Memory Allocation Memory partitioning between the AI Pyramid system and hardware acceleration resources is defined below:
4GB variant (2GB + 2GB): 2GB allocated to system memory; 2GB reserved for hardware acceleration tasks including NPU compute and video encode/decode.
This partitioning scheme ensures stable system operation while reserving dedicated memory for AI inference and multimedia processing.

I2C Bus Notice Avoid accessing the RTC chip during microphone recording, as this may cause unstable behavior on the SYS_I2C bus.

RTC Clock Notice After external power loss, the onboard RTC clock module retains timekeeping for up to approximately 20 hours.
