Programming the XP10.
---------------------
For this you need a cable and some software. I've got UrJTAG to work
(with a Lattice parallel cable) under Linux. I needed a patch, which
I've not tried to send out to anyone, but I can dig up for you. (It
seems that I needed another reset of some kind during the detection
process).
Good, that's one thing less to worry about.
Could you send me that patch?
Here are the two patches, one is a slight modification to the source,
and I don't really understand why it's needed. The second adds the
information about the XP10 to the UrJTAG data base.
The patch is based off of the urjtag-0.10 release.
So, download that, apply the patch, configure, make, make install, then:

You will have to change the "cable" command to match your JTag hardware.
You might also have to run as root.
I don't really understand UrJtag fully. The ref_freq parameter changes
the speed at which the programming is done. If it goes to fast (takes
less than 30 seconds) then it will fail. The number I need here seems
to change with the weather?
I hope this makes sense.
Mark.
PS.
Without the patch to the source I get this:
