Hello,

By default in ezsdk we are using tvp7002. You should add tvp5150 drive in the kernel build the ko module.

You should hook this up to the v4l2 capture driver as well.
Check this user guide:
processors.wiki.ti.com/.../DM81xx_AM38xx_Adding_External_Decoders_to_V4L2_Capture_Driver

You also could check this topic.

Hello,

I would recommend you to check in my previous post the both links.
In lsmod I do not see the .ko module for tvp515 to be loaded. I see only tvp7002.ko.
