The CPU wouldn't wake up.īelow you can find additional response from AE team: The hub wouldn't propagate resume signalling but seems to signal SE0 instead for another 2.5 ms. After that a 1 us spike can be seen, looking like a tristate with pull-up connected. CPU is in memory sleep, USB wakeup enabled, power control is "auto":ĭevice repeatedly tries to wake the CPU up driving the FS_K state for 2.5 ms. The images below is a failure state at various zoom levels. The blue line is Vbus, yellow is Dp and green is Dm. The USB modem is a high speed device connected to USBH1. CPU is awake, USB runtime power management is enabled. The first picture demonstrates a normal wakeup process. mouse, keyboard) connected to USB_OTG seems to work normally: resume signal causes system wakeup. I have no possibility to connect a different device to USBH1. Mxs_phy bphy: HS device has resumedīut once system goes to suspend it have no reaction to resume signal.
