Environment: (H2+) + linux-sunxi + ov5640 

 

 It can be registered by kernel ,but I can't capture any picture from camera .

 

Here is my kernel demsg:

How can I fix it ?

Providing logs with 

armbianmonitor -u

 helps with troubleshooting and significantly raises chances that issue gets addressed.
