Is your micro:bit board in Maintenance mode by mistake? This page should help.

Maintenance mode

If you have a BBC micro:bit, or other Mbed hardware, and it is connecting as a drive called MAINTENANCE instead of MICROBIT, then you are in the maintenance mode provided for updating the DAPLink software (see below).

The way you access maintenance mode is by pluging in your board to your computer's USB port while holding down the reset button. If you are in maintenance mode by mistake, this might be how it happened

Press the button on the board


To leave maintenance mode, unplug the board from USB, make sure the Reset button is not pressed, and plug the board back in.


Plug in board


The board should now show up with the correct name (for example, MICROBIT). If this fails to work, please follow the steps outlined in “Updating your DAPLink firmware” below

What is DAPLink?

DAPlink is the software that runs on the interface chip of an Mbed enabled board. It provides the USB interface that allows you to drag-and-drop binaries onto the target microcontroller.

Updating your DAPLink firmware

You can update the version of the DAPLink firmware your device uses.

If you have a BBC micro:bit, please visit this page for more information on updating the micro:bit Firmware
