Hi, I built the vanilla jessie kernel (4.6.4) for my Orange Pi PC board with and without desktop but no joy in the HDMI display. My HDMI monitor screen was just blank while the red LED was blinking for an hour before I finally gave it up and powered off. Although there was no display, somehow the Ethernet port was working as it responded to the ping from my Windows laptop on command line "ping orangepipc.mshome.net". So the kernel building exercise was not at all in vain, and I guess Igor simply needs to fix the display driver issue and update here https://github.com/igorpecovnik/lib
My quest for the vanilla kernel was driven by the need to fix iw command under both jessie kernels 3.4.39 and 3.4.112-sun8i.
The problem I found was that whenever I typed "iw reg set GB" for example, followed by "iw reg get" the country was always country: 00 rather than country: GB. So I think this is a bug.
I was hoping that the vanilla kernel might fix this problem, but now it seems unlikely as I can't even get it to work let alone the freq/heat problem.
It would be great if there is a fix or a workaround to the iw problem.
Thanks
