sgjava Posted December 5, 2017 Share Posted December 5, 2017 Is there a way to set the OTG port on the Duo to host mode when not using it for power? This way a mini shield is not required for simple projects that power off the bus, but want to utilize the OTG port. It looks like it is possible, see my comments in thread below: Link to comment Share on other sites More sharing options...
sgjava Posted December 5, 2017 Author Share Posted December 5, 2017 OK, I tried to modify sun8i-h2-plus-nanopi-duo.dtb by changing usb@01c19000 status = "okay" and adding dr_mode = "host". lsusb still doesn't list any devices plugged into USB port after reboot.

sgjava Posted December 15, 2017 Author Share Posted December 15, 2017 Look like v1.1 of the Duo will support OTG according to FriendlyArm forum. The 3 I have are v1.0. Link to comment Share on other sites More sharing options...
