HWI on omap3530

Hi All

   I am working on omap 3530 . I am trying to generate an IDMA interrupt ( IDMA event mapped to event 14 on omap , correct me if i am wrong ) I am using bios project . I am Not using the ECM as i want just to bring out 1 interrupt . in the HWI4 bios i have given the C function and used dispatcher . Interrupt selection number as 14 .

I hope these setting should be sufficient . I am enabling IDMA with interrupt enable  and able to transfer the data but no interrupt is generated . and it is given that no need to enable any interrupts by usinf HWI_enable api  as bios enables once main is entered . i tried enabling , but same result .

Am i missing something ?

Thanks

Suresh
