i.MX8 Low Power Mode:

 

How do you set the i.MX8 to wakeup from sleep from a USB Plug-in event? I've looked at 6.1 in IMXLUG, Rev. L4.9.88_2.0.0-ga, 05/2018, and it only mentions setting the debug UART as a wakeup source. I'd like to have the device wakeup when the USB-C cable is plugged into a host; is this supported by the NXP BSP? I am using the NXP i.MX BSP

4.9.88_2.0.0-ga release whose manifest I used with following command:

repo init -u https://source.codeaurora.org/external/imx/imx-manifest  -b imx-linux-rocko -m imx-4.9.88-2.0.0_ga.xml

My settings used for the bitbake environment were:

MACHINE=imx8mqevk DISTRO=fsl-imx-xwayland ./fsl-setup-release.sh -b bld-xwayland

I built the fsl-image-gui recipe; i have already successfully suspended the device and woke up from debug UART activity.

 

Regards,

Kevin
