Default Spartan 3 Starter Kit .mcs upload problem


Hi,

I have a problem in uploading an .mcs file from the Spartan 3 Starter
Kit reference designs to the flash prom.

Specifically it is the design "Micro Blaze Master System" from

http://www.xilinx.com/products/board...ce_designs.htm

I use Impact from the ISE WebPack vers. 8.1 and follow the standard
prescription for uploading .mcs files which - for example - always works
with the factory default .mcs or the .mcs I produced from own designs.
Concretely I assign the chosen .mcs file to the flash prom with Impact,
select the prom type xcf02s and then execute "program" with "verify"
selected.

But in the case mentioned above ("Master System") this gives me an error
in the verification phase after the upload. The error is accompanied by
a message "non contiguous address" (or the like).

What could be the reason for this ? Hardware fault ? Incompatibility
with newer Impact ? Wrong procedure on my side ?

To check for hardware problems I tried "blank" with "verify empty" on
the prom with Impact, this went through without error.

I would be very happy if someone could help me resolve this problem, so
that I can test all features of the board with this example design.

Greetings

Jürgen

Default Re: Spartan 3 Starter Kit .mcs upload problem

I had a similar problem with the S3 kit while ago. The problem somehow
disappeared when i did the following:

Decrease the programming frequency, then run a script that blanks flash
and then programms it _twice_ before verification.
