CCS/TMS320C6678: no symbol are defined for ...

Hi,

I've notified the software experts. Their feedback will be posted here.

Best Regards,

thanks very much!

The problem seems to be caused by an interruption that is prone to the problem when the program returns from the interrupt routine.
The interrupt registration uses the following methods:

;create interrupt vector table for C6000 DSP
;--------------------------------------------------------------
;This file can be modified to add Interrupt Service Routine(ISR)
;for an interrupt, the steps are:
;1,reference to the externally defined ISR, for example
; .ref EDMA_ISR
;2,modify the corresponding entry in the interrupt vector table.
; For example, if interrupt 8 is used for EDMA, then you should
; modify the entry number 8 like below:
; VEC_ENTRY EDMA_ISR ;interrupt 8

I changed the way to interrupt the registration, using the CSL library function as follow,and the programme runs stable

registerInterrupt(48 , CSL_INTC_VECTID_4 , &GE_Message_ISR);
registerInterrupt(20 , CSL_INTC_VECTID_5 , &SRIO_ISR);

int32_t registerInterrupt(uint32_t event , uint32_t vector , CSL_IntcEventHandler isr)
{
hintc[vector] = CSL_intcOpen (&intcObj[vector], event, (CSL_IntcParam*)&vector , NULL);
if (hintc[vector] == NULL)
{
printf("Error: GEM-INTC Open failed\n");
return -1;
}

/* Register an call-back handler which is invoked when the event occurs. */
EventRecord.handler = isr;
EventRecord.arg = 0;
if (CSL_intcPlugEventHandler(hintc[vector],&EventRecord) != CSL_SOK)
{
printf("Error: GEM-INTC Plug event handler failed\n");
return -1;
}

/* clear the events. */
if (CSL_intcHwControl(hintc[vector],CSL_INTC_CMD_EVTCLEAR, NULL) != CSL_SOK)
{
printf("Error: GEM-INTC CSL_INTC_CMD_EVTCLEAR command failed\n");
return -1;
}

/* Enabling the events. */
if (CSL_intcHwControl(hintc[vector],CSL_INTC_CMD_EVTENABLE, NULL) != CSL_SOK)
{
printf("Error: GEM-INTC CSL_INTC_CMD_EVTENABLE command failed\n");
return -1;
}

return 0;

}

I do not know very well about the function CSL_intcOpen /CSL_intcPlugEventHandler/CSL_intcHwControl ,would you give me some reference?

Thanks again for your reply!

All of these CSL functions that you are looking for are provided here:
pdk_c667x_x_x_x\packages\ti\csl\src\intc

You can look at the details of the implementation there.
