How to enter S32G3 Low Power mode

yiguangtang — Fri, 26 Jan 2024 01:29:36 GMT

As for S32G3, we want it to enter the low-power mode at present, please tell us how to operate this specifically, and please also give the support:
1. If you want to enter low-power mode for the G3, determine whether you need to configure all A and M cores separately before entering low-power mode
2. Can relevant Settings be set from the Mcal of Eb? If so, are there relevant documentation cores and reference routines (Currently I can see in the MCU module of EB that the operation mode is RUN/CORE_STANDBY/SOC_STANDBY, and it seems to be related to the selected core)
3. How to set the wake up source after sleep for future wake up function

Hi,

Below will be some comments on regards of your questions:

Q1. If you want to enter low-power mode for the G3, determine whether you need to configure all A and M cores separately before entering low-power mode

A1 >> The following is told under the S32G3 Reference Manual [Page 1699, S32G3 Reference Manual, Rev. 3, 02/2023]:

"It is necessary that the main core has completed all the operations pertaining to other (application cores) and is the last active core before initiating the standby entry sequence."

For which, all other cores (aside from the main core) should have already been shutdown, since the expected steps to be followed are [Page 1697, S32G3 Reference Manual, Rev. 3, 02/2023]:

Q2. Can relevant Settings be set from the Mcal of Eb? If so, are there relevant documentation cores and reference routines (Currently I can see in the MCU module of EB that the operation mode is RUN/CORE_STANDBY/SOC_STANDBY, and it seems to be related to the selected core)

A2 >> All settings should be available under the S32G RTD packages. As for specific documentation on how to manage the routines, we see the following is available:

S32G: M kernel Standby demo and how to porting to ... - NXP Community

Q3. How to set the wake up source after sleep for future wake up function

A3 >> The following information is provided under the S32G3 Reference Manual [Page 968, S32G3 Reference Manual, Rev. 3, 02/2023]:
