check stack & heap size during debug in S32DS

skseofh — Fri, 23 Oct 2020 00:32:21 GMT

I'm using S32144 and S32DS.

During Debugging, is there any way to check stack & heap size?

If there is, please let me know!

Thanks

Hi,

In addition, I like this simple high water mark method: fill whole stack by some pattern like 0xAA (for example by debugger) and then run the code. Examine as many program paths as possible and then check the stack – you will see which part of the stack has been rewritten and you can adjust the size accordingly.
