aliles Posted March 19, 2019 Posted March 19, 2019 I'm trying to get the Orange Pi One Plus' OTG port to function in "otg" or "peripheral" mode. I've modified the device tree configuration to change the "dr_mode" from "host" to "peripheral". This works as long as the Orange Pi One Plus and the device are separated by a hub. If directly connected via an OTG cable/adapter the device instead charges from the Orange Pi One Plus. I assume this would be due to the OTG port acting as a power source rather than a power sink. However, after experimenting I've been unable to find a device tree configuration change the role of the vbus. Does anybody have any advice?

aliles Posted March 20, 2019 Author Posted March 20, 2019 Well, that's starting to make a lot more sense. Thanks @martinayotte
