Re: Help required for TVP5151 on Overo
Hi Laurent, thanks for your reply... I'll disable device tree usage. Also, I'll try to use a previous kernel (3.17) hoping it works.

Help required for TVP5151 on Overo
Hello to everyone, I'd like to know who have used the TVP5151 video decoder with the OMAP3 Overo module. I'm trying to have the processor to capture the video from a TVP5151 boarda, but without success (both gstreamer and yavta wait forever the data from the V4L2 subsystem).

Re: Help required for TVP5151 on Overo
Hi Francesco, Yesterday I sent a mail asking about similar behaviour in another OMAP3 board [1], I'm starting to think that OMAP3 ISP is broken in latest kernel versions. I hope someone give us a solution.
