Even after including the header file for the syncdelay,i,e "fx2sdly.h" iam getting an error c202 unknown identifier . iam developing a firm ware for fx2. also i need binary file to download the firm ware . is there a way to generate binay file from keil. i have a board with cypress fx2 and spartan. can any help
What have you set _IFREQ and _CFREQ to? What does _SCYCL evaluate to?

hai mike , thanks . iam having a diiferent file for the syncdelay macro where the codings are different from what u have given. and it is given as writedelay ( )instead of syncdelay. Thanks i found where iam wrong . thanks punitha
