Applications_user not installing

I’ve started to play with a bit of C code. Thought I’d start with a simple hello_world app.

I created the app bases on the example_images app, created the application.fam with type EXTERNAL etc.

When I create the updater package my app doesn’t get installed. I even tried copying my app to the application/examples folder. Still the same.

I can copy the compiled .fab file to the sd and it runs fine.

My question is, how do I include my code as part of the firmware build?? I suspect there’s a manifest or something I need to update.

Any help welcome. Can’t wait for better docs.
