Enbaling hardware linkage on IAR workbench

Yaron

Hi

I am working with Nordic nRF52832, which contains Cortex™-M4F CPU with FPU unit.

In order to get the best performace I want to enbale hardware linkage.

How do I do it? How can I make sure that hardware linkage is working?

Thanks

Yaron

    Hi yaronapel, welcome to the Community!

    I have moved your questions to Software Development Tools where I think it is a better fit.

    Hello yaronapel,

    You can choose the FPU from the Target options of the General Options.

    1 Choose Project>Options to display the Options dialog box.

    2 Select General Options in the Category list.

    The Target options specify target-specific features for the IAR C/C++ Compiler and Assembler.

    The below shows the Target Option Dialog image. I'm sorry for the Japanese version.

    My EWARM version does not support Nordic nRF52 (only support nRF51).

    Therefore I cannot specify the processor as nRF52 by 'Device' but I can specify it as Cortex-M4 by 'Core'.

    And then, we can specify FPU to VFPv4 or nothing.

    I hope this will help you.

    Best regards,

    Yasuhiko Koumoto.
