    Hi steve zhang,

    Are you using the PSP drivers and EDMA drivers?  If so, what versions?

    Also, what version of BIOS are you using?

    I'm not familiar with the EDMA code, but I can try to help you.

    HWI_dispatchPlug() is a BIOS API that's used to map a function to an interrupt at run time.

    The above code looks to be mapping the EDMA function EDMA_intDispatcher to some interrupt number.  This will cause the EDMA_intDispatcher function to run as the ISR for that interrupt.

    I took a quick look at the doxygen API docs that ship with EDMA version edma3_lld_02_11_05_02.  I didn't see this function.  Do you know where this function comes from?
