Hello St community !
for now i'm trying to build a project based on the nucelo-N675-Q board. I'm trying to interface an STEVAL-66GYMAI1 camera and plot 2 frames values into the terminal . I'm building my project based on this repo https://github.com/supungamlath/STM32N6_Survivor_Detection . I made sure to copy the middlewares for my specific sensor but i'm finding that the camera camera never streaming a real data based on the debugging and getting an callback error on line 1

Thank you !

Hi @whoami 

This looks more like an integration issue than a hardware issue.

Also, the attached project doesn’t seem to compile correctly as is, so it’s hard to check with you the camera streaming path end to end.

Based on the log, the sensor init starts, but then the CSI capture hits an error, which usually points to something in the board setup, sensor middleware integration, or camera pipeline config.

I’d suggest first narrow down the issue and provide minimal project, then checking the camera setup step by step with a minimal capture example before adding the rest of the application back.
