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
* after you build successfully, use hex2bin. * give more details.
Iam new to keil c . i have included a macro syncdelay for my firmware design for fx2 usb. when I build. iam getting an error . unknown identifier syncdelay. i have included the header file for the Macro. thanks . ihave downloaded the utility hex2bin thanks punitha
copy paste your error message as well as the relevant code snippet. we are not mind readers, maaaaaaan!!! :-)

hai ,
this is my error
: error C202: 'SYNCDELAY': undefined identifier : error C202: 'SYNCDELAY': undefined identifier
i have included the header files as given below
#include "fx2.h" #include "fx2regs.h" #include "fx2sdly.h" // SYNCDELAY macro, see Section 15.14 of FX2 Tech. // Ref. Manual for usage details. syncdelay is a macro and i have includes the header file "fx2sdly.h". still the error is not gone .? what is wrong ?the coding is for GPIF design for the cypress usb
punitha
has it ever occurred to you that it might be important to post the macro itself and where and how it is used? you continuously refuse to post anything meaningful.
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
