Which models exactly are you suggesting we look into? The "Internet cube" project [1,2] uses the LIME and LIME2 boards: https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME/open-sou= rce-hardware https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXIno-LIME2/open-so= urce-hardware I think the only difference is the amount of RAM (512 MB vs. 1 GB) and the NIC (100M vs. 1G). The problem is that there is no onboard wifi, so you would have to use USB. > Do you know how the Ethernet is hooked to the SoC? I could be wrong, but > I don't think Allwinner SoCs include GMII. I suggest you look at the schematics (here for LIME2): https://github.com/OLIMEX/OLINUXINO/raw/master/HARDWARE/A20-OLinuXino-LIM= E2/A20-OLinuXino-Lime2_Rev_G.pdf Looking quickly, this looks like a SPI interface. I'm really not a hardware expert though, so you'd better check yourself. > Do they use upstream kernels, or their hacked up tree? I'm told that the kernel in Jessie supports the LIME/LIME2 since a few mont= hs. Before that, the Internet cube people where using the kernel from jessie-backports.
