imx6 uart wakeup

ilyyxfe — Wed, 13 Feb 2019 02:46:20 GMT

i use the imx6sllevk.

i tap the follow contents by shell.

cd /sys/class/tty/ttymxc0/power
echo enabled > wakeup
cd /sys/class/tty/ttymxc1/power
echo enabled > wakeup
cd /sys/power
echo mem > state

the system can go into the sleep mode.

but the whole process going into the sleep mode takes 80ms .

during this time if i sent data to bsp by ttymxc1, it can not stop going to the sleep mode.

i consider wakeup_count can resolve the problem.

how to set it or any other way can stop it?

pls give me advice.
