Flash write protected patition against sudden power loss

Hello,
does legato support any flash write-protected partition against sudden power loss?
Sudden Power loss should not corrupt any data…

When you are referring to data , are you asking about device specific configuration data?
If you use config tree service API , your expectation of protection of data corruption due to sudden power loss will be handled.
you could check App/System configuration in

and
