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?

Hi Sigured,

Thanks for your reply. I am looking onto the link that you have suggested. Its really helpful. I have resolve this issue. But can anyone implemented any basic transforms in NRF52 and IAR. Do you have link for this sample example.

Also there are no sample projects on DSP library?
