OTA Firmware Update Scenarios
4/8/2010
Windows Mobile provides a file system that contains multiple packages that can be updated rather than a single firmware. The OEM can create update packages for various versions using Image Update. During the over-the-air (OTA) Firmware update process, packages can be added, updated, or resized because they are dynamically relocated instead of fixed in memory.
Note
Settings updated through Image Update persist after cold boot; over the air provisioned settings persist after a warm boot, but do not persist after a cold boot.
Update packages must be signed, and are typically stored in the OMA DM server in a connected database. The update process is automated, as described in OTA Firmware Update Architecture.
The following sections describe some OTA firmware update scenarios:
- OTA Firmware Update Using a Single Update Package
- OTA Firmware Update Using a Super Package
- OTA Firmware Update Failure Notification
If you want to update multiple ROM packages, you should send a super package that contains multiple update packages that are downloaded as one object.
