+Wandboard
+=========
+
+The Wandboard is a carrier board available with three different
+System-on-Module options, the Wandboard Solo (i.MX6S, 512MiB DDR3),
+the Wandboard Dual (i.MX6DL, 1GiB DDR3) and Wandboard Quad (i.MX6Q, 2GiB DDR3).
+
+The device boots from the SD card slot on the System-on-Module board, it
+will not boot from the slot on the carrier board.
+
+To boot barebox on any wandboard, build imx_v7_defconfig
+and copy the barebox imx-image to the i.MX boot location of a SD card, e.g.
+dd bs=1024 skip=1 seek=1 if=images/barebox-imx6-wandboard.img of=/dev/mmcblk0
+
+Only one image exists, supporting all three Wandboard variants, barebox will
+detect the Wandboard variant depending on the SoC variant.
+This image is only usable for SD-boot. It will not boot via imx-usb-loader.
+
+Connect to the serial port using a null-modem cable to get console access.
+
+For further documentation, including board schematics see http://wandboard.org/
