get warnings / errors

#225-D function "__NOP" declared implicitly core_cm4.h /BOOSTXL-EDUMKII_MicrophoneFFT_MSP432P401R/CMSIS/Include line 1789 C/C++ Problem

*** In my experience a warning like this indicates that the preprocessor #define __NOP was not included
*** Since __NOP is #defined as a macro in cmsis_armcc_V6.h I was assuming that the warning meant that the macro __NOP was not defined when it was reached in cor_cm4.h.

Hi David,

Thanks for pointing this out. This "warning" was introduced with MSPWare_2_40_00_37. We will get it fix in our next release.

As a workaround please modify your project core_cm4.h file:

1789 //      __NOP();
1790       __nop();

And

1872 //      __NOP();
1873       __nop();

Best regards,

David
