Hi, Can anyone confirm working operation of USB OTG over a type c phy on an RK3399 at commit 8c2ffd9174779014c3fe1f96d9dc3641d9175f00 (tag: v5.1-rc2). I've got a nanopc-t4 here and when I try to load the g_ether driver I receive [ 6.359280] udc-core: couldn't find an available UDC - added [g_ether] to list of pending drivers I've had a look through the dts and all seems to be in order. USB devices work fine in the host ports and I've confirmed otg mode. root@rk3399:/sys/kernel/debug/fe800000.dwc3# cat mode otg The cable is being detected at plug/unplug as can be seen from [ 1252.479273] phy phy-ff770000.syscon:usb2-phy@e450.2: charger = USB_SDP_CHARGER My defconfig is the standard arm64 as provided with the addition of CONFIG_USB_ETH=m. Any information would be helpful, especially if this is working on other 3399 based boards at the mentioned commit. Regards, Jack. _______________________________________________ Linux-rockchip mailing list Linux-rockchip@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/linux-rockchip
