ncrvi 2025.7.27.1

Check rudimentary information

Determine the number of components returning version information

Example usage

$ ncrvi -h
usage: ncrvi [-h] [-w INITIAL_WAIT] [-p POWER_ON_WAIT] [-P POWER_OFF_WAIT] [-N HOW_OFTEN] [-s SETTLING_DELAY] [-e EXPECTED_COMPONENTS] [-u USER] {this,that}

Determine the number of firmware components that report version info

positional arguments:
  {this,that}           the target to work on

options:
  -h, --help            show this help message and exit
  -w, --initial-wait INITIAL_WAIT
                        number of seconds to wait before starting the tests (default: 1.0)
  -p, --power-on-wait POWER_ON_WAIT
                        number of seconds to wait before powering on the target (default: 5.0)
  -P, --power-off-wait POWER_OFF_WAIT
                        number of seconds to wait before powering off the target (default: 0.0)
  -N, --how-often HOW_OFTEN
                        how often to run the show (default: 10)
  -s, --settling-delay SETTLING_DELAY
                        how long to wait (in seconds) before reaching for the stars (default: 2.0)
  -e, --expected-components EXPECTED_COMPONENTS
                        the success criterion (default: 20)
  -u, --user USER       the user to book the target, etc. (default: None)
