AdaLink (https://adafru.it/fPq) (Python)

This command line tool is a python-based wrapper for programming ARM MCUs using either a Segger J-

Link (https://adafru.it/fYU) or an STLink/V2 (https://adafru.it/ijF). You can use it to reflash your Bluefruit LE module using

the latest firmware from the Bluefruit LE firmware repo (https://adafru.it/edX).

Details on how to use the tool are available in the readme.md file on the main

Adafruit_Adalink (https://adafru.it/fPq) repo on Github.

Completely reprogramming a Bluefruit LE module with AdaLink would require four files, and would look something like

this (using a JLink):

You can also use the AdaLink tool to get some basic information about your module, such as which SoftDevice is

currently programmed or the IC revision (16KB SRAM or 32KB SRAM) via the --info command:

Adafruit nRF51822 Flasher (https://adafru.it/fVL) (Python)

Adafruit's nRF51822 Flasher is an internal Python tool we use in production to flash boards as they go through the test

procedures and off the assembly line, or just testing against different firmware releases when debugging.

It relies on AdaLink or OpenOCD beneath the surface (see above), but you can use this command line tool to flash your

nRF51822 with a specific SoftDevice, Bootloader and Bluefruit firmware combination.

It currently supports using either a Segger J-Link or STLink/V2 via AdaLink, or GPIO on a Raspberry

Pi (https://adafru.it/fVL) if you don't have access to a traditional ARM SWD debugger. (A pre-built version of OpenOCD

for the RPi is included in the repo since building it from scratch takes a long time on the original RPi.)

We don't provide active support for this tool since it's purely an internal project, but made it public just in case it might

help an adventurous customer debrick a board on their own.
