+Meerkat 96
+==========
+
+The Meerkat96 is a single board computer based on an i.MX7D SoC by NXP,
+featuring a dual core ARM Cortex-A7 at 1 GHz and a Cortex-M4 at 266MHz
+and 512 MB DRAM. For further details on the board's features check the
+manufacturers page at https://www.96boards.org/product/imx7-96
+
+Serial console
+--------------
+
+UART6 of the i.MX7D is broken out to Pinheader J3, on the Silkscreen
+the Pins are labeled with B (Ground), W (UART 6 TX) and G (UART 6 RX).
+If you use the UART-To-USB-Converter provided with the board, you can
+just connect the Black jumper to B, the White to W and the Green to G.
+
+The UART uses 3.3V levels.
+
+Building Barebox
+----------------
+
+To build Barebox for the meerkat96 board do the following:
+
+.. code-block:: sh
+
+ make ARCH=arm CROSS_COMPILE=<ARM toolchain prefix> mrproper
+ make ARCH=arm CROSS_COMPILE=<ARM toolchain prefix> imx_v7_defconfig
+ make ARCH=arm CROSS_COMPILE=<ARM toolchain prefix>
+
+Bringup
+-------
+
+flash the resulting barebox-meerkat96.img to an sdcard at address 0.
+
+Make sure the pmic is set to power-on state by setting the dipswitch
+SW3 on the boards bottom side to 1-1 (i.e. all switches on, which is
+the factory default).
+
+Schematics
+----------
+
+Schematics are available at https://github.com/96boards/documentation/blob/master/consumer/imx7-96/hardware-docs/files/iMX7-96-schematics.pdf
