Compiler generates FPU instructions for a device without an FPU - Updating code for a new SoC (nRF52832)

[ConnorOsborn]

Converting old code for a nRF51822 to the new SDK(15.3.0) for an nRF52832, this error happens:

#error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"
In the file <SDK>\components\toolchain\cmsis\include\core_cm0.h line 138

When checking where __FPU_PRESENT is defined, it is set to 1

You will probably want to include core_cm4.h rather than core_cm0.h for the nrf52832.

Thank you! Turns out I still had nrf51.h in a couple files in the project, which contained the core_cm0.h include.  Including nrf52.h instead fix the issue.

Hi!
I am a beginner here. 
Please, could you share how did you do it? 

Thanks!

Hi Mylena, 

Please create a new support case. Thanks.

I wrote a python script to search for #include nrf51.h and replaced them with nrf52.h.
