AM62x MCU+ SDK  11.01.00
Release Notes 11.01.00

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, A53 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 22.04 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
ECC Functional Test example for single bit errors is added SDL
Updated DDR configuration from DDR configuration tool v10.30 DDR

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.
Feature Module
FreeRTOS AMP support on A53. DPL, FreeRTOS
A53 FreeRTOS AMP examples demonstrating usage of ethernet Networking

FreeRTOS Support on A53

Is Is Not
FreeRTOS AMP support on A53 GPU Support
Drivers listed for A53 in "SOC Device Drivers" section Low power mode support
Ethernet Networking CSI RX Driver
- WiFi, USB, BLE Drivers
- Safety on A53

Dependent Tools and Compiler Information

Attention
It is recommended to use the TIFS version provided with the release for ensuring compatibility between TIFS and device manager. Using the TIFS from different MCU+SDK release is not recomended and may cause TIFS/ DM functionality to break.
