Hi,

You can check the command supported by nrfutil nrf5sdk-tools with this command:

>nrfutil nrf5sdk-tools --help
Usage: pc_nrfutil_legacy_v6.1.7.exe [OPTIONS] COMMAND [ARGS]...

Options:
  -v, --verbose            Increase verbosity of output. Can be specified more
                           than once (up to -v -v -v -v).  [x>=0]
  -o, --output <filename>  Log output to file
  --help                   Show this message and exit.

Commands:
  dfu       Perform a Device Firmware Update over serial, BLE, Thread, Zigbee
            or ANT transport given a DFU package (zip file).
  keys      Generate and display private and public keys.
  pkg       Display or generate a DFU package (zip file).
  settings  Generate and display Bootloader DFU settings.
  version   Display nrfutil version.
  zigbee    Zigbee-related commands and utilities.

It seems that passing -o filename should make it log to the file. I haven't tested logs with nrfutil dfu serial, so I am not sure what gets logged there.

If you want to debug serial DFU, you should use the bootloader with debug version like pca10040_uart_debug to get the log instead of the log from nrfutil.
