nRF9160dk - Cannot connect to target

[enderen]

I'm having issues using the debugger on the nRF9160dk.

Here is the log that is output when I try to program the on-board 9160 with the command, nrfjprog --program <path_to>/build_1/zephyr/merged.hex --chiperase -f NRF91 --snr 960086086 --log

Set-up details:

Running macOS 12.2.1.

Output when I run JLinkExe:

SEGGER J-Link Commander V7.62b (Compiled Mar  8 2022 15:11:09)

DLL version V7.62b, compiled Mar  8 2022 15:11:03



Connecting to J-Link via USB...O.K.

Firmware: J-Link OB-K22-NordicSemi compiled Dec  3 2021 15:46:55

Hardware version: V1.00

S/N: xxxxxxxx

License(s): RDI, FlashBP, FlashDL, JFlash, GDB

VTref=3.300V

When I run the 'connect' command in JLinkEXE, I get the following error: "Cannot connect to target."

Things tried so far:

• Tried to program other targets (external to nRF9160dk using "Debug Out" connector, and the on-board nRF52840 
• Upgraded J-LINK DLL to latest (V7.62b)

This feels like it might be a hardware issue, but it would be nice know for sure. I've seen in other posts that recommend re-flashing the interface MCU firmware, but this seems like it only applies to nRF5 dks (https://devzone.nordicsemi.com/f/nordic-q-a/24592/my-nrf52-nrf51-dk-kit-doesn-t-work/96836#96836). Any help would be greatly appreciated!

Hi,

 

The debugger is having issues connecting to the nRF9160.

Have you connected a jumper on the "nRF current measurement" header P22?

 

Kind regards,

Håkon

Thanks for the reply. Yes, there is a jumper on P22!

Everything sounds to be correctly setup, JLink Commander detects 3V, but the logs show no communication with the nRF device.

Have you tried the sequence on another computer?

What happens if you try to recover your nRF9160? "nrfjprog --recover -f nrf91"

 

Have you checked that the "IFMCU DISCONN" switch has not been set to the disabled position?

 

Kind regards,

Håkon
