+OMAP5432 uEVM
+=============
+
+This file documents the Buildroot support for the OMAP5432 uEVM[1], a
+single-board computer development platform based on the Texas Instruments
+OMAP5432 system on a chip (SoC).
+
+How to build
+============
+
+  $ make uevm5432_defconfig
+  $ make
+
+How to write the SD card
+========================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+  $ sync
+
+Where /dev/sdX is the device node of your SD card (may be /dev/mmcblkX instead
+depending on setup).
+
+To boot from SD card, set the SYSBOOT switches S1 of your OMAP5432 uEVM to the
+following position:
+
+  ON   x   x
+     x   x
+     1 2 3 4
+
+Insert the micro SDcard in your OMAP5432 uEVM, and power it up with the POWER
+ON push button switch S3. The console is on the micro USB Debug UART, with
+serial settings 115200 8N1. Refer also to the quick start guide[2].
