A20-SOM is small 80x55mm module with A20, Power managment and DDR3 memory only. We announced the prototypes early in September and were working on the software support.
We build also A20-SOM-EVB which is low cost two layer board and allow different A20 solutions to be rapid prototyped and tested.
On A20-SOM-EVB we put two new peripherials: Gigabit Ethernet and 2Mpix @30fps camera.
The Gigabit Ethernet gave us a little bit of troubles at the beginning as the Gmac pinmux was quite different than Emac, but now it works.
What is a bit dissapointing is that Gigabit Ethernet can’t achieve more than 330Mbit/s transfer with the current state of the drivers, there were few comments that this may improve a bit later, but ARMs seems not quite capable with Gigabit Interfaces if you read for other popular ARMs like imx6 also can’t have full throughput of Gigabit Ethernet.
What Oliver Schinagl point out in #linux-sunxi IRC channel is that A20 emac and gmac share different multiplexing on different ports and use different registers, so it may be possible A20 to have two Ethernet ports one 100Mbit and one 1Gbit as same time, but this nobody try yet as no hardware to check.
Sure with A20-SOM it would be easy to modify the current EVB and to add second 100Mbit Ethernet interface and to try if it works.
Last thing we fight now is the camera, it is GT2005 and supported in Android but the support in Linux is not complete, nevermind we are going to run A20-SOM now in production and deal with the camera later as at hardware level everything seems ok.
So we are going to rework some mistakes we found on the prototypes and will run production, so in November A20-SOM should be ready in stock.
