Hi Jon,


Il giorno 06/nov/2012, alle ore 00:21, Jon Hunter jon-hun...@ti.com ha 
scritto:

 I wanted to check the HDMI registers, but I didn't find the hdmi registers 
 table on the TRM.
 Does someone have some hint, comment or previous experience on that? 
 Where can I find the hdmi registers list on the manual or other 
 documentation?
 Note that as far as i know, the 2.6.35 kernel was working correctly (I can't 
 check right now, unfortunately).
 Thank you.
 
 I would recommend posting this query on the TI E2E forum for Linux [1].
 You may get better help there seeing that this is with regard to a
 specific TI development kernel branch.
 


Thank you very much for the suggestion! I'll post there.
Can you confirm that the kernel version I am using works without problem with 
HDMI-1080p? 
Thanks 
Cheers

Federico

Sorry, I have not tried. However, hopefully someone from the forum can help.

hdmi on 4430 (kernel 3.4)

2012-11-05 Thread Federico Fuga
Hi Everybody,

I am working on a custom OMAP4430 board with HDMI support. I am using the 
latest omapzoom ubuntu-integration kernel (3.4.0-1487.6) 
I tested the same on the pandaboard with the same cpu, with the same result. 
Both are lacking the HDMI Companion chip (U6 on pandaboard with 4430), 
because on our custom board we don't need EDID support (we are using an HDMI to 
VGA chip converter), for testing purpose it was removed from the pandaboard.
I am unable to make HDMI working. 
I was assured that this kernel is correctly working with HDMI on pandaboard, so 
I'd guess that the problem is due to the missing edid, but I am not 100% sure.
For simplicity, I removed the DVI configuration on the panda board file, by 
removing the DVI display configuration, and changing the default device to HDMI.
The hdmi interface seems to be configured correctly , the 
overlay/manager/display chain is correctly setup and enabled, but no signal is 
detected by the monitor, and the screen is black.
No errors are present in the logs - I'll send a copy of it with omapdss.debug=y 
tomorrow, eventually.
I wanted to check the HDMI registers, but I didn't find the hdmi registers 
table on the TRM.
Does someone have some hint, comment or previous experience on that? 
Where can I find the hdmi registers list on the manual or other documentation?
Note that as far as i know, the 2.6.35 kernel was working correctly (I can't 
check right now, unfortunately).
Thank you.

best regards

You need to contact your TI sales rep or tech support to sign an NDA
to get the HDMI documentation. Also, take note that your company
should be listed in HDMI.org in order the TI releases the said
document.
