Monitor can detect the signal as 1080p, but no display. Observed on:

Also observed on Origen Jelly Bean build:

Now monitor can't detect any signal at all. Please refer to attachment to get serial console boot log.

Now Origen board simply hangs after switch to HDMI display. Observed on Linaro Jelly Bean image:

Same behaviour observed as initial bug description on Samsung Origen board with Linaro Jelly Bean image:

https://android-build.linaro.org/builds/~linaro-android/origen-jb-gcc47-samsunglt-stable-blob/#build=47

No display comes out from HDMI although system doesn't hang any more.

Driver support is provided in the kernel. Need to add HAL layer code for JB.

Depends on https://bugs.launchpad.net/linaro-landing-team-samsung/+bug/1050336.

[Fahad Kunnathadi (fahad-k)]

Done Vendor source integration.
After integrating vendor source, and HDMI enabling code in JB, HDMI works on HDMI TV connected.
With kernel 3.4 .

When the Kernel is update to 3.6 or kernel tracking HDMI stops working.There is some issue in after kernel 3.5 rc.
which is propogated from the same bug in ICS ,
https://bugs.launchpad.net/linaro-landing-team-samsung/+bug/1050336
So origen board hangs, because of a V4L Bug.

[Botao (botao-sun)]

Unfortunately this feature still doesn't work on Linaro Android 12.10 release candidate. Please refer to attachment to get serial log output. It always show "unplugged" & "plugged", the monitor is black screen.

Botao,

HDMI works for me on 12.10 RC build #1 and this patch has been tested on Origen by Fahad. Can you please give a try once again.

[Botao (botao-sun)]

@Vishal, I tried twice yesterday, it didn't work on my board - the old Origen one. Since the Mini HDMI never works on my board, then perhaps we can check this issue when we meet next week.
