Power Management through Sensor Processing Engine on Orin NX

[mdc00]

I have a request about the capabilities of the Jetson Orin NX with regard to managing the power states of the SoC via the SPE (System Processing Engine). Specifically, I would like to know if there is support for switching between SC0, SC7, and SC8 power states from the SPE.

From the documentation and available resources, it seems that there is specific SC7-aodmic wake support for the AGX Orin. However, I am interested in similar or equivalent functionality for the Orin NX, particularly for transitioning across various power states (e.g., SC0 to SC7 and SC8) directly through the SPE.

Could you kindly confirm whether this is possible?
Thank you for your time and assistance.

There are only 3 power state in Jetson l4T (off/active/sc7).
Generally, Orin NX has same chip as Orin AGX. Anyway, the pins exported may be different for different platforms. You can check whether those pins listed in “rt-aux-cpu-demo-fsp/doc/aodmic-app.md” are available in Orin NX module.
In addition, SPE can wake the system from SC7. To enter SC7, it should still come from Linux (CCPLEX).
