Description Darren Hart 2011-07-19 17:09:03 UTC
Quote from Jeff Mitchell's problem report to the yocto list:

"
This is on a BeagleBoard xM rev C connected via its HDMI out to a DVI adapter and 
then into a Dell UltraSharp monitor. Angstrom doesn't display these 
problems, so the setup should be fine.

I'm not quite sure what is causing this. The resolution is also fairly 
low, and I haven't had any success using boot parameters (either the 
older video=omapfb:mode variant or the newer DSS2 omapfb.mode variant).
"

The terminal shows some red pixel noise along with cyan and white text overlapping eachother.

moving to accepted, but this is still pending triage by Darren.
Comment 2 Darren Hart 2011-08-18 14:42:32 UTC
Gary Thomas proposed a solution (kernel parameters) on a list. Jeff Mitchell was going to test, I haven't heard back in a few weeks though - we need to follow up with Jeff.
Comment 3 Bruce Ashfield 2011-08-22 20:12:09 UTC
Darren: has anyone followed up on this ? We've never seen this here.
Comment 4 Darren Hart 2011-08-24 13:46:46 UTC
Need someone with an xM rev C to test. I need to dig up Gary T's suggested kernel parameters.
Comment 5 Darren Hart 2011-09-06 07:31:42 UTC
Gary T's suggested display parameters:

"
I'm not sure where it came from, but I was using this mode
    dvimode=1024x768MR-16@60
The MR part seems to be causing the most trouble.  What I use now
quite successfully is
    dvimode=1024x768-24@60

Note: this is parsed as
   WWxHH-DD@RR
     WW - display width in pixels
     HH - display height in pixels
     DD - pixel depth
     RR - video refresh rate
"

Jeff is going to build and test, waiting on results.

Changing important, and release milestone. We still haven't reproduced this here, so we are largely waiting on this one to see if it has been addressed. 

We also have beagleboard 3.0 support that will be available soon, which would warrant a re-test.

No such problem and display well.
Comment 8 Bruce Ashfield 2012-01-04 06:41:59 UTC
The 3.0 kernel looks to address this, so I'm marking this as resolved.

Are you basing that on comment #7?

This suggests it was tested on Beagleboard C4. This is known to work. The bug was opened against the Beagleboard xM rev C (not the C4).
Comment 10 Darren Hart 2012-01-17 16:29:18 UTC
Please confirm this was tested on the Beagleboard xM rev C (not the Beagleboard C4).

C4 Boards ordered, but haven't arrived. Leaving as NEEDINFO as there is not a NEEDHW state.

Hi 
Are there any updates regarding this?

Thanks,
Alex.
Comment 14 Bruce Ashfield 2012-08-16 14:28:12 UTC
No updates, as I still don't have a xM rev C. Checking directly with the
Wind River yocto QA team is the best way to see if h/w arrived there.
Comment 15 Stoicescu Cornel 2013-02-13 15:02:14 UTC
Yi, can you please give us an update on this?
Comment 16 Yi Zhao 2013-02-19 06:05:05 UTC
No such issue with recent builds.

Test env:
beagleboard xM rev C
HDMI to DVI-D cable (I don't have a HDMI to DVI adapter)
Dell P2311H LCD monitor


I think we could close this bug.
Comment 17 Stoicescu Cornel 2013-02-19 09:09:36 UTC
Marking as RESOLVED as per previous comment.
Comment 18 Stoicescu Cornel 2013-02-19 09:10:02 UTC
