Hello,  
any sample on fwupdate api? My intention is to place an update file (legato.cwe cause my app are built during legato compilation) on an http server then download and install the new firmware. Is it possible?

Regards,  
Gianmaria

you can use an unsandboxed application to call “fwupdate” command by system() API.
