how to set stack size of stm32

Abstract

stm32 project default stack size is: 0x1000 Byte, is 4KB if we want to use more biger stack. we need to adjust the stack size, but we only know the RAM size, if we set the RAM size of stack, the MCU doesn’t work.

how to set stack

the max stack size is: Rotal_RAM = RAM1 + RAM2(is ram2 is none you can assign the whole RAM to RAM1(stack))

set the stack accroding to the RAM1

MAX demo with RAM2

name	size
Total_RAM	0x10000(64k)
RAM1	0xc000
RAM2	0x4000

MAX demo without RAM2

name	size
Total_RAM	0x10000(64k)
RAM1	0x10000
