- -c Check for firmware update and exit.
- -w Fetch image and exit, do not perform flash write.
-
-Options:
- -d Do not detach from terminal.
- -n Do not backup configuration.
- -v Skip verification of downloaded image.
- -y Assume defaults for all questions.
-
- -s <seconds>
- Sleep given amount of seconds before starting flash write.
- If ommitted and '-y' is not used, 5 seconds are assumed.
-
- -u <url>
- Fetch firmware image from given url. A file "md5sums" is expected
- in the same remote directory. If there is no such file, use -v to
- suppress verification.
