CCS/CC1352R: Difference restart to restart via debugger

Erwin Ahlers

Part Number: CC1352R
Other Parts Discussed in Thread: SYSBIOS

Tool/software: Code Composer Studio

Hi,

I use Code Composer Studio together with XDS110 Debugger to put my program into the CC1352R device. When I start debugging, means the program is loaded directly via debugger, it works. But when I press the Restart button (menu Run / Restart) the processor does a reset but it doesn't work. I'm running into the exception handler where the CPU_SCS_CFSR_INVSTATE bit is set.

So is there something in the processor that is not initialized to default values when I press the restart button? There has to be a different between both kinds of program start. I also don't know that CPU_SCS_CFSR_INVSTATE really tells me. I'm new with CC1352R processors, before we used ATMEL processors.

I'm also using TI-RTOS if that helps. At compile time first sysbios/rom_sysbios.aem4f is build which seems to be some special firmware first loaded (into special areas of processors flash?). Could this be the difference?

Thanks in advance

Erwin

    What SDK version and example do you test this?

    When I go under Project Properties / General / Products it showd my SimpleLink CC13x2 26x2 SDK under which I've selected 3.40.0.02

    So I guess this is the SDK I'm using.

    My software is not an example Software. It's out product software.

    Regards

    Erwin,

    In CCS clicking the "restart" button just moves the PC to the entry point. From CCS documentation:

    • Reset: performs a reset on the core or device. The small inverted arrow allows selecting among the available resets.
    • Restart: issues a restart when either symbols or a program is loaded to the target device. A Restart simply re-positions the PC register to the entry point (typically _c_int00 or the reset vector).

    It's possible that something isn't getting set back to its initial/default state which could be causing issues. You probably want to use the reset button to reset the MCU to default state.

    Regards,
