RE: [partial-reconfig] Problem with partial bitstream

["Kehuai Wu" <kw@xxxxxxxxxx>]

Hi there:

I have had some problems similar before. The flow and bit stream seems
absolutely normal, but it didn't work on my equipment. I sent my bit file to
avnet and xilinx, and they both said that my bitfile actually worked on
their side, with the bit file I generated, the board I used but only with
different version of Impact. So try ISE 7.1 Impact and see if it helps. I
was using avnet v2 evaluation board.

Subject: [partial-reconfig] Problem with partial bitstream

Hello Group,
How you all doing?

I have a virtex II pro ml310 fpga board in initial stages
of dynamic partial reconfiguration.
I went through all the mails in this group, so that in itself
is a good exposure letting me know a few tricks and
also how far people have progressed with dynamic reconfig.

As happens with every newbie.. I am with my first design and
have problems.

I am with variable led blinking as my first design as pointed
in http://elektronica.ehb.be/reco/Reports.htm.
(I read DPRtutorial but didnt try that example for reasons mentioned
below)

I ran through the modular design flow successfully, and all my
assembled bitstreams work.

But my partial bitstreams do not change the functionality at all.
I saw an mail on this earlier saying that the bitstream could be
corrupted. But I have rerun my flow more a dozen sickening times
and am yet to see any difference.

Since there werent any errors I do not know where to begin now.

My second question. I have a ml310 board, and I do not see any
external pins except for leds as outputs and clocks as inputs.
So I was wondering how people manage for simple designs
on those boards for more pins? How do they connect?
For example, even one more pin, say "Reset" I do not know where to
connect.

And since this is my first design I am skeptical to try a large
design. Can people having ml310 boards offer some inputs.

Thanks and waiting for your reply.
LN
