nRF Connect Won't Load 52840 Dongle Memory Layout

[sidney-carton]

Hi Nordic Community,

I am trying to build a network using the OpenThread protocol and the nRF52840 chip. I have several Dongles, but I can't figure out how to flash the OpenThread examples (or any hex file) to the Dongle. I think my problem is with nRF Connect. I am trying to follow the nRF52840 Dongle Programming Tutorial, Adapt a simple example (without SoftDevice), but I get stuck when I "select device". The "device memory map" will not load and the device buttons ("erase all", "erase & write", "save as file", "reset", "write", "read") can't be pressed.

I want to know if I'm using nRF Connect wrong or how I can flash my nRF52840 Dongle.

Here is my workstation setup:

I'm running Ubuntu 18.04 on a x86 machine

I have SEGGER JLink v6.6.4 Installed. I can flash a development kit using nrfjprog, so I know this is working correctly.

I have nRF Connect v 3.3.0 Installed.

I have nRF Connect Programmer v1.3.1 installed

I have followed and verified all the steps in the nRF Connect Getting Started Guide v1.0.6.

This is my problem:

nRF Connect will load .hex files but will not "read", "write", etc from the Dongle. It will also not load the Device memory layout.

Here is a screenshot of the Programmer with the Dongle not loading
