Ah well, the UDC is the only way to "speak" to the board (no UART), so I don't have any written feedback available. All I have are the logs displayed on the phone's screen in the framebuffer screen. I know there is not panic/crash, as the screen show no stack/panic. I also know that disconnecting and reconnecting the USB cable triggers the logs of the phy vbus detection. >From what I see the kernel is perfectly resumed, ie. key inputs trigger changes on the framebuffer. I have the host side logs : 1035787.154247] usb 1-1: New USB device found, idVendor=049f, idProduct=505a [1035787.154254] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [1035787.154257] usb 1-1: Product: Ethernet Gadget [1035787.154259] usb 1-1: Manufacturer: Linux 4.4.0-rc1 with pxa27x_udc [1035787.170423] cdc_subset 1-1:1.0 usb0: register 'cdc_subset' at usb-0000:00:14.0-1, Linux Device, 9a:7b:ac:1c:65:82 [1035822.149430] usb 1-1: USB disconnect, device number 69 [1035822.149564] cdc_subset 1-1:1.0 usb0: unregister 'cdc_subset' usb-0000:00:14.0-1, Linux Device --- here the board is gone to "Suspend to RAM" --- [1035829.041922] usb 1-1: new full-speed USB device number 70 using xhci_hcd [1035829.172194] usb 1-1: New USB device found, idVendor=049f, idProduct=505a [1035829.172197] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [1035829.172199] usb 1-1: Product: Ethernet Gadget [1035829.172200] usb 1-1: Manufacturer: Linux 4.4.0-rc1 with pxa27x_udc [1035829.187640] cdc_subset 1-1:1.0 usb0: register 'cdc_subset' at usb-0000:00:14.0-1, Linux Device, 9a:7b:ac:1c:65:82 Here the board is back from suspend to RAM. It "looks" as if either it lost its IP setup, or something else ... the final effect "felt" is that "ping mioa701" doesn't work anymore. I can try that on another board (ie. with an UART, ie. a mainstone), but I don't have a working setup for suspend/resume, so it will probably take time.
