Subject: [SI-LIST] Re: PLD programming data
Dimiter, if I understand correctly, you built your own programmer that
resides in an embedded system. It should be straightforward for you to
implement a JAM player, and then you can program any number of JTAG based
PLDs, including Xilinx. Use the free tools to generate the programming
file, transfer the file to your embedded system and away you go.
