Have you this message? Anyway, there is a problem with the EDID: - my Orange Pi 2 (H3) randomly fails to read it. But this succeeds after rebooting once or twice. - my Banana Pi M2+ (H3) reads it correctly each time. - my Banana Pi M3 (A83T) can never read it. BTW, on first tries, I was forcing a CEA mode thru the kernel command line. This was working with the OPi2 and BPiM3, but there was no sound. In the last version, I use a EDID in edid_firmware for having sound with the BPiM3. This works fine. But, forcing a CEA mode is no more possible, so, when the OPi2 cannot read the EDID, the system switches to a VGA mode (default 1024x768) which is not supported. It seems that this is your case. So, in brief, if your board cannot read the EDID, put a EDID somewhere and its path in /sys/module/drm_kms_helper/parameters/edid_firmware. There will be no console, but X11 will work correctly. -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/ -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
