hi,

 

OTG is functioning by default off of the USB Micro on the Carrier brd

The signals are routed to the q7 connector and onto the Carrier Brd. There is no USB connector on the SOM  itself.

 

For the position char please refer to "DB8074_som_0200_cross_reference" and "DB8074_carrier_0200_cross_reference" on the support server.

 

thanks

Hi,

Does anyone tried USB OTG function yet

I saw the micro-usb port marked with OTG, but when i tried this with my usb mouse, seem no function, and even no power output.

when i checked the schematic, i found U36 and R212 which is used to power the USB OTG VBUS is marked with DNP. seem they are not soldered on the board.

Does anyone know how to enable USB OTG function?

 

PS: seem i only have schematic but no components position char, how can i find components on the real board? does anyone has components position char.

 

Thanks
