nRF51 DK J-Link Connection Problem

[jgassel]

I am having an issue programming my nRF51 DK through IAR. I am able to compile and build the project, but it gives the following errors when I try to Download and Debug:

I can see the USB device perfectly fine from the nRFgo Studio and even program the binary file that I built from within IAR, so the project seems to be set up okay.

Any ideas? Thanks!

Hi,

Your J-Link installation (or atleast the IAR plugin) seems to be quite old. Could you install a newer version from Segger, and make sure to tick the plugin for IAR at the end of the installation?

Cheers, Håkon

I had the same thought. This morning I uninstalled IAR and all of my J-Link drivers. Did a fresh install of each, making sure to let J-Link install the latest 5.10e USB drivers. No luck, still having the same problem.

Can anyone confirm that this nRS51 DK board works with IAR. I am assuming it does since there are example projects built for that configuration, but it would be good to confirm.

I found a work-around for this by connecting my own Segger J-link to debug (P18) connector.
