How to enable the OTG 2 and set device mode on i.MX6 UL/ULL

[viking_yuan]

For OTG 1, both device and host modes work fine. OTG 2 host mode works, too. But I can't see the USB mass storage if OTG 2 is set as a device.

Thanks igor!

So, if I want to use both device and host mode, I should configure it as below, correct?

dr_mode = "otg" /* Set controller as otg mode */

[igorpadykov]

right.

Best regards

Hi viking_yuan

one can check if usb mode is configured properly in dts using

sect.4.9.9 Changing the Controller Operation Mode   i.MX Linux Reference Manual​
