I have just received nRF52840 dongle and I cannot get it programed. I have tried both west flash and nrfProgrammer from nrfConnect.
I have been developing using nrf52840dk so far, and I have no issue programming the dk.
In nrfProgrammer device comes as Unknown ( shown on attached nrf52840.png) I am attaching the log in a separate file nrfProgrammer.log

west flash output:
-- west flash: using runner nrfjprog
FATAL ERROR: "nrfjprog --ids" did not find a board; is the board connected?
Do you have any suggestion on how can I program the dongle?
Please let me know if you need any other information.
