Hi,

I have installed mt9v022 camera module on the IMX-53 QSB-LOCO and after modprobe I have this:

Thanks Jimmy for Your answer,

But test for camera is write for EVK and I want to port it for LOCO board. So I've allredy did modifs on LOCO.c (QSB) to have my camera up but i have had the error You've seen in the first mesg. I will do somme work to try to adapt the camera tests for the QSB_LOCO.

Thanks again.
