- 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.
