TMS320F28388D: Creating SYSBIOS HWI at runtime

Do you mind sharing a snippet of the code where you're creating the Hwi? Can you use breakpoints or single step through the code to confirm what line in the Hwi code leads to the error being raised?

Do note that we are no longer recommending SYS/BIOS for new projects, so if this is a new project, we recommend looking into using our FreeRTOS implementation instead. There's a little more information in this post.

The code is almost a copy from doc. I'm trying to create a hwi for timer 1:

        Hwi_Params hwiParams;
        Error_Block eb;

        Hwi_Params_init(&hwiParams);
        Error_init(&eb);

        // set the argument you want passed to your ISR function
        hwiParams.arg = 0;

        // set the event id of the peripheral assigned to this interrupt
        hwiParams.eventId = 10;

        // don't allow this interrupt to nest itself
        hwiParams.maskSetting = Hwi_MaskingOption_SELF;
        Hwi_create(13, incrementMilliseconds,  &hwiParams, &eb);

Following last 'call Hwi_create' leads to Hwi.h:

#define Hwi_create ti_sysbios_hal_Hwi_create

and to app_pe28FP64.c:

/* create */
ti_sysbios_hal_Hwi_Handle ti_sysbios_hal_Hwi_create( xdc_Int intNum, ti_sysbios_hal_Hwi_FuncPtr hwiFxn, const ti_sysbios_hal_Hwi_Params *paramsPtr, xdc_runtime_Error_Block *eb)
{
    xdc_runtime_Error_raiseX(NULL, ti_sysbios_hal_Hwi_Module__id__C, NULL, 0, xdc_runtime_Error_E_generic, (xdc_IArg)"create policy error", 0);
    return NULL;
}

A related question: is it allowed to mix sysbios HWIs and plain interrupts?

Thanks, that resolved my issue.

Do you also know the answer to this question?
