i still have to write it up but i've discovered that it's possible to obtain PCB CAD files on taobao for the RK3288. with mike's help (and around $20) i've been working for the past 4 days on an EOMA68-RK3288 board. the RK3288 apparently supports up to 4GB of RAM, which is the primary reason why i'm looking at it at the same time as the nexell S5P6818 (which is 8-core but only does up to 2GB RAM).
the RK3288 was apparently designed for chromebooks, hence the increased RAM. what's nice is that i have the assistance of an engineer who works for rockchip, thanks to an introduction. i'll be arranging to go visit their HQ in a few weeks, to say hello.
The GPU seems very interesting. Supports OpenGL ES 3.2 and Vulkan 1.0.
Are all components supported under GNU/Linux (with proprietary drivers)?
honestly that's something i'm going to have to leave for someone else to investigate / answer, i've been non-stop for about 6 days on the PCB layout, it's one of the trickiest i've ever done as the 4 DDR3x16 RAM ICs are all on the TOP layer, leaving an absolutely ridiculously small amount of space left for routing, and i'm having to make some rather creative decisions on where to place some of the discrete components.
it's extremely taxing, very intensive, so i'm trusting that other people will answer software-related questions.
