MSD

The interface MCU features an mass storage device (MSD). This makes the development kit appear as an external drive on your computer.

This drive can be used for drag-and-drop programming. However, files cannot be stored on this drive. By copying a HEX file to the drive, the interface MCU will program the file to the device.

Note:

You can also disable the MSD of the kit by using the msddisable command in J-Link Commander. To enable, use the msdenable command. These commands take effect after a power cycle of the development kit and stay this way until changed again.
