Just an update, didn't actually receive this board until about May 2016 and have been battling on and off with this I now have an Armbian nightly build image (Ubuntu 16 - xenial based) with an arm64 rt-preempt patched 4.9.6 kernel which runs Machinekit. It was not simple, I had to write my own io.h, to be arm64 and pine64 specific to get the IO_BASE address right, with inline assembler code that arm liked and many more tweaks besides. But it is possible:) Latency - not too bad The GPIO is fairly basic, but works, so further experimentation to follow > > > Some of the Pine A64 developers have announced that they have linux > (specifically UBUNTU 14.04) > > booting on the A64.
