emWin on STM32F7 and touchscreen
Hi,
I saw this answered on some other forum but can’t find the reference right now. Ivano is right about the debugger’s limitation to update the external memory.
The workaround is described at the end of the readme.txt file in the ST sample code. It is in “C:\STM32Cube\STM32Cube_FW_F7_V1.2.0\Projects\STM32746G-Discovery\Demonstration” on my PC, and essentially you need to download and use STM32 ST-Link Utility to upload a hex file (not .elf) to the board. Obviously you can use this technique for your own projects too 
Hope this helps.
