Hi Marc,

Have you actually done this and gotten it to work?

Thanks!

We have it working. I say "we" as it was mostly my software colleague's
effort:) Apparently it took him a day or less to port the code from the
appnote to PPC in V4, which we have been using. We are programming Xilinx
Platform Flash on a slave board using this method.

yes, I have ported XSVF player too. was to coldfire embedded linux.
the porting itself is simple, and it pretty easy solution when storage
is readily available. if the FPGA system doesnt run linux and only
has small amount of available ram and no nonvolatile storage and no
network and no high speed connections to any hosts, then its more
efficient to program the XCF from bit file directly as then there is
no overhead of the XSVF involved. this is unfortunatly a bit more
than 1 day of work. well at least when doing it first time. Actually
my first time was almost a month. but that was long time ago
when xilinx had not even published the XCFxxP BSDL files yet.
now its more info available so its a bit simpler to get going.
and yet still Xilinx has not and will never publish the XCF
programming
specifications so its a bit RE and testing involved to get all
timeouts
correctly etc, as there is no reference datasheet for then existing :(
