Hello,
I want to use external SDRAM as the LTDC framebuffer with the STM32F746 microcontroller. I can write and read the desired data to/from the SDRAM without any issues. However, when I activate the LTDC, during the SDRAM initialization and configuration settings, I suddenly encounter a "target is not responding" error. After this, the microcontroller becomes completely unresponsive. The only way to recover it is to set it to boot mode and erase the entire flash memory.
What could be the problem here?
I appreciate your help.
Thank you.
