Video Port Access via DSP on OMAP3530

Hi Vallabha,

I can not comment on DSP part but definately I can help you on ARM-Linux side, you can find the driver for whole DSS for ARM-Linux under <linux home>/drivers/video/omap2/dss/

In case you are not aware of Linux architecture you can refer to the link pointing to above location

Hello Vaibhav,

Where can I find the defs for the structure(s) omap_video_timings and omap_dss_device?

What is the YUV format required to display the video on composite port of omap3530?

Hi Vallabha,

You can find the definition inside

http://arago-project.org/git/projects/?p=linux-omap3.git;a=blob;f=arch/arm/plat-omap/include/plat/display.h;h=c66e464732df1e33c24d068c3b7c4eca40760306;hb=8d78b8198d220d5ebade7587caf664a0ef8c8fe7

And for supported YUV pixel format over video plane, please refer to the TRM section 15.4.2.3.1 Video Memory Formats OR you can also refer the PSP user guide http://processors.wiki.ti.com/index.php/UserGuideDisplayDrivers_PSP_03.00.00.04#Buffer_Format

Thanks,
