"What is the reason for such error?. The help is not very clear to me" In what way unclear? Here is the description: L127: "The specified external symbol, requested in the specified module, has no corresponding PUBLIC symbol in any of the input files." http://www.keil.com/support/man/docs/l166/l166_l127.htm In your case, "The specified external symbol" is Convol; is there a Public definition of Convol anywhere in your Project?
