Hello,
I have some issue with console, I hope you can help me: I am using OMAP3530, and trying to get the omap into retention mode with the cpuidle mechanism. I did the following:
echo enabled > /sys/devices/platform/serial8250/tty/ttyS2/power/wakeup
echo 1 > /sys/devices/platform/omap/omap_uart.2/sleep_timeout
~ # [ 85.006622] omap_device: omap_uart.2: new worst case deactivate latency 0: 61035
[ 85.559844] omap_device: omap_uart.2: new worst case activate latency 0: 61035
I than tried to enter characters on console, but it totally freeze.
I also tried to change it as following:
echo enabled > /sys/devices/platform/omap/omap_uart.2/power/wakeup
but on doing
cat /sys/devices/platform/omap/omap_uart.2/power/wakeup
#disabled
Why is it still disabled ?
Thanks for any suggestions,
Ran
