I had solved this problem by my friend. Run this script sunxi-pio -m "PG11<1><0><1><1>" modprobe gc2035 modprobe vfe_v4l2 The most import is that don't load gc2035 & vfe_v4l2 before. So you had better remove it in /etc/modules This is my /etc/modules #w1-sunxi #w1-gpio #w1-therm #gc2035 #vfe_v4l2 #sunxi-cir #v4l2loopback you may see /dev/video0, but when you reboot, it lose again I add my scrip to /etc/rc.local this is my /etc/rc.loca
