CC1310: Modifying startup_iar.c file

Part Number: CC1310

Hi Team,

My customer has a project based on TI-RTOS easylink, he want to know what will happen when code running away.

Is there any way to modify startup_iar.c file or exception handling functions like FaultISRHandler、ResetISR、NmiSRHandler、IntDefaultHandler? 

Best Regards

Viki

    I'd like to know how TI provide TI RTOS demo for abnormal processing. How can I add hint in abnormal interrupt service(FaultISRHandler), and then reset cc1310.

    Hi,

    This should not be a problem. You can modify the fault handlers in the startup code with assert and make the code more production friendly.

    Thanks.

    Hi，

    In TI  RTOS rfWsnNode  project does not contain "startup_iar.c".Seems to be encapsulated into the library file.

    When I add "startup_iar.c" in rfWsnNode project , and try to modify the exception handler(such as FaultISRHandler(void)). The compiled found that conflict.

    Error[Li006]: duplicate definitions for "ResetISR"; in "E:\work\02_Product\Source\CC1310_bosma\Debug\Obj\startup_iar.o", and "C:\ti\simplelink_cc13x0_sdk_3_10_00_11\kernel\tirtos\builds\CC1310_LAUNCHXL\release\iar\package\cfg\release_prm3.orm3"

    Error[Li006]: duplicate definitions for "__vector_table"; in "E:\work\02_Product\Source\CC1310_bosma\Debug\Obj\startup_iar.o", and "C:\ti\simplelink_cc13x0_sdk_3_10_00_11\kernel\tirtos\builds\CC1310_LAUNCHXL\release\iar\package\cfg\release_prm3.orm3"

    How do I do to modify the function in TI  RTOS rfWsnNode project.

    Hi Viki,

    You can easily plug your own fault handler as such:

    #include <ti/devices/DeviceFamily.h>
#include DeviceFamily_constructPath(driverlib/interrupt.h)
#include DeviceFamily_constructPath(inc/hw_ints.h)

void customHardFaultIsr(void)
{
   /* This code runs whenever a hard fault is raised */
}

int main(void)
{
  IntRegister(INT_HARD_FAULT, customHardFaultIsr);

  /* ... rest of code ... */
}

    No need to include startup_iar or whatnot.
