+********************************************
+Buildroot for Engicam GEAM6UL SOM platforms:
+********************************************
+
+This file documents the Buildroot support for all Engicam GEAM6UL
+SOM platform boards.
+
+i.CoreM6 GEAM6UL SOM Starter kits:
+https://www.engicam.com/vis-prod/101115
+
+This configuration uses U-Boot mainline and kernel mainline.
+
+Build
+=====
+
+First, configure Buildroot for the Engicam GEAM6UL SOM:
+
+- for i.CoreM6 Quad/Dual:
+
+ make engicam_imx6ul_geam_mmc_defconfig
+
+Build all components:
+
+ make
+
+You will find the following files in output/images/:
+ - imx6ul-geam-kit.dtb
+ - rootfs.ext4
+ - rootfs.tar
+ - sdcard.img
+ - SPL
+ - u-boot-dtb.img
+ - uImage
+
+Create a bootable SD card
+=========================
+
+To determine the device associated to the SD 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 SD card. Launch the following
+command as root:
+
+ dd if=output/images/sdcard.img of=/dev/<your-sd-device>
+
+*** WARNING! This will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/engicam/genimage.cfg
+
+Boot the i.CoreM6 boards with SD boot:
+=====================================
+
+To boot your newly created system:
+- insert the SD card in the SD slot of the board;
+- connect 3-wire RS232 serial port J28 on board, and connect with other
+ serial end or USB cable(if serial-to-usb converter used) using
+ a terminal emulator at 115200 bps, 8n1;
+- close JM3 for sd boot.
+- power on the board.
+
+Enjoy!
