I followed the getting start and managed to configure everything.
When I run
Balena scan --vorbose, balena can find my device (raspberry 3 B +) correctly.
The problem occurs when, after creating an application:
Balena app create myapp
and configuring the operating system based on the app created:
balena os configure <path/balena.img> --app myapp
balena-cli does not display anything when I run whale devices. As if I had not added any apps in the configuration.
However, I noticed that the app was added to the configuration parameters in boot/config.json
At this point I don’t know what to do anymore. Thanks in advance for the help, I remain available.
