If you could compile software manually and test it, I can help you with 
creating a port. Not sure I am the best person to do it, but I could help a 
bit.

Well, I would like to be able to work with my S3C2410 based board fully under 
FreeBSD, but I did not succeed yet to build a working kernel/loader for my 
board, even JTAG adapter I got with the board works with sofware running 
under Windows. It connects to parallel port, bears a WIGGLER mark on it, if 
anybody has some experience with it I would like to hear.

That being said, being a bit experienced in some areas, I consider myself only 
a newbie in JTAG area, I would like to ask what are you doing with JTAG? 
There are still areas where one could still discover something new...

Milan
