+Buildroot for Embest RIoTboard
+==============================
+
+1. Compiling buildroot
+----------------------
+make distclean
+make riotboard_defconfig
+make
+
+2. Installing buildroot
+-----------------------
+Prepare an SD-card and plug it into your card reader. Create 2 partitions on the
+card using your favourite tool. Partition 1 should be around 32MiB, partition 2
+should be big enough to hold your rootfs:
+
+ Device Boot Start End Blocks Id System
+/dev/sdX1 2048 67583 32768 83 Linux
+/dev/sdX2 67584 329727 131072 83 Linux
+
+Format the partitions with your favourite filesystem:
+
+sudo mkfs.ext2 /dev/sdX1
+sudo mkfs.ext2 /dev/sdX2
+
+Copy the kernel and device tree blob on partition 1:
+
+sudo mount /dev/sdX1 /mnt/sdcard/
+sudo cp -v uImage /mnt/sdcard/
+suco cp -v imx6dl-riotboard.dtb /mnt/sdcard/dtb
+sudo umount /dev/sdX1
+
+Then deploy your rootfs on partition 2:
+
+sudo mount /dev/sdX2 /mnt/sdcard/
+tar xf rootfs.tar -C /mnt/sdcard/
+sudo umount /dev/sdX2
+
+3. Running buildroot
+--------------------
+Position the board so you can read the label "RIoTboard on the right side of
+SW1 DIP switches. Now configure SW1 swiches from left to right like this:
+
+10100101 (1 means ON position, 0 means OFF position)
+
+Now plug your prepared SD card in J6 SDcard slot. Connect a serial console
+(115200, 8, N, 1) to J18. Connect a 5V power supply to the board and break
+the boot sequence. Change your root device in U-Boot:
+
+setenv mmcroot mmcroot=/dev/mmcblk0p2 rw
+saveenv
+reset
+
+Enjoy!

This is a small development board, based on Freescale IMX6 Solo SoC (single core ARM Cortex-A9). The board has excellent support in mainline U-Boot and Linux.
