nRF Connect for Desktop reports "Connect a Nordic development kit"

[Christopher Hunt]

Hi there,

Having just migrated from an x86 Mac to an M1 Mac, I'm now having difficulty getting the programmer app of nRF Connect for Desktop to detect a device. When I attempt to, it asks me to "Connect a Nordic development kit" to your computer. I've got a number of these installed at /opt/nordic. Here's what is reported in the log window:

18:19:18.153

Failed to get the library versions: JLINKARM_DLL_COULD_NOT_BE_OPENED

18:19:18.346

Application data folder: /Users/huntc/Library/Application Support/nrfconnect/pc-nrfconnect-programmer

18:19:20.205

Error while probing devices: EnumerateWorker json error

Any ideas? I've installed nrfjprog and jlink. I can also flash to my device via other means, so the device is indeed there.

Thanks!

Concerning the PPK 2, I did the following changes on my side, and it worked. I am not really sure what the principal reason was, why it started working. 
My setting: I am on M1 (2nd. generation if that matters), have an nrf5340 and a PPK II I am using for power measurements. 

- I disconnected the nrf device

- I downgraded the nrf desktop application from 3.9.1 to 3.8.0. Why? because while spotting the log file it is printed there only the supported engine is nrf connect ^3.8.0
- I then connected the PPK2 to the usb3.0 port and every thing started working
