Apalis i.MX8QM Sleep

I am currently using “echo mem > /sys/power/state” to sleep my i.MX8QM. Are there any other options for additional power-savings? What about components on the SOM other than the i.MX8QM, such as the WiFi-Bluetooth module? Can that be put to sleep?

Hello Dlm080,

the Apalis IMX8QM is not really intended for low power designs for that we have the Verdin family.
I check with the team if there is an easy way to dynamically disable the wireless to save power, other then just disable the wireless driver.

Best Regards,


Thanks, please let me know. I see in the datasheet that the AW-CM276NF has a power-down input pin “PDn”! (see attached pictures).

Hello dlm080,

yes take a look here in the device tree. you could switch of the Power down Pin.


Best regards,
