Fatal Error[Pe035]: #error directive: "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"

Hi All,

I am getting following error while compiling template example with DSP CMSIS library in IAR.

Fatal Error[Pe035]: #error directive: "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)" \nRF5_SDK_11.0.0_89a8197\components\toolchain\CMSIS\Include\core_cm4.h 165

Does anyone has any idea regarding this?

well the error message seems very clear doesn't it. Have you checked __FPU_PRESENT to see if it's set or not? If not, why not. A very quick check shows __FPU_PRESENT is set in nrf52.h, are you not including that, are you trying to build the code for nrf51?

Yes, we have a DSP example. It's located in the folder: <SDK_InstallFolder>\examples\peripheral\fpu_fft
