[imx6ul] usb port 1 could not detect usb hub

Hi NXP,

 

Per our design, USB HUB(GL852GT) and Mirco USB are both connecting USB1.

HW use Jumper to switch one of them.

 

However, we encounter the problem is USB1 could not detect USB HUB but the Mirco USB is OK.

We also test USB HUB to connect USB2 of EVM board and our board, with current BSP FW.

And, USB HUB could be detected on USB2.

 

Does it relate to the iMX6UL-14x14-evk.dts setting?

 

404 &usbotg1 {
405 pinctrl-names = "default";
406 pinctrl-0 = <&pinctrl_usb_otg1_id>;
407 dr_mode = "otg";
408 srp-disable;
409 hnp-disable;
410 adp-disable;
411 status = "okay";
412 };
413
414 &usbotg2 {
415 dr_mode = "host";
416 disable-over-current;
417 status = "okay";
418 };
419
420 &usbphy1 {
421 tx-d-cal = <0x5>;
422 };
423
424 &usbphy2 {
425 tx-d-cal = <0x5>;
426 };

679 pinctrl_usb_otg1_id: usbotg1idgrp {
680 fsl,pins = <
681 MX6UL_PAD_GPIO1_IO00__ANATOP_OTG1_ID 0x17059
682 >;
683 };

 

Thanks,

Jim
