Spain >+34 942 25 32 60 >www.vista-silicon.com I've been finally able to attach the ov2640 camera in the i.MX25PDK. I've had some problems with the clocks, but a quick dirty fix looks to solve this issue (I'll work on cleaner solution later). Now I have to send the camera stream to "somewhere". In the example provided by Freescale based on L2.6.31, "somewhere" is the framebuffer, and this is done using VIDIOC_S_FBUF and VIDIOC_OVERLAY ioctls. As these 2 ioctls are not currently implemented in soc_camera.c, I was wondefing if it exist a different preferred method to implement this functionality?
