将sonix的sn9c291+ov9712的驱动在rt5350加载成功后，产生两个节点，video0,和video1，但是会报下面的错误，暂时未做分析

# usb 1-1.2: new high speed USB device using rt3xxx-ehci and address 4

接下来运行demo程序

# ./SONiX_UVC_TestAP /dev/video0 -c -f mjpg -S

  将其中一张图片上传到tftp server查看下，
# tftp -l frame-000000.jpg -r frame-0000.jpg  -p 192.168.1.112

效果如下图，所capture时间为晚上，估计效果不太好。
