Hello,I am facing an issue while implementing USB UVC (Uncompressed) on the STM32U5G9J-DK2 board.The setup works fine with USBD_VIDEO_EPIN_HS_MPS set to 1400U, and I can achieve image output. However, increasing the endpoint packet size beyond 1400U ...

Thank you for your response!The original issue has been resolved, but I am now facing a limitation with the HS_MPS (High-Speed Maximum Packet Size) value.Currently, the HS_MPS is capped at 2044, and I need to increase it beyond this value to achieve ...

Thank you for your suggestions.We tried what you mentioned, and I can confirm that DMA is enabled, and we are using the HSE 32MHz clock for the PHY. We successfully sent a static frame buffer first without DCMI, which is working at 18 FPS with HS_MPS...

Thank you for your response!I prefer not to use linked lists for DMA, so I wanted to ask if it’s possible to use circular mode with standard request mode for DCMI with GPDMA. If circular mode is not supported without linked lists, could you suggest a...
