Subject: tvp5150: pxa27x-camera pxa27x-camera.0: Field type 9 unsupported.
Date: Tue, 20 Mar 2012 12:27:06 +0100 [thread overview]
Message-ID: <4F68698A.2070403@gmail.com> (raw)
Hello,
I am trying to run a tvp5150 driver with a PXA270 based board
I am using kernel version: Linux 2.6.35 armv5tel GNU/Linux
I also did a test with kernel-3.2.5 without success.
I started playing with V4L2, and I've never used it, but I built v4l2-utils.
The problem is something in pxa_camera_try_fmt() related to the settings
causing the error "pxa27x-camera pxa27x-camera.0: Field type 9 unsupported."

I am completely stuck at this, so I have some questions:
- is kernel version 2.6.35 good for using tvp5150 driver?
- do I need to have V2L to get out an image from tvp5150?
- which settings are missing in this driver?
- does anybody have seen a tvp5150 working with a PXA270 earlier?

Any hint would be greatly appreciated, if you need more details please ask.
TIA
