    lyf4> It will be great to get the information on this.

First, you need to find out the JTAG ID of the device and its IR-Len. Enter
these values in devlist.txt and make xc3sprog read your changef file, either
by recompiling or by putting the file in the default places or by setting up
an environment variable to that file. Read the doc for more information.

The second, probably bigger step is to check the algorithms used for the new
device. Probably it is similar to older devices, but maybe some subtile or
bigger changes are needed. You have to extend the algorithm or in case of
bigger incompatibilies write a new algorithm. This will need testing and
probaby debugging with a real device. As I don't have such a device, I can't
write these changes, but I can try to help you by explaining.

Hope this helps

PS: Also mailing to the mailing list for later reference...
