Error when fetching device versions: readFwInfo error

[pisquo]

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?

Thank you for your reports. We are continuously working on fixing this, but have not yet gotten to the bottom of it, as we're struggling to reproduce it on our end.

Best regards,

Simon

He was able to put the Dongle in bootloader mode but after load again the sniffer hex file I get the same error. Is that normal?

Thanks.

Yes, this is the expected behavior for the nRF52840 Dongle, as the nRF Sniffer application is now running (and using the USB) instead of the Bootloader. You need to press the "side mounted" button to get it back into bootloader mode every time you want to flash it.

Best regards,
