How did you get a dev kit with ES silicon (vs. ES2)? All of the A10 SoC dev kit designs on rocketboards.org target ES2 silicon as far as I can tell. I've been working with the GHRD project from rocketboards, which has the F2SDRAM interface in port configuration 3 with F2SDRAM 2 connected at 128 bits wide to a JTAG to Avalon master bridge.

We ordered an A10 SoC dev kit and have been waiting patiently to receive it. Ours will have ES2 silicon and I was not even aware that earlier kits with ES silicon had ever been released to the public.

Sounds like you were a very early adopter and are paying the inevitable price for that. Altera should definitely step up and get you a new kit with ES2 silicon as soon as they're available (in a few weeks so we've been promised).
