Locating Stack Pointer, Stack Start Address and End Address - RA2L1

Hello,

Thanks for reaching out to Renesas Engineering Community.

The stack pointer is stored in 'SP' register. You can see its value from the 'Registers' tab under the General Registers.

To find the start and end address of the stack open the .map file in the Debug folder of your project and search for  .stack.

In the below project the size of the stack is 0x500 as specified on the BSP tab and the memory range is 0x20000148 - 0x20000648.

Why do you want to customize the stack address ?

Best regards

Hi AZ_Renesas,

Thank you for your reply.

Below Screen shot,

My map file is different from yours. .bss start immediately after the .stack. the difference between 2 is 0x400 i.e 1Kb.

How can I define this .stack  in linker to to map in other location and differnt size in SRAM.

Thanks

You can do this by modifying the linker script (fsp.ld file under script folder).

For example to change the stack start address to 0x20000278:
