nRF9160DK Revision 0.9 JLINK Error

[John_Turner]

Hi,

I'm trying to update the modem firmware on an nRF9160DK (Revision 0.9) but the board is recognized as "JLINK" not "nrf9160DK". If I try to select the board using nRF Connect for Desktop it generates and error saying no JLINK or Nordic boards could be found. I've tried J-Link 7.66 and 7.86 (latest), and nRF Connect for Desktop is version 4.0 (latest) without success. Any suggestions on what to try next?

Hello,

are you able to see the com port of the DKfrom device manager?

Can you check if nrfjprog is able to see your device with nrfjprog --com? The serial number and COM port of the device should show up if it is able to find the device.

Hi Kazi,

I found the problem. The resistor to the enable pin of the nRF9160 was physically damaged and not making contact. I replaced it and the device is recognized as expected. 

Follow up question, since this board is older (Version B0 of the nRF9160) is it compatible with the latest versions of firmware (Modem, Board Controller, etc.)?
