No call stack when stoping in library function

Other Parts Discussed in Thread: TMS570LS3137

Hello,
I'm using CCS 5.5.0.00077 with TI v5.1.4 compiler on a custom board with TMS570LS3137.
My program stops because of a MPU access error in the no_stm_memcpy function from the RTS library. As you can see in the attached screenshot there is no call stack.
Do I have to enable this Feature somewhere?
Thanks in advance.
Regards,
Christian

    Christian,

    Do you have a snippet of code that could potentially show this issue? I vaguely recall this was an issue with our debugger several years ago, but I can't seem to find it anymore (the only non-issue I found is at this post, but I checked the RTS sources and found this is not a problem).

    Cheers,

    Rafael

    Rafael,
    I have a project attached where you can see that issue.
    In the task I copy one array to another array but MPU protects the destination array and generates a data abort in memcpy function.
    I've tested it with TMS570LS31x Hercules USB Stick Development Kit (TMDX570LS31USB)
    Thanks in advance.
