Trying to find out 1. bootup time & 2. wakeup time of device after sleep.
Tried echo mem > /sys/power/state for apalis imx8
output : -sh: / sys/power/state permission denied
Is there any other way to put processor in sleep from command line
Welcome to Toradex community.
Could you provide software and hardware versions of your setup?
Hardware: Apalis imx8QM 4GB WB IT V1.1 on eval board 06805227
Hello @ashok.tx Any update about sleep & wakeup functionalities for imx8 board
Sorry for the delayed response.
- bootup time & 2. wakeup time of device after sleep.
systemd-analyze help you to get the boot time statistics.
ok, Thanks @ashok.tx . Using systemd-analyze I get something around 3.8 seconds for kernel and 38.4 for userspace.
Now for putting system in sleep I tried
echo mem > /sys/power/state and the output is -sh: sys/power/state permission denied
is there any work around to put system in sleep and wake it up.
Could you check with the sudo -i and then echo mem > /sys/power/state.sudo -i allows you to login as a root user.
tried with sudo -i but getting the same output: permission denied…
It works smoothly in my setup
