Release Notes 09.01.00

Table of Contents

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 SK-AM62 (referred as am62x-sk in code), SK-AM62-LP (referred as am62x-sk-lp in code), SK-AM62-SIP (referred as am62x-sip-sk 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.
Feature Module
FreeRTOS kernel upgraded to 10.6.1 FreeRTOS
Boottime optimization: Use Authentication type 0 SBL
Boottime optimization: Use BCDMA for DDR to DDR copy during SBL SBL
SK-AM62-SIP support for all examples All
