AM62L-PROCESSOR-SDK: Inquiry Regarding Deep Sleep / Freeze Mode and RTC Wake Alarm with PCF85263 on AM62L3

Part Number: AM62L-PROCESSOR-SDK
Other Parts Discussed in Thread: AM62L

Tool/software:

Hello Everyone,

While working with the AM62L3 processor and currently evaluating its low-power features, specifically the suspend-to-RAM (deep sleep) and freeze modes. During my testing, I encountered issues while using the rtcwake utility in conjunction with an external RTC device, the PCF85263. The system does not consistently wake up as expected when setting alarms via rtcwake, and I am unsure whether the CPU is properly entering the intended low-power state. I would like to confirm whether both freeze and deep sleep modes are fully supported on the AM62L3 platform, and what the expected behavior is when using an external RTC like the PCF85263 for wakeup events. It would be helpful if you could provide guidance on how to properly configure and test suspend/resume functionality. Below attached is the snapshot of the prints that i received while testing .
