I suggest building the applicaiton together with legato.cwe image:

> [@Application no longer available after a certain time](https://forum.legato.io/t/application-no-longer-available-after-a-certain-time/4546/5):

> It is possible to get rollbacks even after an application is marked good. The only way to completely remove the possibility of your app being removed is to compile a new ‘master firmware’ which includes your app.

> [@Flash size wp7607](https://forum.legato.io/t/flash-size-wp7607/3805/35):

> you can go to legato-19.02.0/modules/WiFi/wifi.sdef, under “apps:” section, add e.g. $LEGATO\_ROOT/apps/sample/helloWorld/helloWorld.adef [image] Now the new app will be included in legato.cwe. Please also note that the max size for legato partition is 8MB.
