nRF51 does not have FPU so your compiler is generating soft FPU instructions. What are the project settings you have for Target->MicroLIB, target->use Float Hardware?

Hi,

Thanks for your answer.

Device: 51822 IDE: Keil-472 SDK Version: 10-alpha I used soft-device.

And the debugger and complier is what the SDK-10-Demo used by default, for I don't so familiar about how to change config I don't try to any change at all.

Hi,

You'd better show your development environments to get answers. Device name, compiler, debugger, SDK version, whether to use the SoftDevice or not, and so on.

I guess may the debugger has something wrong when call the float point liburay, but how can I config the Keil-472 correctly? I used the official Demo code to develop my project, without any config changed.
