Issue with MX_JPEG_Init Blocking on STM32N6DK750

[HMTb]

Hello,

I’m trying to add the JPEG encoder to be able to save images in JPEG format to the SD card.

While debugging with LEDs, I noticed that MX_JPEG_Init blocks the program, whereas HPDMA is working correctly.
I have added all the necessary files for JPEG, but it doesn’t seem to activate.

Interestingly, when I disable MX_JPEG_Init, I can see the images on the screen connected to the board without any issue.

I’m wondering if there is a configuration problem with the JPEG or if I’m missing something.

For reference, I’m using the STM32N6 Discovery Kit (STM32N6DK750).

Thanks for any advice!

Hi @HMTb 

Do you reproduce using the provided firmware here?

[HMTb]

Hi, yes, I cloned the repository with all submodules recursively to make sure nothing was missing. Then I started modifying the DCMIPP snapshot project to add JPEG support.

@HMTb  I would suggest to test the example JPEG_EncodingFromOSPI_DMA as it is and see if the issue persists.
