External QSPI flash storage in STM32F746ZGTx rather than STM32F746 Discovery Board

[Chandan Bhatia1]

Hello, I am able to store data External QSPI flash storage of  STM32F746 Discovery Board using given external loader N25Q128A_STM32F746G-DISCO with STM32 CubeMx programer.

Now in my project I am using different package STM32F746ZGTx ( LQFP144 (20x20 mm) ) . I am not sure if same given external loader will work or should I need to create my own loader.

Can any one explain How exactly external loader work ? It will making QSPI in indirect mode to store data data.

The external loader facilitates access to the unique memory and board specifics. Provides simple API to read, write, erase, etc.

Your choice of memory IC and pins/wiring will dictate if an existing loader can be used, or if you need one tailored to your different design choices.​
