USB 2.0 OTG port

[gautham159]

I have rock64 board, flashed Ubuntu 18.04 Bionic minimal 64bit Image booting off of sd-card. Updated rk3328-rock64.dts

Code:

&usb20_otg {
    dr_mode = "**peripheral**";
    status = "okay";
};

compiled and updated rk3328-rock64.dtb. Connected usb (type A) cable, rock64 USB 2.0 OTG port - latop. Laptop couldn't detect the usb-serial connection though.


Is rock64 OTG port working? am I missing any steps?

Any suggestion is very much appreciated because otg support is the blocker!!

Thank you in advance,
Gautham
