安装Installing Armbian on Rockchip RK3288 Android TV Box (M8S RK3288)

I love the idea of the Raspberry Pi, but there are some cheaper alternative single board computers that offer a similar experience for a fraction of the cost. While the community support isn't quite what it is for the Pi, there are a ton of projects you can accomplish on the cheap with these little hidden gems. Keep an eye on AliExpress and Amazon and you can find SBC's sporting quad core ARM process with 2-4 GB of RAM for under $30, including a power supply and IR remote control.

The box used in this video is a M8S (RK3288) I picked up on eBay for $15.99 shipped. It sports a Quad Core Rockchip RK3288 @ 1.8GHz and 2 GB of DDR3 RAM.

!! Warning !!

In order to get the RK3288 to boot to microSD you have to format the eMMC storage. This will remove the Android OS that came with the device. Make sure you have a backup of the Android image before proceeding in case you want to revert to Android in the future.
