Hello, I’m debugging my application on WP7702 on field, but I’m finding some problems with Legato behaviour. When my app crashes (at least i guess) the entire system is reverted to a legato copy ( a safe one) and i’m not able to get logs about what really happen with my app. Is it possible to disable the fallback legato image? If not… how can forcly sytart the “bad” version to get logs? I’ve tried with “update --mark-good” but it seems have no effect. Regards, Gianmaria

Sdef will not build to legato cwe, you need to port the application to wifi.sdef and rebuild legato.cwe

You can see here [image] Rollback despite system being marked as good Legato Application Framework You can build your app to legato.cwe

Good Idea… i will try… Thanks!

Can you ponint me in the right direction on how to add my app as it was a system app (keep running also on rallback)? I cant understabd where to add in my legato build… Gian

how about adding it in wifi.sdef and recompile the legato.cwe? [image] Flash size wp7607 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.

Unfortunly I’m not using the mangoH source from a bit of time… I followed this help: System Definition .sdef - Legato Docs legato™ is an open source Linux-based embedded platform designed to simplify connected IoT application development It build. Is it the same? Gian

Added $LEGATO_ROOT/apps/Acg/Acg.adef in wifi.sdef #include "$LEGATO_ROOT/default.sdef" #include "wifi.sinc" #include "wifi_samples.sinc" $LEGATO_ROOT/apps/Acg/Acg.adef Dir Acg contains full code (c, api, and so on), but also Acg.wp77xx.update 3)Build legato cwe with “make wp77xx” executed “swiflash -m “WP77XX” -i legato.cwe” from dir myWorkspace/legato-src/legato/build/wp77xx But no app were included in legato running on target… What am I missing?

Solved. My fault. Forget to surround with app: {}. thanks a lot.
