The compile and loding was success!
But the trigger from "FP gate enabled", DMA error messages occur.

file : drvSisfadc.c
function : readContiguous()
Error Message : Can't perform DMA: S_errno_EFAULT


STATIC void readContiguous(sisInfo *psisInfo,

    int nmax,int *nskipHigh, int *nskipLow)

Oops, I didn't realize I was using that routine here - add this function
somewhere, I have it in sysLib.c:
