Hi all,
i want to use usb in device mode for that i did like below in dts file.
reg_usb_otg_vbus: regulator@0 {
compatible = "regulator-fixed";
reg = <0>;
regulator-name = "usb_otg_vbus";
regulator-min-microvolt = <5000000>;
regulator-max-microvolt = <5000000>;
gpio = <&gpio3 22 0>;
output-high;
enable-active-high;
};
reg_usb_h1_vbus: regulator@1 {
compatible = "regulator-fixed";
reg = <1>;
regulator-name = "usb_h1_vbus";
regulator-min-microvolt = <5000000>;
regulator-max-microvolt = <5000000>;
gpio = <&gpio1 29 0>;
enable-active-high;
};
pinctrl_usbotg: usbotggrp {
fsl,pins = <
MX6QDL_PAD_GPIO_1__USB_OTG_ID 0x17059
>;
};
&usbh1 {
vbus-supply = <®_usb_h1_vbus>;
status = "okay";
};
&usbotg {
vbus-supply = <®_usb_otg_vbus>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usbotg>;
dr-mode="host";
output-high;
disable-over-current;
status = "okay";
};
My log when i am installing modules.

Solved! Go to Solution.
Hi Qinghua Zhu,
for my board i need to do only file=/dev/mmcblk2p1.
I found the problem.
In dts file i commented following things after that it is working fine. and usb is mounting in PC.
/*&usbh1 {
vbus-supply = <®_usb_h1_vbus>;
status = "okay";
};
*/
Thanks & regards,
Lavanya
I didn't test your method, below is my script,FYI:
insmod configfs.ko
insmod libcomposite.ko
insmod usb_f_mass_storage.ko
insmod gadgetfs.ko
insmod g_mass_storage.ko file=/dev/mmcblk1p1
Hi Qinghua Zhu San,
Has the issue got resolved?
