nRF9160 DK v1.1.0


The interface MCU features a Mass Storage Device (MSD). This makes the Development Kit (DK) 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 (SW10). For limitations on nRF52840 use, see nRF9160 DK board control.


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 DK and stay this way until changed again.
