Hi Joel,

The one I'm using for rtems tests is this 
(http://microzed.org/product/microzed). I have the 72020 version. We 
also use the Picozed (http://picozed.org/product/picozed) which is a 
similar product, but brings out more of the IO (including some 
high-speed serial ports), while dropping the on-board peripheral 
connectors (ethernet, USB, SD card). It can also host a bigger FPGA 
(72030). We have built a couple of motherboards to host the picozed and 
provide these interfaces. The CPU is the same on all of them, dual-core 
Arm Cortex A9's, and they all have 1GB DDR4 memory and of course the 
FPGA fabric. They all have a JTAG connector, but you can also program 
the fabric through U-boot.

The microzed is really convenient, because all you need besides the 
board is a micro-USB cable, which provides power and a serial console. 
so your full development system easily fits in your briefcase :)

I think they are a control system designers dream :)

Pete.
