Using the --loadlocal usb,flashled will cause the First Boot process to flash the Green Pi LED with progress/problem indicators. This is very useful if the Pi doesn't have a monitor attached. The flash codes are ("." is a short flash, and "-" is a long flash):

  • ..- ..- ..- — First Boot is waiting for an unmounted USB device to appear with the file local-settings.txt on it.
  • ... --- ... — An error was found in local-settings.txt. Errors can include:
    • ssid or password are not specified, or are the null string
    • An invalid WiFi Country was specified
    • An invalid Keymap, Locale, or Timezone was specified
  • -- -- -- -- — WiFi did not connect
  • ..... ..... ..... — WiFi connected
  • .-.-.- .-.-.- .-.-.- .-.-.- — Internet is accessible
  • -.-.-. -.-.-. -.-.-. -.-.-. — Internet is not accessible
  • ..-. ..-. ..-. — Waiting for a DHCP-assigned IP address
