Tool/software: Linux
Hi,
I m using yocto processor-sdk-04.02.00.09. I have tried to enable the USB OTG in custom board.

USB 1 port is working with default configuration.
usb2 is configured in DTS as follows :
&usb2_phy1 {
phy-supply = <&ldousb_reg>;
};
&usb2_phy2 {
phy-supply = <&ldousb_reg>;
};
&usb1 {
dr_mode = "host";
};
&omap_dwc3_2 {
extcon = <&extcon_usb2>;
};
&usb2 {
/*
* Stand alone usage is peripheral only.
* However, with some resistor modifications
* this port can be used via expansion connectors
* as "host" or "dual-role". If so, provide
* the necessary dr_mode override in the expansion
* board's DT.
*/
dr_mode = "peripheral";
};
In Menuconfig I have added the below supports :
+CONFIG_USB_DYNAMIC_MINORS=y
+CONFIG_USB_OTG=y
+CONFIG_USB_OTG_WHITELIST=y
+CONFIG_USB_OTG_FSM=m
+CONFIG_USB_GADGET_DEBUG=y
+# CONFIG_USB_GADGET_VERBOSE is not set
+# CONFIG_USB_ZERO_HNPTEST is not set
There is no voltage in USB2_5V pin.
Please provide the Guidance to Enable USB2 as OTG (MICRO USB TYPE B FEMALE connector)
