Hi Nagabhushana,

Thanks for the quick reply.  i am looking for a DM368 interfaced sharp/any lcd driver source, So that i can have it as a reference and modify the code for the new lcd module. can you please point me the exact link.

Thank you.

I believe all it needs is d368 VPBE being programmed to send appropriate timings to LCD.

You can refer to arch/arm/mach-davinci/board-dm365-evm.c and

drivers/media/video/davinci/vpbe_venc.c

Hi Nag,

Thank you very much. vpbe_venc.c i could not find in the kernel(2.6.32) which i am working there is one file vpbe_encoder.c. seems both are same.

for lcd display we need to work with the encoder files?

Thank you.

Hi Nag,

The display interface is Parallel RGB with the DM368.

Sreedhar,

Branch I shared with you is of Kernel version 2.6.37. 480x272 sharp LCD panel which comes with dm368 EVM works fine with that driver. You can take that as reference for making your LCD work with dm368. In case of 2.6.32, looks like you need to change vpbe_platform.c

Hi Nag,

I found the link, thank you. i understand that the changes done in the below files.

1. arch/arm/mach-davinci/board_dm365_evm.c ,

2. arch/arm/mach-davinci/dm365.c and

3. arch/arm/mach-davinci/include/mach/mux.h file

drivers/media/video/davinci/

vpbe.c  , vpbe_display.c ,  vpbe_venc.c , vpbe_types.h , vpbe_venc.h

Please correct me if i am wrong in understanding.

One more thing in which kernel version these files are available.

Thank you.

Your understanding looks fine to me. I believe the branch I referred to is 2.6.37.

Hi Nag,

I could not find in 2.6.37 stable release.

Can you please check and tell me in which version it is available.

I am just suggesting you to refer http://arago-project.org/git/projects/?p=linux-davinci.git;a=shortlog;h=refs/heads/03.21.00.05 for LCD output implementation. You can implement your solution on any version you are aiming for.
