Hello Nordic Devzone Community,
My name is Ted, and I recently posted a question here regarding trouble when attempting to flash a Sparkfun Thing Plus nRF9160 board, using a Segger J-Link physical programmer and emulator. This work taking place on an Ubuntu 20.04LTS host, with Nordic's sdk-nrf version 1.6.1 and associated tools installed. At that time the programmer's 'runner' called by meta-tool `west` complained of a missing DLL.
Not sure what changed, as I did not solve that problem nor reinstall any Nordic tools. Today upon retry I find the firmware flash process goes a little further. Can a Devzone engineer tell me whether the following log file points to a specific issue I may fix?

As an anecdote, I am able to flash a Zephyr based application via `west flash` to a Nordic nRF9160DK development board. This board has a JLink programmer+debugger integrated within itself. West's flash runner has actually detected when I have both the Segger JLink connected to the host computer, and the nRF9160DK. In that set up `nrfjprog` prompts me for which programmer I wish to use to flash firmware.
Any help with above log.log file message appreciated!
