using USB H1 on the imx6solo custom board

[kimhansung]

My kernel base version is 3.10.53 and the BSP is made by using yocto project build system. The BSP was working well.

Additionally, I were trying to add USB host 1 for imx6solo custom board.

So, the reference device tree files of sabareauto ware used for usbh1.

And the pins such as USB_H1_DN, USB_H1_DP, USB_H1_VBUS  were assigned exactly. But we didn't use USB_H1_PWR and didn't control VBUS pin. The VBUS pin just connected to 5V source.

I think that It was no problem.

Finally, The EHCI host controller was checked in my menuconfig.

I have tried to boot my custom board, but my board seems like not to recognize USB salve device(AX88772A USB-to-Ethernet Adapter).

I think that the following log said some issue of USB related.

Could anyone check it and give me some idea to solve?

Thank you for your response of my problem.

I modified to the kernel configuration related to USB driver as the below.

But, I got the same start-up log with no recognize USB.

is It enough for using usbh1?

I think that the below log message is related to vbus voltage.

Actually, I had a imx6qsabre sd evk board. And I could find a different log message about the vbus.

Do anyone have idea the below log what is different?

The below log message of my custom board is related to USB Host 1 operation or recognition?

platform usb_otg_vbus.29: Driver reg-fixed-voltage requests probe deferral

Because you defined the regulators for usb_h1_vbus and usb_otg_vbus in <your_board>.dtsi file.

[kimhansung · Accepted solution]

Thank you for your help.

Actually, The VBUS for usb_h1 was connecting to 5V source directly.

So, I modified the reg_usb_h1_vbus  with "regulator-always-on". in the *.dtsi file for my custom board

After modified, usbh1 worked very well.

[jimmychan]

May be some related USB driver not being loaded. Please check it in the kernel configuration and then build it as "Y", not "M" (module).
