The most up-to-date kernel image is 4.9.119. Quite outdated already and most of the peripherals don’t work. HDMI Tx, HDMI Rx, secondary GMAC, PCIe 2 are not working. The support team is really slow with answer.
I am deeply disappointed with this SBC, none of the features that made me choose this board are working, and development seems to have stopped a long time ago.
Just wanted to start this thread and hopefully alert someone not to waste money on this hardware. Spend a little bit more and get a ODROID or other NAS SBC.
