I'm getting a V4L failure on our custom DM6467 board in MCVIP_v4l2Create(). The input enumeration shows a "TVP5158" input, but I get "Remote I/O error" when it tries to select this input in the VIDIOC_S_INPUT driver call. The log does show that it reads the correct TVP5158 chip ID in TVP5158_checkChipId(). So, I think the I2C bus is ok.
Any ideas on what the problem is? I have included the boot output as well as output from our app.
Thanks
