Another option might be an imx6 board since the Ethernet controller is not over USB and has PCIe for connection to an FPGA. So this could have the option of hm2_eth or hm2_PCI.
Another new board just announced is the ODROID-C2: http://www.cnx-software.com/2016/02/03/hardkernel-odroid-c2-64-bit-arm-development-board-to-sell-for-40-next-month/ http://forum.odroid.com/viewtopic.php?f=135&t=18683 $40 and includes integrated Ethernet vs over USB so maybe hm2_eth will "just work". It also has an ARM® Cortex®-A53(ARMv8) 2Ghz quad core CPU, ARM Mali™-450 MP3 GPU so it should be fast enough for a GUI since we had AXIS running just fine at HD res using software rendering on an older Cubie board (Cortex A9 1GHz) . We weren't even using LLVM pipe we were just using the software rasterizer. On 02/03/2016 08:34 PM, Chris Morley wrote: > > This is the point that many seem to miss.
