How to configure M4 MCU as a wakeup source ?

[vinothkumars]

Hi All,

I am working in Power Management in IMX8QM-MEK. I needs to control the Cortex-A53 using Cortex-M4.

Needs to put on Sleep and wake from sleep using M4 MCU.

I am using SDK_MEK-MIMX8QM. Please provide the configuration.

Thanks & Regards,

Hello vinothkumar,

You could take a look at the low-power suggestions from application note AN12195, available on the following link:

Will you please provide your input,

Wake sources

The Integrator must disable the appropriate wake sources when the device is in suspend mode. Common wake sources include heartbeats, modem, Wi-Fi, and Bluetooth. The only valid wake source must be an interrupt from the VMCU to wake up the SoC. This assumes that the VMCU can listen to the modem for remote wakeup events (such as remote engine start). If this functionality is pushed to the AP, then another wake source to service the modem must be added.

Thanks & Regards,
