Dear all,
I am using armbian Mainline Debian Jessie 4.9.7 and 4.9.12 on a Banana Pi Pro (A20). Coming from legacy and fex, I came a long way learning a lot about Device Trees, Overlays, etc. the last 2 weeks. I even compiled some dev kernels to experiment.
I currently struggle with with the OTG port. I have two devices on the primary slots and need to get the OTG in host mode to attach my third device.
I've read that the OTG is not providing 5V to the device. Therefore, I use Pin4 5V DC and Pin6 GND of the 40Pin header. It works well when connecting Device #3 on USB 1 or 2. But not on OTG. I used dmesg to track devices.
Is there anything I am missing? Do I need to edit armbianEnv.txt with some parameter?
Thank you very much for your help!
