This configuration should be valid for all F7 family devices in general. Here is the regions info: - Region0 : 4GB : cacheable & executable. - Region1 : 512MB : text area : strogly ordered & executable. - Region2 : 512MB : peripherals : device memory & non-executable. - Region3 : 512MB : peripherals : device memory & non-executable. - Region4 : 512MB : cortexM area: strongly ordered & non-executable. Higher region number overrides the lower region configuration.
