Update to my last post: I switched from the IDE's serial monitor (didn't work with A/E board ) to Putty, and now I have debug information. When running the sample file Snapshot, the camera is recognized and a picture is taken after 3 seconds, however, it will only find the camera when 640 x 480 image size is used, not the other two, and the image written to the sd card is empty (zero bytes).
Sample file MotionDetect will indicate the camera has been found, about 50% of the time, or it states "No camera found?". Same thing with the 640 x 480 image as mentioned above, and when it does claim to see motion, a file with zero bytes is written to sd card. For what its worth, "#define chipSelect 4" is being used.
