Thanks @RaptorSDS
I've extracted the dtb file from android image (kernel 3.10):
and from https://github.com/PabloCastellano/extract-dtb
So as my device is a 1gb i think that dtb should be 02_dtbdump_m8b_m201_1G.dtb
so I tried to booting using this dtb but without success.
I also decompiled and compiled again :
But it get stucked on Starting kernel ... with both dtb, extracted and recompiled.
So I think that I should build a dtb mixing from extracted android and meson8b-mxq.dtb that comes with armbian.
Thanks @balbes150 but my monitor supports 1080 (and this resolution works with android and alexelec firmware)
It should be something in dtb, I don't understand dtb files (yet).
do you know if it is possible to change to a newer generic u-boot , or u-boot is specific for each device?
Talking about wifi, it doesn't mind me, I only want to use ethernet and this works fine, but I asume that it should depend on dtb and linux loaded modules.
by the way, I tried to run docker (apt install docker.io because armbian-config don't install correctly docker) and It shows that /dev/mqueue doesn't exists:
thanks.
