[saurav-pandya]

Hi ,

I am working on imx8mq customize board. I have got error when we configure as device mode and host.

Device tree configuratrion

&usb_dwc3_0 {
dr_mode = "otg";
//extcon = <&extcon_usb0>;
//dr_mode = "peripheral";
//hnp-disable;
//srp-disable;
//adp-disable;
//usb-role-switch;
//snps,dis-u1-entry-quirk;
//snps,dis-u2-entry-quirk;
//maximum-speed = "super-speed";
status = "okay";

port {
usb3_drd_sw: endpoint {
remote-endpoint = <&typec_dr_sw>;
};
};

};

Dmege error :

usb usb2-port1: Cannot enable. Maybe the USB cable is bad?
[  129.288930] usb usb2-port1: config error

Also I have checked with other cable but same issue.

Hi Saurav, We are also facing similar kind of issues. Can you please let know what was the issue and how it was resolved?

Hi,

That issue in configuration of USB , need to operate GPIO for enable and disable of Device mode and Host mode.

For that we used our custom driver and configure GPIO in that.

Thanks,

Hi Saurav,

Hope you are doing well.

Apologies for delay in response.

1. If possible could you please share the USB schematic section from processor to the USB connector?

2. Rather than using USB cable, are you able to detect the USB OTG port as a device port after plugging in any storage device?

Thanks & Regards,
