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?
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.
Thanks, please let me know. I see in the datasheet that the AW-CM276NF has a power-down input pin “PDn”! (see attached pictures).
yes take a look here in the device tree. you could switch of the Power down Pin.
