AM6422: R5F low power

Part Number: AM6422
Other Parts Discussed in Thread: AM62P

Tool/software:

Hello,

    We plan to use the R5F core for development and want to use low-power mode. Can you provide information about low-power consumption? It would be best to know the operating instructions on how to put the R5F core into low-power consumption and wake it up to work? It would be even better if there are relevant examples!

    Hello,

    AM64x is capable of Low Power Modes (ie low power state of the whole system), not just the R5F core. But, AM64x Low Power Modes do not have software support and are not planned to be supported for as of now. The drivers to enable a low power mode either do not exist or not validated for the SoC.

    It might be possible to put the R5F core into WFI (Waiting for Interrupt).

    What SDK are you using? Linux or MCU+?

    Thanks,

    Anshu

    Hello,

    Thanks for your reply! I am currently using SDK8.06. Our expected solution is to use both Linux core R5F, R5F for sampling, and Linux for 4G communication to send data. When you say it is not currently supported, do you mean on this SOC？ Are there any other series of SOCs that support this?

    Hello,

    Yes, AM64x only has one whole SoC Low Power Mode which is Standby, but as mentioned, there is no software support for this.

    The AM62 (AM62x, AM62A, AM62P, etc.) Family of devices all support Low Power Modes and have software support for the Low Power Modes.

    AM335x also supports Low Power Modes, but they are currently being debugged in the recent software release.

    Best Regards,
