Hello,

I have a Freescale i.MX 6 Sabre SD board. It is equipped with one Ethernet RJ45 connector. I need to add a second Ethernet RJ45 connector to the board.

The board has a micro-USB OTG port that allow to connect a plugable USB OTG Micro-B to Ethernet adapter like for instance this one: http://plugable.com/products/usb2-otge100

I would like to know if L4Linux might access such a second Ethernet device connected through micro-USB.

Yes, this is possible. But it might not be easy.

Does anyone has tried this before.

Could someone points me to a tutorial or a guide that shows what are the configurations steps that I should follow to build up a working test case.

Unfortunately there is no step 1-2-3 tutorial. What you have to do, is get the USB controller on your board working from L4Linux. You have to pass-through the respective device resources the Linux driver requires and most likely other devices (clocks, GPIO pins) as well. Most likely you have to modify/adapt the driver in Linux.
