PRU-ICSS-INDUSTRIAL-SW: How to realize EtherCAT Status LEDs using PRU-ICSS-Industrial-SW?

Hi Vineet,

I think I found the cause of my problem, but I still need some assistance to get it working. (I am using SDK 7.1 and I followed the migration guide. My EtherCAT Application is also working in TwinCAT - with the exception of the status LEDs).

There is a function called ECAT_SetLedIndication() (in ecatappl.c), which gets called in MainLoop() (also in ecatappl.c), which should do the job of blinking the EtherCAT Run/Err LEDs.

However, my application throws errors, when I try to use the default main() function:

void main(void)
{
    /* initialize the Hardware and the EtherCAT Slave Controller */
#if FC1100_HW
    if(HW_Init())
    {
        HW_Release();
        return;
    }
#else
    HW_Init();
#endif
    MainInit();

    bRunApplication = TRUE;
    do
    {
        MainLoop();
        
    } while (bRunApplication == TRUE);

    HW_Release();
#if _PIC24
    return 0;
#endif
}

As a workaround, I used the main function from tiescappl.c:

int main()
{
    common_main();
    return 0;
}

With this function, my EtherCAT Application is working. But the status LEDs do not, since there is no call of MainInit().

Why do I get errors when trying to use the default main function? I build the application using the provided projectCreate.bat tool. So the CCS project should be fine.

Thanks again for your help.

Hi Felix,

Sorry, re-opening this thread after some time.

Is this issue still open ?
