A resonably fresh kit that supports HDMI ??

[Gullik]

Hi,

 

After bleeding edge 6.8 or so, I lost HDMI output. Does anyone run the recent kernels with HDMI? Which ?

The 6.1.75 kernel has HDMI, but a lacks Mt7961 wifi, and changing keyboard does not work, which

probably is my lack of understanding of wayland.

PS the HDMI issue might be a resolution thing, unfortunately I use an old TV ( 1920x1024)

Tried 6.11 rc edge?

Thank you Werner,

 

But, no luck, nothing on the monitor. I'll bring it down, connect uart and see what gives....

Same for me with 3 differents HDMI -> VGA converter, powered or unpowered.

 

I finaly fixe the problem :
# apt-get install read-edid edid-decode

# cat /sys/class/drm/card0-HDMI-A-1/edid > /tmp/test-edid.bin
# parse-edid < /tmp/test-edid.bin

Hmm, you have data blocks, but not video ones... weird

 

I have force the mode reported by the converter (or your HDMI screen) in /boot/armbianEnv.txt

In my case i add the line:

extraargs=video=HDMI-A-1:1280x1024@60
 

power off / wait few seconds / power on

OrangePi5+ boot in 6.10.6-current-rockchip-rk3588 and my video are back.

 

Regards,

JC
