NRF9161-DK on MacOS JLINK DFU Drive continuously disconnects and reconnects

[adamu]

Hello,

I recently purchased a few NRF9161-DK boards for both LTE and NR+ evaluation.  However, I am unable to run through the initial demo.  The board is discoverable initially, but after going through the Quick Start and programming, the JLINK drive starts continually disconnecting and reconnecting and I am unable to get any data from the Cellular Monitor, etc...

The same thing happened with 2 of the 3 boards I have (haven't unboxed the 3rd yet).  I have tried to 'nrfjiprog --recover', but that doesn't seem to have helped.

I'm on an Apple Silicon Mac (M1) running Sonoma 14.4.1

Thanks,

-Adam

First, use brew to update to the latest version of Jlink.

```

brew install --cask nordic-nrf-command-line-tools

```

[When the development board is connected] then enter jlinkexe to trigger the Jlink firmware update, and it will return to normal after the update.

Hi, I having the same problem (as can be seen in the video below). Disk Utility, as mentioned above, doesn't solve it... I am using a Mac with Sonoma 14.7.

Any other hint?
