TMS320F28377S: _system_post_cinit() 0x3FE493 (an error occurred: failed to parse the previous frame FP)

Hi,

I have the following issue:
I want to start debugging the following code section shown in the image below. Compiling and Linking are all successful. The FreeRTOS was configured with the sysconfig tool and implemented in the empty_driverlib_project.

As soon as the FreeRTOS_init(); function was called, the debugger ran into the following error “_system_post_cinit() 0x3FE493 (an error occurred: failed to parse the previous frame FP)” see in the image below.

When the FreeRTOS_init(); function is not implemented (commented out), this error doesn’t occur, and the debugger runs normally. Does the usage of the RTOS disturb the debugging process?

Are you familiar with that problem?

With kind regards

Can you share the generated FreeRTOS_init code? Could you also try out the FreeRTOS example provided in C2000ware\kernel\FreeRTOS\demo?

Veena

void FreeRTOS_init(){
    myTask0_init();
    myTask1_init();
    //
    // Start the scheduler
    //
    vTaskStartScheduler();
}

Unfortunately, I have not found any examples in the folder designed for the F2837xs family.

Have you allocated the stacks and heap memories to an address in the range 0-0xFFFF? This is required since C28 Stack pointer is 16 bit long and does not have access to addresses above 0xFFFF

I was able to fix the error. I modified the main code shown in the following code sequence:

void main(void)
{
    //
    // init
    //
    Device_init();
    Interrupt_initModule();
    Device_initGPIO();
    Interrupt_initVectorTable();
    Board_init();
    FreeRTOS_init();

    //
    // Loop forever. This statement should never be reached.
    //
    while(1)
    {
    }

This fixed all the errors.
