Hello,
customer uses the MSP430G2230 and wants to use the Stack Usage function in CCS? Is there a description of this tool?

Holger,

Unfortunately there is no formal document that talks abut the Stack Usage tool, but its functionality should be pretty straightforward. Are there any specific questions?

A few resources talk about stack usage.

Section 5 of:
processors.wiki.ti.com/.../Stack_issues

Specific for MSP430:

Hope this helps,
Rafael

Hello Rafael,
thx for answering. Btw, I think I can use the MSP430 "break on stack overflow" only when debugging not in runtime. Right?

Holger,

Yes, you are correct.

The way I see it, an implementation of a dynamic mechanism to monitor stack usage would steal precious bytes of a G2230 and is not necessarily guaranteed to work, given that a corrupt stack may lead to absolutely unpredictable outcomes. That is why we try to have tools to statically analyze stack usage.

Rafael

Hello Rafael,
there is no tool to warn you if the stack size is too little, right? Like the Stack Usage tool, it show that you need eg 20bytes (static) but you don't get a warning/error if you only reserved 10bytes.
