Hi Weidong,

We are using imx8mm in our project.

But we cannot find any USB driver has "compatible = "fsl,imx8mm-usb",". 

It seems the codebase lacks some USB driver source code files.

The uboot branch we used is "imx_v2020.04_5.4.47_2.2.0".

Could you help to check it?

Thanks.

Hi woody,

    I sent my schematic to your personal email, for you reference.

   The BSP I used is L5.4.24, which is valuable for you reference.

   check it, please!

Have a nice day!

B.R,

Weidong

Hi Weidong, 

Could you please help to check if we lack some USB driver source code files in our codebase?

Thanks.

Hi Weidong

For imx8mm-ddr3l-val.dts, default without extcon = <&ptn5110>; Do you have any idea ? Thanks. 

&usbotg1 {
dr_mode = "host";
status = "okay";
};

&usbotg2 {
dr_mode = "peripheral";
status = "okay";
};

[weidong_sun]

On hardware:

1. USB1---Host

GPIO1_IO10(USB1_OTG_ID) should be pulled down to LOW via 2.2K/3.3K reisgtor. USB1_ID can be left floating.

2. USB2: device mode

GPIO1_IO11(USB2_OTG_ID) should be pulled up to High (via 4.7K resistor to 1.8V). USB2_ID can be left floating.

For software ( in device tree)

See last post, chage USB1 to USB2 node.

have a  nice day!

B.R,

Hi Weidong

I try to pull high GPIO1_IO10(USB1_OTG_ID), but USB still not found.

[weidong_sun]

your USB1 is Host. AND USB2 is device, so you should use USB2 to download image.

[venu_mos]

iam also getting the same issue when i use fastboot on my board can i get any help ?

board: phyboard pollux

soc: imx8mp 

whenever i use fastboot command in uboot shell it gives error USB init failed NO usb device found

any help would be apprreciated.

Thanks

please re-create a case in our system(SFDC) or post on community! Then my colleagues of MPU team will handle it for you.

Thanks!

Hi Weidong

The usb1 for downloading, I changed imx8mm-ddr3l-val.dts, but still got failed.

Hi,

Have you seen my previous post?

-u-boot : imx8mm-evk.dts

-kernel : imx8mm-evk.dts

[Justin_Yeh]

Hi Weidong

Due to our MACHINE=imx8mmddr3lval, so I modify the imx8mm-ddr3l-val.dts. 

[weidong_sun]

yes, right.

[Justin_Yeh]

Do you mean dr_mode is not necessary ? 

[Justin_Yeh]

I pulled high the GPIO1_IO10 and modify the dts. usb still not found...

I designed a board based on i.mx8mm, and the code I gave is what I used. it is no problem.

I have sent my schematic of usb to woody, @WoodyCheng , did you recieve it? if yes, send it to justin, please!

B.R,

Weidong

Hi Weidong

Following is my usb info form uboot, any useful information to you ? 

u-boot=> usb info

[Justin_Yeh]

if we'd want to set two usb ports are device mode, 

we should pull high GPIO1_IO10 and GPIO1_IO11 both, right ? Thanks. 

[weidong_sun]

yes , pull USBx_OTG_ID up to High, please!

[weidong_sun]

Hi,

   if there is no PD chip for USB type-c, and only use USB OTG (or device) mode. modify dts in u-boot and kernel.

---u-boot

&usbotg1 {
status = "okay";
/*extcon = <&ptn5110>;*/
};

--Kernel.

&usbotg1 {
dr_mode = "otg";
/* hnp-disable;
srp-disable;
adp-disable;
usb-role-switch;
*/
picophy,pre-emp-curr-control = <3>;
picophy,dc-vol-level-adjust = <7>;
status = "okay";
/*
port {
usb1_drd_sw: endpoint {
remote-endpoint = <&typec1_dr_sw>;
};
};
*/
};

Try it, please!

Have a nice day!

B.R,

Weidong
