Tool/software: TI C/C++ Compiler

Team,
I got an inquiry about sample program of SimpleLink CC13x2_26x2 SDK from my customer. Customer is suffering from the HardFault exception in sample project - . Simple Broadcast. I have tried to build the simple broadcast sample and tried to do debug. It appears the program exit reached with HardFault exception as below:

///////////////////////////////
Mon Jan 20, 2020 13:21:46: Program exit reached.
Mon Jan 20, 2020 13:21:46: EXIT 0
Mon Jan 20, 2020 13:21:46: HardFault exception.
Mon Jan 20, 2020 13:21:46: The processor has escalated a configurable-priority exception to HardFault.
Mon Jan 20, 2020 13:21:46:   A precise data access error has occurred (CFSR.PRECISERR, BFAR) at data address 0x20014048.
Mon Jan 20, 2020 13:21:46:
Mon Jan 20, 2020 13:21:46: Exception occured at PC = 0xffffffff, LR = 0x0
Mon Jan 20, 2020 13:21:46:
Mon Jan 20, 2020 13:21:46: See the call stack for more information.
Mon Jan 20, 2020 13:21:46: The stack pointer for stack 'CSTACK' (currently 0x20003430) is outside the stack range (0x20013C00 to 0x20014000)
///////////////////////////////

This phenomenon would be appeared in case of using the IAR-EW. The CCS does not have any problem. It also happen on both SDK3.30 and SDK3.40.

Could I have your comment on this?

Regards,
Nonaka

    Hi,

    Have you verify if the stack size you defined in CCS and in IAR are the same? From the last line of the log, I understand you have allocated 1024 bytes to the stack. Is it what you wanted? In addition, I understand that the error is raised due to an access to the address 0x20014048 (i.e. 0x48 [meaning 72] out of the stack). Does this ring any bell?

    In summary:

    • verify the stack size on the IAR project (and compare it to the one defined for the CCS )

    I hope this will help,

    Kind regards,

    Hi,

    Yes, I have confirmed the stack size defined in linker configuration lile - cc26xx_app_and_stack_agama.icf. It is the same value as CCS's one.
    Please note thatI have not made any changes to the sample project(source code, configuration files and so on).

    ////////////////////////////////////////////////////////////////////////////////
    // Stack

    define symbol STACK_SIZE = 0x400;
    define symbol STACK_START = RAM_END + 1;
    define symbol STACK_END = STACK_START - STACK_SIZE;
    //
    define symbol STACK_TOP = RAM_END + 1;
    export symbol STACK_TOP;

    Hi Nonaka,

    Thank you for your patience. I was out for a couple of days.

    Can you verify the following for me:

    - Is IAR using the expected files? I have seen cases where IAR was not taking in consideration the right .c and .h files due to some error while setting the SDK version

    - Are the sysconfig files generated through IAR the same as the ones generated through CCS?

    - Can you try to compile using IAR installed on a different computer?

    - Can you precise which version of IAR you are using?

    Regards,
