About USB OTG Function in IMX8MP EVK

Hi All,

I connected a USB memory to PORT1 of USB Type-C to check the USB OTG function of EVK of IMX8MP.
At first the USB memory worked fine and there were no problems.
Then I connected it to my PC and nothing happened.
Can't it be used as a USB Device in the standard Linux BSP?
Or is it a circuit that the hardware cannot use as a USB Device?

Best regards,

tomo

Thank you for your reply.

I understood that it works with Device by using the gadget driver.
Is it possible to achieve Dual Role operation (Host and Device) just by adding a gadget driver?
If so, is the PTN5110 the only CC controller supported by the standard Linux BSP?

Best regards,

tomo

I checked a similar question thread below.
But that is not resolved yet.
