Hi everyone.
I bought an ov5640 camera for my Nanopi Duo2. As their wiki clearly showed ov5640 plug and play, I thought I am facing no problems.
That's not the case. Armbian seems not to support ov5640 by defualt.
My problem:
OV5640 do not work on nanopi duo2 with latest armbian.
What did I try:
I searched for answers online, but they are old (years ago), saying I have to edit some dts files to get the cam work.
I tried some of them, then I messed up my system and have to re-flash the sd card again and again. I guess they might won't apply to the latest image.
I wonder:
Is the camera ov5640 on Nanopi Duo2 supported by armbian by default now?
If not, how exactly can I make it work?
Thanks for reading , looking for solutions.
