Error when fetching device versions: readFwInfo error

Hi I've just started developing with the nrf52840 and Ive been following the official documentation on how to use the programmer shipped with nRF Connect.

Unfortunately when I select the device in the respective menu I get the following error and I'm not able to do anythin on the soc.

Error when fetching device versions: readFwInfo error

I'm currently using Linux with nrf connect 3.80 and jlink 6.88a (I've tried with nRF Connect 3.9 but I had the exact same issue).

Has anyone managed to solve this problem?

  • Hi

    Is this in fact an nRF52840 Dongle, or some other third party Dongle? When you connect an nRF52840 Dongle to a computer and select it in the Programmer app (after putting it into Bootloader mode (by pressing the aforementioned "side mounted" button"), it should be found as an Open DFU Bootloader, and described with its address below. Seems strange that it just has 1 number in your case. Can you confirm that the device is in Bootloader mode?

    Best regards,
