Hello,
could anybody tell me the information of this code line
Stack_Mem SPACE USR_Stack_Size __initial_sp SPACE ISR_Stack_Size
Stack_Top
__initial_sp is the whole stack size - that's clear. But which information has the last code line Stack_Top? And why is the USR_Stack_Size in comparison to the other Stack_Sizes so big?
best wishes Tina
The user-stack is for your application, with all calls and auto variables.
The ISR stack is just for interrupt service routines, and they normally don't consume a lot of stack space - especially if you don't allow them to nest.
Have you spent some time reading up on the ARM architecture?
