#Command: shutdown -h now doesn't work

##Question

<i>
"Everytime I try to power down my Arietta via __shutdown -h now__ or __halt__
it reboots immediately afer it shuts down. What is my mistake? Or has my board any defect?
Or how to power ist down properly ?"
</i>

##Answer

On the Arietta, the Shutdown line is connected on the power regulator 
enable so to be able to put Arietta in sleep if you use a battery for the RTC.

In order to shut down Arietta properly the right command is hence

<pre class="minicom">
# shutdown -h -H now
</pre>

In this way the shutdown command will not lower the shutdown line and you 
can safely remove power when the board halts.

Without the -H the shutdown line will lower at the board halt 
bringing down the 3V3 voltage so you are doing a very hard reset 
only (useful some time).
