If you want to use STACKTOP, we need define a segment for stack and pace predefined segment SSTACK into it. see below steps of using STACKTOP

Hope this helps.

Have a great day,

Hi Zhang,

Acctually, it's not what i'm looking for. In your case, you predefine a space for STKRAM (from x300 to x48F), however when I use processor expert to generate a similar configuration, it doesn't define any size for STACK. It just let the stack to be placed in all remanescent space of RAM segment.

In the project that i've attached, I don't use processor expert (because of very density code, almost fill uC ROM), but testing it like I said works fine.

I just doesn't understend what is the difference.

If you can test it, try to set processor build options like that:

Thank you.
