nRF9160 DK v0.8.5

MSD

The interface MCU features a 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. The J-Link OB will program the target that is selected with the nRF52/nRF91 switch (SW5). For limitations on nRF52840 use, see nRF9160 DK board control.

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.
