Installation guide
This document describes in details how to turn a Nordic nRF52840 board into a working FIDO2 security key.
Pre-requisite
Hardware
You will need one the following supported boards:
- Nordic nRF52840-DK development kit. This board is more convenient for development and debug scenarios as the JTAG probe is already on the board.
- Nordic nRF52840 Dongle to have a more practical form factor.
In the case of the Nordic USB dongle, you will also need the following extra hardware:
- a Segger J-Link JTAG probe.
- a TC2050 Tag-Connect programming cable.
- a Tag-Connect TC2050 ARM2010 adaptor
- optionally a Tag-Connect TC2050 retainer clip to keep the spring loaded connector pressed to the PCB.
Although OpenOCD should be supported we encountered some issues while trying to flash a firmware with it. Therefore we suggest at the moment to use a Segger J-Link probe instead.
