The short answer is no. At this time VERA does not run on the ENP-2505. As you note, the ENP-2505 is different from the IXP1200 Evaluation Board. I've taken a close look at the ENP-2505 boards (we have two of them here) and have determined that VERA will need some changes to get it to work with these newer boards. The lack of LEDs or jumpers is no big deal. (There are DIP switches which replace most of the jumpers.) The two big differences that will require code changes are the much larger SDRAM (256MB vs. 32MB) and the fact that the IXP1200 is isolated from the PCI bus with a 21555 non-transparent PCI-to-PCI bridge. To avoid memory windows, VERA maps the entire SDRAM range directly to the PCI bus. For the 32MB evaluation boards, this is fine. However, I don't think we'll get away with that on the 256MB RadiSys boards. (When we put 3 or 4 boards in a system, it eats up PCI address space rather quickly.) We'll need to make a change where only a window of the SDRAM is mapped to the PCI bus. The 21555 non-transparent PCI-to-PCI bridge is a little trickier. However, since VERA already runs on the RAMiX PMC694 (PowerPC based) board with a very similar 21554 non-transparent PCI-to-PCI bridge, VERA already has some of the code needed to support the RadiSys board.

I just start to work on ixp1200. I have only a ENP2505 and I want to use Vera, is that possible. As I see the Vera is for Intel evaluation board.
Thanks.
