@brief Support for the Nordic nRF51 Dongle
|
|
|
|
## Overview:
|
|
The nRF51822 is a multi-protocol SoC ideally suited for Bluetooth® low energy
|
|
and 2.4GHz ultra low-power wireless applications from Nordic Semiconductor. The
|
|
nRF51822 is built around a 32-bit ARM® Cortex™ M0 CPU with 256KiB flash + 16KiB
|
|
RAM. The embedded 2.4GHz transceiver supports Bluetooth low energy as well as
|
|
2.4GHz operation.
|
|
|
|
Nordic's development kit contains two different boards:
|
|
- **pca10000**: a USB-dongle containing the nRF51822 and a RGB-Led
|
|
- **pca10005**: two a basic nRF51822 boards making the MCU pins available
|
|
|
|
While the pca10000 contains an on-board J-Link debugger, the pca10005 boards
|
|
have to be flashed/debugged using the (included) external J-Link device.

## Flashing the Device:
|
|
The nRF51822 PC10000 board is shipped with an on-board JLink debugger.
|
|
However the PC10004/5 board uses an external flash tool as seen in the Image
|
|
above. Under Linux, the easiest way flashing the nRF51822 is using the JLink
|
|
tool(version >4.85) from [Segger](http://www.segger.com/jlink-software.html).
|
|
|
|
To interact with the board just start the tool using the following command:
|
|
`# JLinkExe -device nrf51822`
|
|
|
|
For RIOT itself there is a Flash-Script available. When using any of the
|
|
Examples type in the following command:
|
|
`# Make -B clean flash`
|
