Hi again,
As you're using an MT9V032 sensor, I can help you with the pipeline setup. You
can run the following commands to capture 5 raw images.
./media-ctl -r -l '"mt9v032 2-005c":0->"OMAP3 ISP CCDC":0[1], "OMAP3 ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]'
./media-ctl -f '"mt9v032 2-005c":0[SGRBG10 752x480], "OMAP3 ISP CCDC":1[SGRBG10 752x480]'
./yavta -p -f SGRBG10 -s 752x480 -n 4 --capture=5 --skip 4 -F $(./media-ctl -e "OMAP3 ISP CCDC output")
When I use media-ctl the pipeline gets configured properly. I can
generate graphs before and after and see the pipeline change. However,
my system hangs when I attempt to use yavta. I've also tried outputting
to video4.
# ./media-ctl -p

Does anybody know how I can capture images from the camera? From
previous posts it appears that I'm not the first to go through this process.
Thanks. Neil
