something interesting I saw is that in the update picking a processor, it shows rk3188 as the rockchip processor you were going to reverse engineer. on the other hand, your rhombus-tech link shows that your looking at rk3288?
Not to be annoying constantly, but I am curious are you looking at one or both?
just the 3288. the 3188 i considered but it's older, cortex a9 based so is *really* power-hungry. i got a dev board (ok an IPTV box), opened it up, immediately noted the heat-sink on the 3188 and went "absolutely not".
the 3288 on the other hand was the first commercial A17 (i believe) which is a sort-of uprated version of the Cortex A7 - something like that, anyway.
also it can do HDMI 2.0, 4k video playback (if you push the dual-channel memory up to a stonking 1600mhz that is...) and it kicks the stuffing out of the high-end variants of the intel atom.
more than that, its popularity in chromebooks has meant that the 3288 has a *lot* of modding and OS messing-about behind it. that's a good thing in that it's well-understood, but it does make it a f*****g nuisance to try and find decent instructions. i've given up on using google search and now go directly to #linux-rockchip on freenode. people there know what they're doing.
