Re: OMAP 3430 Camera/ISP out of memory error

[Patrick Radius <info@notoyota.nl>]

Thanks,

I'm looking at
http://gitorious.org/linux-omap/mainline/trees/master/drivers/media/video

however, I can't seem to find the drivers I need.
I only see omap24xxcam while I was using the omap34xxcam from Linux
kernel 2.6.32.9.
And I also don't see any M-4MO driver anymore.
I'm probably looking at the wrong spot, but...

As you can tell, I'm fairly new with OMAP programming.

Thanks!

Regards,
Patrick
