Nordic, nRF52 Preview DK

The nRF52 Preview DK is Nordic's development kit for the nRF52832. These notes cover the SDK, JLink, the GCC toolchain, and programming the board.

Prepare

Install SDK

Get latest SDK from https://developer.nordicsemi.com/nRF52_SDK/nRF52_SDK_v0.x.x/ (ex. nRF52_SDK_0.9.2_dbc28c9.zip)
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)
Edit ./components/toolchain/gcc/Makefile.posix to fit your toolchain setting if necessary

Install JLink

Download "Software and Document pack" from https://www.segger.com/jlink-software.html according your platform (ex. x86_64)
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
