Reinstalling STM32F745G-DISCO Demo
The only problem is that the debugger (gdb+openocd) cannot program the content located within the external flash memory.
Otherwise when debugging your application (after loading the hex using ST-LINK UTILITY) you can disable the programming step (Debug Configurations > $Your_Config$ > Startup ⇒ uncheck ‘Load image’ checkbox), so the debugger will connnect to your device without reprogramming the application.
If you want to display the external memory content, this is possible if the external memory is initialized.
In other words: you can read the external memory content after your application initializes the external memory.
