Hey there!
I was wondering about the USB3.1 pinout in the EOMA68 standard. In my research on the USB Type C connector I found out that USB3.1 (Superspeed+) has only two differential signal pairs (one for receiving, one for transmitting) but on elinux.org there are four differential pairs for only one USB interface. Are the other two pairs meant to be used by the second USB port or did I miss something?
Thank you very much! Julius Lehmann

two for receiving, two for transmitting, each 5gbit/s for a total of 10gb/sec. the connector and thus the pinouts are rotatable by 180 degrees so the pinouts on the first 12 pins (top row) are *identical* layout to the second 12 pins (bottom row) except in the reverse order. D+ and D- (the USB2 pins) are *missing* on one row of the receptacle so that you don't connect them up twice (which would be bad).
you *may* be thinking of USB 3.0 which is connector-compatible with USB 2.0 and is what you find on most laptops and desktop computers these days:

that is *only* one set of (5gbit/sec) tx-rx differential pairs.
scared me for a minute that i'd messed it up... :)

I just wanted to say, congratulations on reaching 200k. on your campaign funding :)

thanks :) it'll go higher in a big jump once the cards are shipping. i would like the rk3288 ready and proven and the second campaign underway just *before* that happens.
i worked with my friend to assemble the first passthrough prototypes yesterday. lots more to do to finish them off prior to testing.

4gb of ram is available for the rk3288 right? if so then I don't blame you. That will sell pretty well I bet. :)

I am sure you will get it done easily enough. I read though from some of the other people you are sick though...
I hope you feel better.

4GB RAM and 32GB storage? I'm throwing money at the screen why isn't it working? Seriously though how much are we looking at for campaign season?
