Please refer to the QSPI example provided in STM32CubeH7.

This Application Note AN4760 provides detailed information on the Quad-SPI interface on STM32 microcontrollers and microprocessors. It includes examples and guidelines for configuring and using the QSPI interface for executing code from external flash memory.

Hey AnoopYadav,

I'm having the same issue. I'm trying to get one of my NUCLEO-STM32H7S3L8 boards to run with some simple LED blinking software, but nothing works. The STM support only points to some entirely irrelevant samples. I can't even download the software to the board. There's no usable documentation about those MCUs.

I gave up on those boards and went back to use the STM32H723 and STM32H763 MCUs. Maybe some day STM is able to come up with some usable documentation.
