I have a Cubox_I up and running and a RaspeberryPI with I2S DAC.
Question: how do I invoke a graceful shutdown. Earlier experients with the option ShutDown are bad. Than I can’t get the system up and running anymore. Volumio comes up, but nothing react anymore or Volumio can’t come up anymore and had to flash the image again.
What is the procedure except shutdown the power unit?
Normally the shutdown button in the Web Interface should work.
You should wait a minute or two before you disconnect the power unit from the pi.
You can also shutdown your pi over ssh with the command: sudo shutdown -h now (nothing else makes the button)
For the Raspberry: You can unplug the power supply when only a red LED is shining (= power supply is connected), then the system is not running (30-60 sec after you pressed the Shutdown Button in the Web interface)
