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.

Hi,

Sorry for late reply. i disabled the cache which solved the problem.

I have another question. how can i Create a loader for parallel nor flash to store the assets there?
