Some of the stuff I have access to, I can open source, and some of it is protected under various agreements. I am tending towards taking a calculated risk. The best platform I am aware of today in terms of price/performance ratio is Allwinner H3 / H64. They do a pretty genius integration of components that are usuaully outside of the SoC into the SoC to reduce manufacturing compelxity, which in turn reduces the already low cost of a compute platform from Allwinner.
If I did that, the hardware design (PCB) can be open sourced, BUT the SoC will always (most likely anyway-- anything is possible, right?) have a highly encumbered GPU. The other caveat on the H3 platform (and the part that makes choosing this platform a calculated risk) is that the Ethernet driver is still being completed.
If the community, wants, I'll manage this as an open proejct and see it through. I'd really like to get feedback on the choice of SoC, here's what we've got to choose from, in general:
- Allwinner H3 (ethernet patch is in, YES!!!!!)
- Rockchip 3188
- Rockchip 3288 / 3688
- Intel Atom
.....with h3 being the cheapest of the three I've listed here. Personally, I am not restricted by any commercial agreements of any type. I can't give you the exact CPU specs, but no one can, and lucky for us the guys at Linux-Sunxi have gotten H3 working quite well, just like the guys at Linux-Rockchip have done 3188 and I think the guys at Intel and the core linux dev team have done for x86_64.
