MSP430FR2355: IQmathLib Hardware MPY32 doesn't work

zero_cool

Part Number: MSP430FR2355

Hi,

I have issue with iQmathLib and hardware MPY32 at MSP430FR2355, If I link to my project ..\IQMATHLIB_01_10_00_05\libraries\CCS\MPY32\4xx IQmathLib.a and QmathLib.a _QNmpy function return value 0, QNmpy function only work with ..\IQMATHLIB_01_10_00_05\libraries\CCS\MPYsoftware software MPY IQmathLib.a and QmathLib.a.

Do I need to something else except drag I drop IQmathLib.a and QmathLib.a and link it to project.

I'm using calculation from example code from ..\IQMATHLIB_01_10_00_05\examples\msp430
