- Attention
- Also refer to individual module pages for more details on each feature, unsupported features, important usage guidelines.
- Note
- The examples will show usage of SW modules and APIs on a specific CPU instance and OS combination.
Unless explicitly noted otherwise, the SW modules would work in both FreeRTOS and no-RTOS environment.

Upgrade and Compatibility Information
- Attention
- When migrating from oldder version to 11.00.00, see Bootloader Migration Guidelines for more details
This section lists changes which could affect user applications developed using older SDK versions. Read this carefully to see if you need to do any changes in your existing application when migrating to this SDK version relative to previous SDK version. Also refer to older SDK version release notes to see changes in earlier SDKs.
