N6 DCMIPP CSI-2 Camera Struggles

[rphii]

Hi everyone,

I have a N6 Discovery Kit with a camera. Additionally, I have an N6 Nucleo Board. Now I want to use the CubeMX and CubeIDE to capture a frame on the Nucleo with the camera. I copied most of the things from the `DCMIPP_ContinuousMode` example but I still can't get it working...

• The I2C communication works (over I2C2)
• CAM_NRST => GPIO O5 get set to high.
• CAM_EN => GPIO A0 get set to high.
• Then I successfully call the IMX335_Probe(..)
• And finally, it fails here: https://github.com/rphii/STM32_N6_DCMIPP_MB1854B/blob/main/Appli/Core/Src/main.c#L137 (contains the full, minimal, reproducible code)
• I never get into the `HAL_DCMIPP_PIPE_FrameEventCallback`...

If anyone has more experience with the DCMIPP and CSI-2 (which is both new to me) and could help, it'd be greatly appreciated, thanks!
