Resetting all links...
the video input is CVBS IN,it just can not allocate memory and Error in opening display device.
also i try saMmapLoopback,and it failed to open /dev/v4l-subdev9.
how can i fix it? i boot from the SD card ，MLO u-boot.img and uImage in the partition 1,and the FS (targetNFS in the SDK) in the partition,type is ext3.
thanks
