Configuration of Stacksize and Heapsize when using CubeMX

Posted on November 22, 2015 at 17:01

In my Stm32F401 based project, I use CubeMX 4.11.0 for generation of initialization code. My IDE & toolchain is SW4STM32.

Within the generated code, there is also the linkerscript STM32F401VCTx_FLASH.ld, which contains:

/* Generate a link error if heap and stack don't fit into RAM */

_Min_Heap_Size = 0x200; /* required amount of heap */

_Min_Stack_Size = 0x400; /* required amount of stack */

Since I'm running FreeRtos with heap_4, I dont need this kind of heap.

And on the other side, I need the min stack size increased to 2k.

For the first, I'd adjusted the values inside of the linkerscript manually, like this:

_Min_Heap_Size = 0;      /* required amount of heap  */

_Min_Stack_Size = 0x800; /* required amount of stack */

and this works as expected.

But unfortunately, each time when I do code regeneration with CubeMX, my changes were lost.

This brings up the question, were to configure these both parameters in CubeMX?

As far as I see, this is a missing feature, isn't it?
