CCS/MSP432P401R: __delay_cycles unresolved symbol

Hi Bob,

Where is the error coming from? The compiler? Or is it coming from the IDE? 

Please provide all the build output from the build console. You can copy and paste to a text file and attach the text file to this thread.

Thanks

Hi,

More information, when I built a project from "new" rather than import an old, and then copied in the very same files, the problem did not appear.

Here's the error build below:

I think _delay_cycles() only has 1 underscore at the beginning.

Sorry, Keith, but this is a rare occasion where you are incorrect.  This intrinsic begins with two underscores.  Please search for it in the TI ARM compiler manual.

Thanks and regards,

That's what I get for getting the answer from other questions on the forum as opposed to my source code!
