On my Raspberry Pi i have installed Developer Preview 5.1 and one application that works as default.
Now is Developer Preview 6 coming. For now to make OTA Updates i recieved a warning, that i should update the OS version.
I have created empty bundle with developer preview 6 and in OTA Updates i have started new Update with it. After some days my Raspberry has still preview-5.1
I have created apk for my app, zipped it, uploaded with last preview version (only last version can be selected in console) and have started new update with it. Update has never received the Raspberry.
Raspberry SD Card has 8 GB, Image is 4 GB big.
On https://developer.android.com/things/console/index.html is said, that system image updates with console OTA Updates are possible. Is it so? What have i maked wrong?
