how to upload program in external flash on stm32f746g-DISCOVERY?

[jsavy.1]

hi everybody,

I am working on a project with the stm32f746g-DISCOVERY board , I use Touch GFX to make a hmi.

The 1 Mbyte of Flash in the microcontroller is too short for my use

I am using keil to develop the project

if possible what setting do I need to change in keil ?

I hope somebody can help me (:

Redirect to "STM32 MCUs", "STM32F4" topics to be seen by relevant audience.

You'll want to use the QuadSPI (QSPI) external flash to hold large objects.

You'd enable the QSPI in the STM32 side software. ie clocks, pins, peripheral

You'd change the Target memory map to describe the 0x90000000 memory space to the linker.

You'd change the Debugger Option, Flash Download settings to Add the Flash Algorithm for the STM32F746G External QSPI Memory

Perhaps review/familiarise yourself with the examples

"STM32F7" would be better, I'd edit these things, but this forum software is broken
