Steps:

   from: https://launchpad.net/gcc-arm-embedded

2. create your project file

note[1]: OpenOCD supported (0.9-trunk advised) if you set FLASHER as OpenOCD at Makefile.common file. You also need to adjust $OPENOCD command for your OpenOCD compatible dongle at same file. You can also flash "softdevice 6.0" with OpenOCD flasher. PS: This patch increases OpenOCD speed by 10 ( http://openocd.zylin.com/#/c/2204/ )

note[2]: Currently JLink (for MacOSX) v4.90b will not require disabling CDC, highly recommend use that new version, that will allow use GDB and virtual com port simutaneously.

note[3]: Linux and OpenOCD support was submitted by https://github.com/EUA, if you have any problems please @him or create a issue on his https://github.com/EUA/nrf51822-posix-build-scripts
