Free Flash PROM programming tool for GNU/Liunx

The flash PROM can now also be programmed using xc3sprog. It has taken a
lot of experimenting to get the PROM programming to work. Xilinx has not
released details of the programming algorithm for these devices in its
datasheets. This means that I cannot be sure that the delays used are
correct. Also verification is not performed.

Negatives aside, this program has sucessfully programmed the Flash PROM
on the $99 Spartan3 Starter Kit.

Great work Andrew.

It seems we've been doing similar things over the last couple of days. I
like your code and the SVF route may be the better way to go in the long
run, as pointed out by Mr. Jacobson.

I'll put my activities on hold for now and put a link on my web-page to
yours.

I had considered the SVF route. The problem is that the SVF player
cannot give meaningful error messages, the SVF player is not aware of
the task in hand. SVF can only report a mismatch between what was read
on the TDO and what it was told to expect.

I have just updated my webpage, adding a link to yours.

I think that would be nice to support SVF too. So that when a new device appears, we can program it ;)

Just had a look at the SVF spec you linked.

I found a link to an open source project that claims to have created an
SVF parser/interpreter:

http://ebsp.sourceforge.net/

So looks like that part is already done for us.
