Could you please provide more explanation on your case, so that it will be easier to understand the issue?

I guess you'd need to ask yourself why you needed them in the first place? Your use case is highly application specific and the question lacks salient context. Review the manuals to determine the available RAM and FLASH regions and expand and contract your allocations here based on the speed and sector sizes that most optimally address your use case.

Hi

ELMHIRI.Syrine

we want to migrate from stm32f4 to stm32f7 , and so we should to modify the scatter file to configure the new mapping in stm32f7

#! armcc -E
