Hi,
 
We are facing below issue in OV5640 camera sensor module. When we continuously run the overlay, some of the time overlay is not working. I would like to say, we are facing inconstant issue in OV5640 camera sensor. The OV5640 camera module run with Embedded sync format. Do you have any idea why this inconsistent issue occurring in OV5640 ?

Any timing parameter to be changed ?
 
Please help us.
 
Regards,
Mohammed Azlum

Hi Mohammed

one can check Release Notes of used BSP, for example

in attached sect.6.3 Known issues and limitations for multimedia.

Other options to narrow down issue may be descreasing processor bus

loading or increasing cma size.

Best regards
igor
