Is it possible to use the Strata flash (U27) to write and read from the FPGA? Means, like an ordinary memory.
The idea is to use this memory instead of the DDR2 device.

Virtex-5 is not a board, but an FPGA family and there are many, many, many things that you can do with an FPGA. With a specific board implemenation you can only do what the physical connections allow you to do.
You have not indicated which one of the many boards with a Virtex-5 FPGA on it that you are planning on, so any answer that you get will be imprecise.
It is very likely that the a Virtex-5 board with a Flash memory on it that is used for configuring the FPGA has the appropriate connections to the FPGA to allow the memory to be read and written. Flash memory is not the same as DDR2 and you will need a controller that understands the read and write sequence for the particular memory that is used.
Flash memory will be significantly slower than DDR2 and if you are constantly writing to memory it will eventually fail as the device are not infinitely writable.

I have the Evaluation board from the university program. Rev A (no other name on it...)
I would like to have the DDR2 device working on it but the MIG does not support my evaluation neither my FPGA.
Moreover, I tried the simulations that the MIG generated but the simulation fails in the initialization phase.
The MIG that I have is the one that comes with the ISE 11.1

The evaluation board could be one of the following (I could not distinguish)
ML505, ML506, ML507
I think is the ML505

Hi, the strata flash number on package is the following:
My idea is to use this strata flash with the FPGA. I would like to write and read data.

Regarding the strata flash life cycle, I will write and read a couple of times. It just to concept prove.
Then I will change a suitable memory.

Don´t you have an example for the Virtex 5? (Like those for the Spartan 3)
This will be a great help. With this example I can use as a base for my own code.
