Dear John,

I'm not sure if your CPLDs has a JTAG port. Most of them can be
programmed via this JTAG port.
I've ported the JAM Player to Linux. Maybe you can use it to programm your
PLD's.
JAM is a new programming language that is compatible with all current PLDs
that offer in-system programmability (ISP). You can find futher
information at the JAM homepage:
http://www.jamisp.com
I use the jam byte code player for in-system programming PLD's on
industrial fieldbus PCI network cards in mass production with a Linux
system. Works very fine :)
Bye
Michael
