I am not able to open device node, fd_v4l = open(v4l_device, O_RDWR)
returns -1. I read documents and suspected that its read only. I tried
with that also it still does not work. (crwxrwxrwx 1 504
504 81, 0 Mar 12 2004 /dev/video0) is available in /dev. I have
less experience with Linux but I have used color conversions using v4l
in past. I was successful with framebuffer part. /dev/fb0 opens just ok
and all ioctls are working fine for framebuffer on the same board.

Subject: V4L on OMAP3
Hello,
We received OMAP3 board from TI. This has linux from mistral on this. There is
a node /dev/video0 on this but when I try to open this using O_RDONLY or O_RDWR
option, this does not open device. Is V4L functionality missing in this case?
We are using Linux version 2.6.22.1. We have registered our EVB on TI website
but there are no new updates for OMAP3503.
Thanks
Motra
