Hi everyone,
I'm working on the NXP S32G274A-RDB2 board and trying to achieve Suspend to RAM (STR) while a program is running on the M7 core. The program running on M7 blinks the red and blue LEDs alternately until Inter-Processor Communication (IPC) is established.
To test STR, I am using the following command:
echo; date; echo; rtcwake -d rtc0 -m mem -s 10; echo; date
Observations:
- When there is no program running on M7, the above command successfully puts the board to sleep and wakes it up after 10 seconds.
- However, when the M7 program is running, the STR command does not put the board to sleep. Instead, the user space freezes, and the system does not enter the expected low-power state.
Has anyone encountered a similar issue? Is there a known dependency between the A53 suspend process and M7 execution? Any insights on handling M7 execution during STR would be appreciated.
Thanks in advance!
