I've recently been trying to set up an ov7725 on the csi 0 line.
I have it coming up and being recognized as a device.
However, when I try to get a picture out I get nothing.
I've used a couple different tests. but nothing gets a real response.
The output I have from /unit_tests/mxc_v4l2_overlay.out is
g_display_width=240, g_display_height =320
sensor chip is ov7725
sensor frame size is 640x480
sensor frame format is UYVY
frame_rate is 30
frame buffer width 1024, height 768, bytesperline 2048
Then about 3 seconds later I get a green pattern at the top of my screen.
My sensor by default puts out 60 frames per second (I have used i2c to control it down to 30 fps). It outputs in 640x480 in YUV format.
The driver I'm using is a clone of the ov3640 driver included with the BSP.
The big difference between the two drivers is that I have eliminated all the i2c set up data.
and replaced ov3640 with ov7725.
The main issue here is that I am not getting a picture. Could anyone offer suggestions?
