nrf9161 DK Board Configurator not connecting anymore/can not program the board

[PPinto]

I have mistakenly disabled Software Debugger (SWD) and wrote the configuration back to the board. Ever since board can not 

(1) Connect and get the configuration data using Board Configurator (v.0.3.8).

(2) Can not reprogram the board using NRF Connect Programmer.

Is there a way to recover the board from this mode.

Hello, 

Sorry for the late reply. What version of the nRF9161 are you using? Do you have access to an external programmer?

Kind regards,
Øyvind

I am running nRF9161-DK v1.0.0. I do not have access to an external programmer. But I do have another nrf9161-DK (But not a cable going between DEBUG Out and other boards DEBUG In)

Hi,

Øyvind is currently out of office so I will handle the case until he gets back.

Could you connect your board to the Board Configurator and ensure that this switch is enabled?

Kind regards,
Andreas

Once that switch is turned off I can not reconnect using Board Configurator and re-enable that flag. I guess the turning off that switch totally dsiconnected the board from communicating even to the board configurator

It just stay like that without giving the screen to turn on the flag

My bad, I was too quick in reading the first item in your original description. I can confirm I see the same window as you after disabling the switch, restarting the application and reconnecting the device.

I will have another look and see if there's any other way for you to recover the device without an external programmer.

Kind regards,
Andreas

Is there a way I can use jupmer wires and connect another nrf9161DK or nrf52840DK and reprogram this board?

Yes, you can program the device using an external debugging probe. What I'm not 100% sure about is how to make it so that you enable SWD on the DK where you've disabled the functionality through the board configurator. You are free to test the steps (and replace the information below with the relevant DK's you have available) to reprogram the 9161DK.

To flash a Nordic Semiconductor Development Kit (DK) using an external debugging probe, you can follow these general steps:

1. Connect the external debug probe to the Debug In connector (typically labeled P19) on the DK using a 10-pin cable. Some DKs also have a P20 connector for custom connections Nordic nRF5340 DK Debug Out.
2. Ensure that the voltage on the external debug probe matches that of the DK. When powered through USB, the voltage is typically 3V Nordic nRF52840 DK Debug Output (you need to check the voltage on the 9161dk)
3. Power on both the DK and the external debug probe. It's recommended to power the DK separately from the external probe Nordic nRF5340 DK Debug Out.
4. When the DK is powered, the interface MCU should detect the supply voltage and switch to programming/debugging the DK instead of any onboard SoC Nordic nRF52840 DK Debug Output.
5. Use appropriate software tools to flash your firmware. For example, if you're using the nRF Connect SDK, you can use the west command-line tool:

   west flash

   If you're using a Segger J-Link, you might need to specify the runner:

   west flash --runner jlink

Kind regards,
Andreas

Looks like Latest board Configurator version 0.3.10 has addressed this. You can close the ticket
