AM62Ax MCU+ SDK  11.00.00
Release Notes 09.02.01

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.

Experimental Features

Attention
Features listed below are early versions and should be considered as "experimental".
Users can evaluate the feature, however the feature is not fully tested at TI side.
TI would not support these feature on public e2e.
Experimental features will be enabled with limited examples and SW modules.
