@balbes150 : May I ask about the sources for 3.10.108 kernel for S805 SoC? Maybe I missed something but there is only 3.10.33 in your Amlogic_s8xx-kernel repository, with last commit corresponding likely to your 20181124 release of Armbian image. However, for the better 20181207 build, I was unable to locate any sources or repository.
I have found out that this build (20181207) is almost perfect and it works flawlessly on the MXQ device (S805-V1.2 20150520). It is perfectly possible to move it into the internal flash and start it from there. But I was unable to install the slightly older one with 3.10.33 kernel; it does not work with the meson8b_mxq.dtb (hangs on boot) but starts with meson8b_m201_1G.dtb. I am asking because I am interested in doing some tuning on the kernel, more specifically on the video modes available.
