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?

    One thing I noticed also is that the J-Link v758b(32bit) was installed on my 64bit OS!!!

    Hi Simon

    I have now tried this on another PC with Win8.1 and the same problem come nRF BLE want to program the device but then fails! Please can you try a fresh install on another machine and see what is going on! I am surprised that you can't reproduce this. We are stuck now and cant continue developing any further. We will have to soon decide to use this chip in our product. So any help you can provide would be useful to you and us not forgetting a lot of people who are having this issue. Please try to recreate the issue. Some time when you have all the software installed and done a lot of setting on your pc as your developing then you can't recreate it but when you have a fresh PC the problems there...

    Hoping you can help..

    Regards,

    Raj

    I'm getting the same error with Programmer v3.0.3 and the nRF52840 dongle:

    Error when fetching device versions: readFwInfo error (Origin: "Error when starting nrfdl_fw_read_info")

    What I did was program the firmware for the wireshark sniffer sniffer_nrf52840dongle_nrf52840_4.1.0.hex.  After doing that, I could not longer program firmware.
