Hello, I'm trying to use the OTG USB port that is next to the Ethernet connector as a USB host device, so that I can plug a USB stick into it rather than using it as a network connection to a PC. According to the docs this is supported, but it doesn't seem to be working for me. Is there some sort of configuration that I have to do (either GPIO pins or special kernel build options) in order to make this work?
I believe that the micro USB is not supporting Host mode, only the normal USB port is supporting Host.
This should be possible as controller support host mode, I suspect it should be possible just by altering the dts/dtsi file for usbotg1 to be in host mode.
Hmm, for some reason I didn't get an E-Mail update for the responses. Thanks folks, I'll try the OTG adaptor first as that seems simpler than playing with the DTS compiler from what I remember.
You don't need to change the DTS/DTB. The fifth pin in the uUSB connector will change the USB port mode automatically. That's the purpose of the OTG adapter. This is the official adapter; any other adapter will work btw.
