RTC's interrupt (interrupt no:63) can not wok

I use OMAPL137 with CCS3.3, version of dsp/bios is 5.41. I would like to trigger at one second by RTC's period interrupt

I set up RTC's register correctly. I tried to map interrupt number of 63 to HW14 directly , it works.

In my program , use EMDA(use 28 GPIO Bank 4 Interrupt , auto event trigger), in DSP/BIOS graphics edit, enabled "event combiner manager",

Under "event combiner manager" , i set event63, function : myRTC, check "unmask event source". Run my program,

EDMA transfer and myRtc don't work.   Is RTC interupt confilct with EDMA transfer? Wish someone can give me advise.

    fgh,

     

        You might want to set a breakpoint to see whether or not the event is getting capture in the EDMA3 Channel Controller, and whether or not the Transfer Controller successfully completes the transfer.

    Hi:

           I debug my program under dsp side, EDMA transfer and RTC interrupt can work  .

    But with  dsplink 1.6.3, GPP  load DSP program , EDMA transfer and RTC interrupt can not work   ,

    I think , maybe EDMA  is conflict with RTC interrupt .  How to correct it?
