nrf51822-linux-template

This project aims to be a template for building applications in a Linux environment using the nRF51822 chip from Nordic Semiconductors.

Dependencies

GNU Tools for ARM Embedded Processors

You can download it from here. If you are using a system with apt-get, there is a PPA here.

J-Link v474

You can download the linux version from here. You'll need to provide a original serial key to access the files.

This project was tested using version 474. It may not work against other versions.

nRF51822 SDK v4.3.0.27417

You can download it from here. You'll need to provide a original serial key to access the files.

The file is a Windows executable file. But you can use wine to install it.

This project was tested using version 4.3.0.27417. It may not work against other versions.

Configuration

The Makefile contains the general build process and should be generic. You need to edit Makefile.project to add project specific configuration. The current Makefile.project contains configuration to build an example blink application (implemented by src/main.c).

These are the variables you can put inside Makefile.project:

NRF51_SDK_PATH

Full path to Nordic nRF51 SDK. This variable should contains to the root of the SDK.

JLINK_PATH

Full path to JLINK software.

SOC

Specify the current SoC. Possible values are defined in nrf.h.

####SOC_VARIANT

Specify the variant of the SoC. Possible values are xxaa (256 kb) and xxab (128 kb).

BOARD

Specify the board. Possible values are defined in boards.h.

USE_SOFTDEVICE

Specify if the Soft Device is going to be used or not. Possible values are s110 and blank.

NRF51_SOFTDEVICE

Path to the hex file containing the softdevice.

PROJECT_TARGET

Specify the name of the build target.

Other variables

• PROJECT_CFLAGS
• PROJECT_LDFLAGS
• PROJECT_INCLUDE_PATHS
• PROJECT_C_SOURCE_PATHS
• PROJECT_C_SOURCE_FILES
• PROJECT_ASM_SOURCE_PATHS
• PROJECT_ASM_SOURCE_FILES

Build

The Makefile contains the following rules:

• make will build the firmware and put it inside build directory. *make clean will erase the build directory.
• make erase will erase the firmware inside nRF51.
• make install or make upload will flash the firmware inside nRF51.
• make softdevice will flash the softdevice inside nRF51 (it will first erase the flash).
