Hi Team,

Would you please teach me How to enter MPU(A15) in idle?

The sample code helps us.

The customer is trying to the device is in low power state. The power consumption is higher than PET results.

It’ seems MPU(A15) doesn’t enter in it. They checked LASTPOWERSTATEENTERED in PM_CPU0_PWRSTST after WFI. . But it’s 0x3 Power domain was previously ON.

How to debug it?

Thanks and Best regards,

We Would like to have a minimum sample code (RTOS or baremetal) to enter/test idle state.

Thanks and Best regards,
