  1. hi I am grateful for the help that will be given to me. Please help me with the launch of the cam500a by Nano Air. I tried to use http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO_Air#Connect_to_DVP_Camera_CAM500B guides and go along with it.  but I did not succeed . I am very beginner and need help.  This is all that I get by following the guide http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO_Air#Connect_to_DVP_Camera_CAM500B. What should i do

  3. Is cam500a the only problem? Is the problem resolved by changing it to cam500b? There is no way to answer the cam500a? Thank you very much for your directions
