I realised that I had a wrong version of nrfutil and needed to upgrade to the latest. I downloaded the file from here - NRF Util

I followed the instruction on the page to also download commands such as 'nrf5sdk-tools' and 'device'.

The version of pyYaml also needed upgrading to get 'west' working again.

I needed another problem fixing in the meantime as I also had a version of nrfjprog which had some permission issue and could only be operated by sudo. I downgraded the utility to 10.24.0. With this also handled all the boards can now be flashed normally.

No, it seems the board finished flashing but the hex file is never actually uploaded. It seems to me that something is wrong here -

Hello,

[quote user=""]-- runners.nrfutil: Board with serial number XXXXXXXX flashed successfully.[/quote]

This indicates that the board is flashed. Can you let me know if the blinky application is running or not on the DK?

[quote user=""]Error: no such option: --json[/quote]

Is the --json option listed when invoking "nrfutil -h" in an nRF Connect terminal? For example, the output I get for nrfutil v7.13.0 from the nRF Connect terminal in VS Code is below.

PS C:\ncs\v2.9.0> nrfutil -h
nrfutil 

Usage:
    nrfutil [+MODIFIER] [OPTIONS] [SUBCOMMAND]

Options:
      --log-level <LOG_LEVEL>    Set the maximum log level [env: NRFUTIL_LOG=] [possible values: off, error, warn, info, debug, trace]
      --log-output <LOG_OUTPUT>  Set log output type: --log-output=stdout --log-output=file ... [possible values: file, stdout]
      --json                     Print output in a JSON Lines format
      --json-pretty              Print output as formatted JSON
      --skip-overhead            Skip all message overhead when in JSON output mode, outputting only the data part of "info" messages and ignoring the rest
      --changelog                Print the latest changelog entry

      --detect-proxy             Invoke libproxy's 'proxy' utility program to retrieve proxy server info and use it
  -h, --help                     Print help (see more with '--help')
