Hi,

I would like to know, what are the steps to wake-up and to send to sleep the platform ?

Second question, it is for the auto start of the application. I try to put in the adef the line " start: auto", then i deployed the application, but when i restarted the platform, the application didn’t start auto.  
Are there requirements to be able to make it?

Thank you

David

Hi David.

You can find some power management documentation at [legato.io/legato-docs/15\_08/ … \_mgmt.html](http://www.legato.io/legato-docs/15_08/how_to_power_mgmt.html). That’s a good place to start.

As far as your application not starting, can you post some logs from your legato startup?

Thanks,  
Andrew

Hi Andrew,

Thank you for the documentation.

For the logs, there are just logs of the “le\_mem\_ForceAlloc()”, i don’t think that it’s interesting.
