no jlink device found

[stevechen]

I am using the usb port to download an example project to the NRF development kit board, with Keil4. Somehow it keep telling that "No jlink device found", in Keil, the project-->"options for target.."part, I set it to use "J-link/J-trace cortex", is that correct?

Thanks for any help!!

Best,

That should be correct, you also need to click Settings and select the correct J-Link /J-Trace Adapter.

That is correct. Can you see J-Link/J-Trace Adapter SN in "Cortex Jlink/JTrace Target Driver Setup" window?

I have this same problem. I cannot see the SN in the "Cortex Jlink/JTrace Target Driver Setup" window. nRF Go studio can see the Segger device though. (I'm not sure if it's related, but uVision complains about missing software packs which actually are installed in 'Pack Installer'. The project builds without error.)

Experiencing same problem at my end with nrf51 dk.

@stevechen: Did you find a solution to this?

Can anyone confirm that download and debugging with Keil on nrf51-dk and win8.1 machine works fine?

I suggest you create a new question with your setup and what you have tried. It seems stevechen is not responding.
