PM: noirq suspend of devices complete after 7.256 msecsĮven though the CPUs are up, the system remains in frozen state and the tasks are not restarted. PM: late suspend of devices complete after 0.699 msecs PM: suspend of devices complete after 83.021 msecs Wake on UART worked perfectly.įor wake on lan, please see the terminal output below (after sending the magic packet): ethtool -s eth0 wol echo enabled > echo mem>/sys/power/state ata1: SATA link down (SStatus 0 SControl 300) PM: resume of devices complete after 179.727 msecs PM: early resume of devices complete after 0.547 msecs PM: noirq resume of devices complete after 0.494 msecs The target station address is 0:14:2d:4b:16:3. Sending magic-packet using ‘etherwake’: $ sudo etherwake -i enp12s0 -D 00:14:2D:4B:16:03 PM: noirq suspend of devices complete after 0.838 msecs PM: late suspend of devices complete after 0.638 msecs PM: suspend of devices complete after 158.399 msecs To enable the eth0 as wakeup source: # echo enabled > /sys/class/net/eth0/power/wakeup a/arch/arm/boot/dts/im圆qdl-apalis.dtsiĪlso by default in userspace the wake-on-lan is disabled, to enable the wake-on-lan run: # ethtool -s eth0 wol g You can try enabling wake-on-lan support, changes required to enable wake-on-lan: diff -git a/arch/arm/boot/dts/im圆qdl-apalis.dtsi b/arch/arm/boot/dts/im圆qdl-apalis.dtsi Have a look at the device tree bindings documentation here. I am using the wakeonlan utility from Ubuntu host to send the magic packet to the eval board.īy default wake-on-lan is not enabled, one will need to enable it in device tree. To enable wakeup via UART port: # echo enabled > /sys/class/tty/ttymxc0/power/wakeupĪlso, I was not able to find any info on how to configure the ethernet to detect a wake-on-lan (magic packet) signal. Have a look at this article for information on available tty ports on Apalis iMX6. Please note that the article you are refering to is not applicable for Apalis iMX6. However, I was not able to configure the UART for wake up as the following path does not exist in the rootfs.
