This board has an ARM Cortex-M3 MCU and is used to program and debug an application running on the BLE Nano via SWD. DAPLink is an open source project by ARM mbed team.

For V1.0 version of the DAPLink USB dongle, you can update it to the latest interface firmware called DAPLink which is supported and developed by ARM mbed.


Updating Interface Firmware


In case you have changed the USB interface firmware inside the DAPLink chip and want to restore to the default one or upgrade to the lastest version, follow the steps below:


1. Press and hold the reset button on your USB dongle board


2. Connect it to an USB port of your PC


3. Release the button and the LED will keep flashing (slowly)


4.1 For Windows:


Simply drag the firmware (.bin) to the MSD drive (e.g. E:), labelled 'MAINTENANCE' (for F103 DAPLink)


4.2 For Linux or Mac OSX (10.9.x), use the follow command from the Terminal:


Usage: dd if=src_firmware.bin of=/Volumes/MAINTENANCE/dst_firmware.bin conv=notrunc


Example: dd if=DAPLink_F103_BLENano.bin of=/Volumes/MAINTENANCE/DAPLink_F103_BLENano.bin conv=notrunc

4.3 For Mac OSX (10.10.x / 10.11.x):

sudo mount -u -w -o sync /Volumes/MAINTENANCE; cp -X ~/Desktop/DAPLink_F103_BLENano.bin /Volumes/MAINTENANCE/

Wait for 10 seconds and remove the board from the USB port

Reconnect it to the USB port, your OS will show a drive labelled 'DAPLink' (for DAPLink firmware) or 'MBED' (for CMSIS-DAP firmware)
