Before start

Building AOSP(Android Open Source Project) for radxa rock is a huge task, it takes a lot of time and disk space. You can read the detail requirement of the machine on AOSP requirement page. The recommend building OS is Ubuntu 12.04 64bit. It takes about 35 minutes and 30G disk space on a intel 4770 processor(i7, quad core, 3.4Ghz) machine with 16G ram and SSD.

Build the kernel

Build android source code

Generate the image

   ./mkimage.sh ota

you will get boot.img recovery.img system.img under rockdev/Image, and update.img under rockdev

Flash the image

Next, follow the flash to NAND flash to flash the image to NAND flash you just build.
