Hi,
I am working on NXP S32K322_M7_0 MCU.
I am trying to enter low power mode through Power driver API.
I have two power mode configuration 1. is for RUN mode and 2, for Low power operation, where RTC and i/o wakeup is needed. I am not using any wakeup driver for now, because I expect the MCU wakes up on any interrupt when WFI is executed.
Now, the issue is current reduction is not happening even most of clocks are gated off and the peripherals are DE initialized.
1. When I use CORE_STANDBY mode and enable deep sleep before changing the power mode to 2 from 1. (Its works perfectly and MCU wakes up on RTC alram) but current reduction is not significant.
2. But When I use STANDBY mode then the debugging stops and the MCU looks like stuck somewhere.
Please help me with this.
Hello,
I am not sure if I understood the issue correctly, but:
But When I use STANDBY mode then the debugging stops and the MCU looks like stuck somewhere.
On wake up from standby you are going trough reset, so the debugger will loose the connection if you do not have any special scripts which will reconnect the device after reset.
Or are you referring to low power debug?
Best regards,
Peter
