Azure Sphere OS version updated to wrong version and I cannot deploy applications anymore


I was running the Azure Sphere Blink1 project template without a problem, both with local debugging and deploying the application.

But then my Avnet Azure Sphere OS updated from 19.10 to 19.11.

But after that I wasn't able to deploy the application over the air, local debugging is still ok.

Your device is running Azure Sphere OS version 19.11.
The Azure Sphere Security Service is targeting this device with Azure Sphere OS version 19.10.
warn: Your device is running an older Azure Sphere OS version (19.11). It has not yet started receiving the available update to version 19.10.
warn: Your device is connected to Wi-Fi. If the over-the-air update does not begin, reset your device and try again.
Go to aka.ms/AzureSphereUpgradeGuidance for further advice and support.

So I reset, waited a while, tried a few more resets, still wasn't able to deploy. I tried the recover command which went well and got my sphere to 19.10 again.

Device recovered successfully.

But still I am not able to deploy the sample Blink1 template image over the air. Any suggestions?


Solution

  • Adding back WiFi settings allowed over the air deployments.

    azsphere device wifi add --ssid . . .
    

    Should have checked that earlier :)
