Hello @Aryan_vats_15 and welcome to the community;

 

You can use the OCTOSPI interface to connect the external memory.

I recommend you to refer to AN5050 precisely section 7 OCTOSPI application examples and get inspired to configure W25N01GV.

Also, I think STM32CubeH5/Projects/STM32H573I-DK/Examples/OCTOSPI at main · STMicroelectronics/STM32CubeH5 · GitHub examples can help you.

 

Thank you.
