1 hour ago, @lex said:
CAM500A needs to add some resistor to work with neo air.
There was an instruction on FriendlyArm to add this resistor to become CAM500B, but i can't find it right now.
I also feel there is another problem, I do not understand it
When I execute command ''make'' , the operation is not successful
Can you guide me where the problem is?

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.
