I am using IMX8 EVK

flashed Android 11 on SD card, and testing suspend to RAM

device enters suped to RAM and exit OK

but power meaasurments are very hugh (X10 then expected)

according to measurments board 2 HDMI inputs phy are on even in suspend to RAM

1. please advice how to disable that

2. please indicate if Android 11 default image should reach the datasheet suspend to RAM power consumption performance

Hi גנור

higher power consumption may be due to leakage, may be recommended to look

>2. please indicate if Android 11 default image should reach the datasheet suspend to RAM power consumption performance

1. how can I reach lowest power in suspend to RAM using Android + IMX8PEVK?

2. I think most power consumption is due to HDMI PHY, how can I shut it down before going to suspend to RAM?
