Your J-Link device needs to support ARMv8 and you connect it to the Thingy:91 via the "debug in" connector. See the documentation for the Thingy:91 debugging interface and follow the instructions there. Note that you need a 10-pin flat cable to connect to the "debug in" on Thingy:91.

With an nRF9160DK you can debug the Thingy:91 by connecting a 10-pin flat cable between the "debug in" port on the Thingy:91 and the "debug out" port on the nRF9160-DK. No other devices are needed, only a USB-cable to power the DK. See the documentation for debug output on nRF9160-DK here.

If you have a SWD connection on your custom board you can debug the nRF9160 with a J-Link device which supports ARMv8.

Hi Maria,

Thank you for your reply.

I have 3 follow-up questions.

1) Is there any way I can connect J-Link device and debug nRF9160 in nRFThingy91.

2) If I buy nRF9160 DK, do I need to connect J-Link device to debug.

3) If I make a custom board using nRF9160, can I debug that board using J-Link device.

Hello,

The Thingy:91 does not have an onboard debugger. To debug an application running on the Thingy:91 you need to connect an external debugger, i.e. an nRF9160DK or an nRF5340DK. The instructions on how to connect the DK as a debugger is found in the infocenter for the DKs.

Best regards,

Maria
