We are trying to enable wake up function from UART1 but I don't know how to do that. After put imx6SL into sleep mode, it will wake up if we send data to uart1 pin.
We did below command execution but still no result
#echo enabled > /sys/class/tty/ttymxc1/power/wakeup
#echo enabled > /sys/bus/platform/drivers/imx-uart/2024000.serial/tty/ttymxc1/power/wakeup
Do you have any suggestion in this case?
