I have application with Two layers first layer for live video and the second for the gui. the camera buffer in external sdram and the gui in internal ram but i have pixel distortion in gui. what might cause it?

I have doubt that the bandwidth of the internal memory which is 1536MB/s is too fast. i am using stm32h743 at 480 MHz and the AXI bus speed is 240MHz.

So if it's not supported you need to create your own external loader.

To do so, you can refer to this document https://www.st.com/resource/en/user_manual/dm00403500-stm32cubeprogrammer-software-description-stmicroelectronics.pdf Section 2.3.3.

I believe what's written for TrueSTUDIO is the same for CubeIDE.
