Bump up due to some news:
New Xenial image with mainline 4.14.68 kernel
New Xenial image with latest and greatest 4.18.6 dev kernel (which seems pretty stable to me)
Both new images now fully support the IR Remote out of the box, in native mode via kernel keymappings and drivers. Kernel keymap table can be customized using ir-keytable tool. Kernel 4.18.6 also exposes the native lirc interface, so in theory any remote controller can be trained to work with the box
Both new images enables the SPDIF connector (it is untested though due to lack of a Optical DAC at home)
Added devfreq support for the GPU: at the moment the base frequency is 100 Mhz and maximum frequency is 600 Mhz. The GPU may be too lazy to switch frequency, so you can force a minimum frequency issuing (as root) echo 300000000 > /sys/class/devfreq/devfreq0/min_freq to force the pre-devfreq default operating frequency. You may also force 600000000 (600 Mhz) as minimum to run the GPU always at full speed. Beware the thermals anyway, when the core reaches 70°C it starts throttling and your performance may not be as you expect if you don't cool enough the SoC
Every other thing which has been put into Armbian lately is also in the images
Enjoy!
