It costs EUR 45, and has 160 GPIO pins. This is a guide to build a linux image with Debian and the mainline 4.0.0 kernel for the Olimex A20-Lime2 board, from scratch. By default it comes with an 3.4 kernel with binary blobs and patches from Allwinner. Recently the mainline kernel has gained support for these boards, you can now run and use the mainline kernel without these awfull non-free binary blobs.

It costs EUR 45, and has 160 GPIO pins. The default Debian image from OlimeX is quite huge and bloated, over 2,5 GB, with X and all. I do not want a huge image, so I stripped it down to a 200 MB image with only dhcp and ssh and a few basic tools. It uses about 15 MB of RAM. This image allows you to start with almost nothing and build up only what you need. Wed, 28 Jan 2015 00:00:00 GMT Wed, 28 Jan 2015 00:00:00 GMT
