Compiler: The stack pointer(SP) points to an invalid address

Pan Hui

Tool/software: TI C/C++ Compiler

Hi,

An exception occurs during the CPU run and goes into the faultISR function,and the stack pointer points to an invalid stack address.

In the CMD file we set the stack address range: 0x1FFFC000 to 0x1FFFC1FF. However, the current stack pointer points to 0x1FFFBFE0(Invalid address)

Environmental information:

CPU：28388D(core CM)；Compiler：CCS9.1

Debugging information：

Figure1：Core register information

Figure2-3：CM core status register information

Hi Pan,

Did you try increasing stack size and does that fix this issue ?

Yes, Increasing the stack size can solve the current problem, but we need to know where the stack overflow occurs. And is there a good debugging method to find the cause?What should we consider to set the reasonable stack size?

Looking forward to your reply.

Thank you!

Hi Pan,

Sorry for late reply. Since it was about ARM debug, I hope you were able to find some online material for this and resolve the issue. Let us know if you have any further device specific query.
