Other Parts Discussed in Thread: TVP7002

Hello,

I use DM816x with EZSDK 5.03. During the booting, the load-hd-v4l2-firmware.sh script is executed and I get the following

errors:

tvp7002 1-005c: TVP7002 read error -121
ti81xxvin ti81xxvin: Error registering v4l2 subdevice

After the booting, when I do lsmod I can see that all the modules were loaded,

omaplfb                10794  0

but I can't find the /dev/video0 device.

Can someone help me with that?

Thanks.

Just to rule out connectivity issues -- is the expansion I/O Daughter card (with the LCD connector & component video inputs) firmly connected?

The TVP7002's on that daughter card, and I ran into similar problems after removing and reinstalling the daughter card...turns out the connectors weren't fully mated.

Hi,

"tvp7002 1-005c: TVP7002 read error -121
ti81xxvin ti81xxvin: Error registering v4l2 subdevice"

Above error is coming becuase I2C master is not able to communicate with TVP7002. This normally happens when you daughter card is not inserted properly with the base board. Try removing and reconnecting the daughter card. It should work.

Thank you.

Indeed the problem was with the daughter card.
