Hi Pratap,
We had applied pinmux patch to kernal to play the audio then we had recompiled the kernal and built the new U-boot image.
Now ones the board boots up I have following modules loaded. we have pvrsrvkm, drm, syslink,vpss,hdmi,fb., omaplfb modules.
Later I am running pvr-init stop. So at that time all the pvr related modules are unloaded as shown below.
pvrsrvkm 155618 0
tlc59108 1545 0
ti81xxhdmi 17685 0
ti81xxvin 20591 0
tvp7002 6429 0
ti81xxvo 21210 0
ti81xxfb 21979 0
vpss 74936 4 ti81xxhdmi,ti81xxvin,ti81xxvo,ti81xxfb
syslink 1133911 0
Then I am trying to do depmod -a and followed by that I use to 38xx demo script.
then at the end he will through no screens found error message.
Now If I start the matrix gui then if I run the demo script X- server will launch successfully but if I do lsmod drm module is not loaded.
If I do modprobe drm it will be loaded.
/usr/local/XSGX/var/log/Xorg.0.log this log shows drmopendevice failed message.
So as a whole I am not able to run X-app.
I had followed most of the links shared by you.
Now I need to try by unloading module by default during boot-up and follow the steps shared by you. Have to see whether it will work or not.
Thanking You ,
Ashwath
