How can I determine the starting address of the stack in CubeIDE?

In Keil, if you open a file with the extension .map, you can find information about starting address of stack and so on. See screen.

How can I determine the starting address of the stack in CubeIDE?

Hello,

Go to STM32CubeIDE\Debug and open .map file. Try to find the line

_estack = (ORIGIN (RAM) + LENGTH (RAM))

 

[DK.7]

Thanks for the answer!

I found the desired line in .map file

 

_estack = (ORIGIN (RAM) + LENGTH (RAM))

 

and I don’t understand what to do with it. See screen.

Thank you, but how to find out the end address of stack from this file?

[mƎALLEm]

_estack defines the end of the Stack which is the Top of the stack.

So normally the stack starts at: _estack - _Min_Stack_Size

It should really use the space allocated by the linker, in this case ST just lets it descend into the end of the heap

See _sbrk implementation in syscalls.c

ST sets in to the end of RAM, and it auto-decrements from there, basically the first 32-bit word gets stored at _estack-4

_bstack = (ORIGIN (RAM) + LENGTH (RAM) - _Min_Stack_Size)

_estack = (ORIGIN (RAM) + LENGTH (RAM))

 

In the Keil builds the initial stack is set to __initial_sp, and descends too Stack_Mem
