Hi Every one,
we have one issue .How to create sysfs entries for power wake up through uart and gpio..
we know the wake up commands but we couldnt able to see the below path imx-uart on my target board . can you help any body that .and how to configure uart and gpio wakeup's on imx6 target board .kernel version is 3.14 we checked device tree there mentioned gpio keys code and uart stuff already is there.
we need any changes for that .can you explain how to create sysfs entry for that.
echo enabled > /sys/devices/platform/imx-uart.'x'/tty/ttymxc'x'/power/wakeup
Hi veeranjaneyulu
for uart one can look at attached Linux Manual sect.22.1.5 Unit Test
for gpio:
linux/Documentation../fsl-imx-gpio.txt
