RE: Failed to erase device nrf52840dk quick start

Yep, that did it. The first `nrfutil upgrade device` command did not work. So I went to the jlink configure software and it said that there was no valid firmware on the board. I think it also said that whatever was on the board was from 2021 while the current firmware is from Feb of 2025.

I was able to compile and run the hello world sample and have it print out.

Thanks!

Hello,

If you haven't already, try to use the nrfutil directly from command line to see if you are for instance able to run the following 3 commands (you may also need to install j-link):

If that doesn't work, then try to run JLinkConfig and right-clicking the probe, and then selecting Update firmware:

Normally though, you don't need the Quick start, you may as well just follow: https://academy.nordicsemi.com/ Starting with https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/

I also changed it to vdd. This seems to have the default program work better on the pcb, but it still does not clean. I tried reverting to an old version of the NRF connect software, and that did not work either:

Working in vs code to manually build and flash the hello world code yields this:

Also, when I was installing the Segger drivers, I did select the legacy version update checkbox.
