WP7607 unwanted rollbacks

1

Hi, I have experience unwanted device rollbacks in some cases with WP7607 module. It seems to be related to power down cycles in some environments. Legato system is marked good but rollback still occurs in some cases.

Sometimes device rollbacks to default Legato system and sometimes it has flushed whole system and asks for a new ssh password once I try to connect to it.

What could cause that and how can I prevent it?

Probably this is due to improper power down sequence, you can see here:

Some solution can be putting important file to reserved partition:

Or you can build those your application together with legato.cwe

Or you can put important files together with yocto.cwe:
