DM368 - Switching display from lcd to the component display

Akshita K A
Prodigy 110 points 
I'm working on the dm368 evm using DVSDK 4.0 and linux kernel version 2.6.37
The Board comes with an  LCD  and have connected a   720p component display to it.

After launching the matrix-ui launcher on the  LCD and when I try running the "decode" demo from the UI, I should be able to see the switching of matrix UI from LCD to component video. But In my case, I dont see a switch from the lcd to the component display nor do I get an output video played on component.
Even while running the demos from the command line , there appears to be no switch.

Bootargs used -
mem=60M console=ttyS0,115200n8 root=/dev/nfs rw nfsroot=192.168.1.179:/home/suma/Projects/DVSDK_4_02_DM368EVM/filesystem/rootfs ip=dhcp video=vpbe_fb:vid0=OFF:vid1=OFF
:osd0=480x272x16,4050K vpbe.def_output=Lcdout vpbe.def_mode=272p60 vpfe_capture.interface=1

I get the output on the component display only when the bootargs are set to the component display and when the matrix runs on the same.

There seems to be a problem while swiching the displays.
Can anyone help me in understanding how the display switching happens?
And also do I need to change my bootargs if I have to use any other display along with LCD?

The same set-up works fine with the 2.6.32 kernel.


Regards,


Akshita K A
