Prepare

Install SDK

1. Get latest SDK from https://developer.nordicsemi.com/nRF52_SDK/nRF52_SDK_v0.x.x/ (ex. nRF52_SDK_0.9.2_dbc28c9.zip)
2. Get SDK with FreeRTOS example from http://developer.nordicsemi.com/nRF5_SDK/nRF5_SDK_v11.x.x/ (nRF5_SDK_11.0.0-2.alpha_bc3f6a0.zip)
3. Edit ./components/toolchain/gcc/Makefile.posix to fit your toolchain setting if necessary

Install JLink

1. Download "Software and Document pack" from https://www.segger.com/jlink-software.html according your platform (ex. x86_64)
2. decompress and make a symbolic to /opt/SEGGER/JLink
   1. ln -s ~/Downloads/JLink_Linux_V510c_x86_64 /opt/SEGGER/JLink

Toolchain

sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded sudo apt-get update sudo apt-get install gcc-arm-none-eabi

Programming

1. Softdevice
    ex.
    sudo /home/tommy/projects/mbed/nRF52/NrfJProg_7_7_0_Linux/nrfjprog --family NRF52 --program ~/projects/mbed/nRF52/s132_nrf52_1.0.0-3.alpha/s132_nrf52_1.0.0-3.alpha_softdevice.hex

2. change dir to example 
    ex.
    sudo ~/projects/mbed/nRF52/NrfJProg_7_7_0_Linux/nrfjprog --sectorerase --family nRF52 --program _build/nrf52832_xxaa_s132.hex

3. sudo ~/projects/mbed/nRF52/NrfJProg_7_7_0_Linux/nrfjprog --sectorerase --family nRF52 --program _build/nrf52832_xxaa.hex
4. power recycle to take effect
