A tool to flash and erase nRF devices

• J-Link programmer or J-Link OB microcontroller (on-board)
• Segger's JLink software (V4.80)

Currently, only the nRF51822 chip is supported.

To flash new firmware:

$ nrftool flash FIRMWARE ADDRESS [--verbose]

To erase current firmware:

$ nrftool erase [--verbose]

If JLinkExe can't be found in your PATH, it can be specified using --jlinkexe option:

$ nrftool --jlinkexe path/to/your/JLinkExe erase
