Hi Micael,
Could you try to 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. REF

After that I would recommend to open cmd and issue 'nrfjprog -e' to erase all.
Then program a precompiled .hex file e.g. such as: devzone.nordicsemi.com/.../3108.nrf9160dk_5F00_at_5F00_client_5F00_2019_2D00_11_2D00_29_5F00_d3130d77.hex

Hello Martin, hank you for your help. I'm familiar with Getting Started. The USB cable works with Acconeer radar sensor. LED3 is solid green but LED5 is dead. How can the power be on on LED3 and not LED5?

Hi Micael,

Check out what is referred to as Interface MCU, is what I addressed as the "Programmer chip", and right next to it is the LED5.

Please check out our documentation about Getting Started with nRF9160DK.

I would recommend you to try another USB cable as well, and maybe try to connect to another computer.

No tools for current measurement. Jumper is where it belongs. LED5 is not ON. Where do we have the programmer chip?

Hi Micael,

Have you done any current measurements on the nRF91DK?

The symptoms sounds like you are missing the jumper:

There is a LED5 beside the Programmer chip that will light up when you power up the device.
Please tor to turn OFF and ON the DK, or disconnect and connect the Cable.
