(Quit) > root@letux:~# Seem as if it tells me not much more than setting "pal" norm does fail and there is no "MUTE". VIDIOC_STREAMON is successful and the poll times out. Anyways, this indicates that the problem is probably not in the v4l2 layer but below, i.e. omap3isp+camera. Maybe as simple as the ISP ignoring the SYNC inputs and then of course failing to capture frames within given time. I have checked our pinmux setup but didn't find anything suspicious. So is it somehow possible to check if the omap3isp is running and receiving sync inpulses? BR and thanks, Nikolaus
