configure Buildroot for your i.MX6UL EVK board:
+
+ make freescale_imx6ulevk_defconfig
+
+Build all components:
+
+ make
+
+You will find in ./output/images/ the following files:
+ - imx6ul-14x14-evk.dtb
+ - rootfs.ext2
+ - rootfs.tar
+ - sdcard.img
+ - u-boot.imx
+ - zImage
+
+Create a bootable microSD card
+==============================
+
+To determine the device associated to the microSD card have a look in the
+/proc/partitions file:
+
+ cat /proc/partitions
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on a microSD card. Launch the following
+command as root:
+
+ dd if=./output/images/sdcard.img of=/dev/<your-microsd-device>
+
+*** WARNING! This will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/freescale/imx6ulevk/genimage.cfg.
+
+Boot the i.MX6UL EVK board
+=========================
+
+To boot your newly created system (refer to the i.MX6UL EVK Quick Start Guide
+[1] for guidance):
+- insert the microSD card in the microSD slot of the board;
+- verify that your i.MX6UL EVK board jumpers and switches are set as mentioned
+ in the i.MX6UL EVK Quick Start Guide [1];
+- put a micro USB cable into the Debug USB Port and connect using a terminal
+ emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enjoy!
