You can build the legato.cwe with all the applications together.

> hi @jyijyi, Thanks for your help earlier. I was able to build \<legate.cwe\> and \<system.wp76xx.update\> file using make wp76xx command. Also I was to add myCustom.adef file and build separately with command: mkapp -t wp76xx apps/sample/myApp/myCustom.adef Now, I am trying to add myCustom.adef to build with make wp76xx command, so that I can create \<system.wp76xx.include.myCustom.update\> file. Is there a way to do it? Could you please advise which file I need to modify? Thanks.

And then you can upgrade the legato.cwe by airvantage.
