Using Avnet AvProg for Xilinx® Spartan®-3A Evaluation Kit under Linux
Avnet has made a very cheap ($49) Xilinx Spartan 3A Eval kit, with a lot of nice features.
The FPGA is not programmed through a JTag, but through some "homemade" USB connection. Avnet has made a tool called AvProg for this connection, which is Windows only (shame on them!) :(
It is, however, fairly easy to get working under Linux using Wine.
