There is no problem to using board
However, I wanna know why the ‘USB Type-C’ is on the board and why the error like the title occurs.
I wonder why this is happening.
please let me know.
Hi, @acidpero, how did you get that message?
After booting up, I only get this:

Hi again, @penguin
I got Firefly:Ubuntu 16.04 image
[Here!](https://drive.google.com/drive/f … gAqAdXBsaG9NMEl5bm8)
and flashed the image with the upgrade tool.

when boot without connecting the USB Type-C port to the Host PC, I got the same message like yours.
But when I boot them with both connected, I got the following message.
# Kernel Log, filtered (fusb302)

I would like to know why there is a USB Type-C port other than flashing.
The board can be served as USB widget, where the Type-C port will be in device mode.
But by default, both the board and PC are in host mode, which makes no sense when
connected together, therefore the fusb302 chip reports ROLE_MODE_NONE .

我的也这样，不知道啥问题
because firefly_rk3399 use the type-c by otg mode,but there is different both otg wire and defualt wire. so if you want to use the default wire,you can chang the otg mode ,modify dts,chang the &&usbdrd3_0 to &u2phy0
&usbdrd3_0 { status = “okay”; //extcon = <&fusb0>; extcon = <&u2phy0>;}; &usbdrd_dwc3_0 { status = “okay”; dr_mode = “otg”; /* Micro USB3控制器的dr_mode配置为otg / maximum-speed = “high-speed”; / maximum-speed 属性配置为high-speed / phys = <&u2phy0_otg>; / phys 属性只引用USB2 PHY节点 */ phy-names = “usb2-phy”;};
