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.

Device and Validation Information

SOC	Supported CPUs	EVM	Host PC
AM62x	M4F, R5F	AM62x SK EVM (referred to as am62x-sk in code), AM62x SK LP EVM (referred to as am62x-sk-lp in code)	Windows 10 64b or Ubuntu 18.04 64b

Features Added in This Release

Attention

DeepSleep low power mode (LPM) is not supported if the DM R5 is used for a general purpose application. This is because when the SoC goes to any LPM, the context of peripherals used by DM R5 will be lost. To use DM R5 for a general purpose application, disable LPM support. Refer Disabling low power mode to know how to disable LPM.
