Trying to 'deploy' on a Seeed nRF52840

Start with the deployment traceback and inspect flash_nrf.py at line 31, where pynrfjprog.LowLevel.API is opened. Reproduce the deploy attempt with the Seeed nRF52840 connected and disconnected, then determine the required JLINKARM DLL or device setup. Done means deployment completes successfully on the reported hardware.

Hi,

I think perhaps this is a little over my head, but I was hoping maybe you more knowledgeable folks could hold my hand a little trying to deploy OpenHaystack on a Seeed nRF52840.

When hotting 'deploy' I get the following error:

I get this error wether my Seeed device is plugged in or not. Just wondering if I have missed something?
