Can't connect to nRF52840-DK using nRF Connect Programmer

Konrad Adasiewicz

Hi,

I'm using Manjaro Linux, nRF Connect v3.10.0 and Programmer v2.3.3. I'm trying to connect to nRF52840-DK using this software, but I get an error:

14:45:31.110	Using @nordicsemiconductor/nrf-device-lib-js version: 0.4.3

14:45:39.237	Please make sure J-Link Software and nrf-udev are installed. See https://github.com/NordicSemiconductor/pc-nrfconnect-launcher/#macos-and-linux

I can connect to the board using JLink software or openocd without problems.

Can you help me?

    I had older version of this software installed on different PC (same OS) and it worked there. After upgrade I experience same issue.

    Working logs:

    Hi,

    I will report this to the developers. Can you upload logs where you try to open the device with verbose logging enabled? Go to the About tab in the Programmer app to enable verbose logging, and select "Restart with verbose logging". Make sure to disable verbose logging again afterwards, as this option will generate a lot of additional log and create rather large log files.

    Best regards,

    Marte
