STM32H7 + OV5640: unable to capture any images

[Robi7]

Hi!

I am working with a stm32h743zit6 + ov5640 combo. I am using STM32CUBEMX + Makefile on Ubuntu.

Currently I am at the state of:

- Camera setup is successful
- Code gets into HSYNC event callback

- Code gets into VSYNC event callback

- Code doesn't get into Frame event callback

Currently I am unable to capture any images. I would really appreciate your help!

Thank you in advance!

See my reply (and possibly discussion) in the STM32World discord server (https://discord.gg/Dupk5VA2), where you also requested the "active" community to assist.
In short; Sending the notifications over a slow, blocking uart, is likely to cause disruption in the library. My guess is that the library detects that not all lines have been processed correctly, considers the frame corrupted and doesn't send the frame event.
