Set up devices for OS evaluation
Microsoft deploys the Azure Sphere OS on the Retail Evaluation feed two weeks before its release on the Retail OS feed, as described in Azure Sphere OS feeds. By assigning a few devices to a group that receives the Retail Evaluation OS, you can verify that your production-signed applications work with the release before we deploy it broadly.
You can verify applications on devices that are in field or lab test, or in production, by assigning them to either the "Field Test OS Evaluation" group or the "Production OS Evaluation" device group. These device groups are intended for the same uses as the "Field Test" and "Production" device groups, respectively. The only difference is that they receive the Retail Evaluation OS instead of the Retail OS.
To move an attached device into a different device group, use the azsphere device update with the --devicegroupname parameter, and specify the name of the device group to which to move it.
If you created your own device groups, you can change the OS feed they receive by using the azsphere device-group update command with the --osfeed parameter.
Contact your Microsoft Technical Account Manager (TAM) immediately if you encounter any compatibility issues so that we can assess and address the issue before we release the OS software to the Retail feed.
