Hi.

[quote user="Weidetracker"]it didn't make a difference[/quote]

If you are using Segger Embedded Studio, you must re-load the project for changes in prj.conf to take effect.

If you only want to change the current build, you can select Project -> Configure nRF Connect SDK Project to open a configuration tool.

If you build from the command line, you can use ninja menuconfig (inside the build folder) to achieve the same.

Best regards,

Didrik

Where do I find the menuconfig? Is it my prj.conf file?

I added

CONFIG_NEWLIB_LIBC=y

to my prj.conf, but it didn't make a difference.

Thanks for your help!

Zephyr config has an option to enable "newlib" libc in the menuconfig. This should also enable math.h libs IIRC.
