USB-C Dual Role (OTG) Funtionality

Post by whyphy on 2018-06-15, 05:17

I can't find a block diagram for the pocket, but the x7 datasheet lists 1x USB3 OTG and 3x USB3. Is the USB-C port connected to the OTG port on the CPU or one of the other USB3 ports?

Bump.  I have tried to get this working to no avail.  I have tried setting OTG mode to both PCI and AHCI in the BIOS, but I don't seem to see the UDC device register in linux.  Clearly the SoC has the capability, but it would be nice to know if the either of the two USB post connect to OTG, or if they are host-only.  Is anyone from GPD on here?
