Build infrastructure for using the nrf51 SDK
Download the Nrf51 SDK 8.0 from http://developer.nordicsemi.com/nRF51_SDK/nRF51_SDK_v8.x.x/ and unzip it into nordic.
Download the Segger RTT library https://www.segger.com/jlink-real-time-terminal.html and unzip it into segger.
- My build fails with
ld: cannot find -lc_s
The Nrf SDK uses libc_s which was replaced by libc_nano in GCC 4.9.
Go to your lib folder (e.g. gcc-arm-none-eabi-4_9-2014q4/arm-none-eabi/lib) and create a link to libc_s.a:
ln -s libc_nano.a libc_s.a
Do this for the subfolders as well (armv6 for nrf51, armv7 for freescale ...).
