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

cam500a

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.

Here you have it:

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

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?
