Hello,

 

I have the following hardware setup:

cm-bf561, evaluation kit and camera extender board from bluetechnix. camera: ov7670 and ov2640

 

Software setup:

uclinux distribution: 2011R1-RC3.

menuconfig set up as per http://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:v4l2_blackfin_capture

Did settings as per the above link for ov2640

 

Problem:

No video0 device is created after modprobe bfin-video-capture

 

How should I get the v4l2 to work and grab an image?

 

Also I tried to port v4l1 from 2010 distribution, but that gives a memory exception while trying to grab an image.

Is the v4l previous framework compatible with the new kernel?
