NRF52840 jlink SWD flash/debug connection in Segger Embedded studio

[AndrewR]

I'm trying to make the initial connection and flash/debug my adafruit NRF52840 express through a Jlink EDU to SWD on the NRF board. I am trying to flash to the board in the Segger Embedded Studio. I have been able to upload some basic code through Arduino IDE and USB but I want to be able to use this for productions boards if everything gets working so I am switching to SWD. The Jlink is showing up as a port under device manager. I cant however see it in the Segger ES. The only target I have access to is the simulator. Ive also tried Jlink command which I think finds the board but doesn't execute any commands. I'm not sure the exact commands needed to determine if the connection is correct. If there any advice on getting the first code on to the board via SWD I would greatly appreciate it.

Hello, 

This sounds like an issue with Segger. Have you had a look at Segger Wiki? What are you getting with J-Link Commander?  In SES, what happens when you go to Target -> Connect J-Link? 

Thanks,

Øyvind

Hi, I dot have that option available. Just target > Connect simulator

Again, that's a Segger issue - nothing specifically to do with Nordic.

My SES shows the J-Link option even with no J-Links connected - so it looks like you have omitted to install the J-Link software.

Do you have any J-link stuff in your Start menu?

[AndrewR]

sorry typo. I don't have that option.

Also I Jlink Commander I seem to be able to connect

Definitely an issues for Segger, then:

My SES doesn't have any "simulator" option - maybe you've installed a "simulator only" version?

Segger are the ones to help you with that ...

[AndrewR]

if it's a Segger installation issue. Do you have installation instructions or a download link for non simulator version?

[AndrewR]

it seems there is an option under project option > debug. for target selection. That needs to be switch to Jlink. It starts defaulted to Simulator. This could be something put into a startup manual that would be very useful. Feel free to share.

What project were you using?

I guess that the Projects in the SDK always have the j-Link connection specified?
