Stack problem when calling function

kimchan_eb — Mon, 26 Feb 2018 08:04:40 GMT

Hello,

Here are two pictures that show the change of stack after step into sub function.

Because of the stack change, it won't return normally back to the place where it called it, instead, it will "return" to 0xFFFF which is incorrect.

I also test other test cases and didn't find any similar problem.

So how can I fix the problem?

Codewarrior version is

Target ECU is S12G192.

I think I found the solution.

It's because stack size is not enough.

After I change stack size 0x100 to 0x200 in prm file. There will be no more this question.
