Xilinx CPLD flashing typical command line:
Flash a .xsvf file, created by Impact, to cpld:
Nandpro xsvf: filename.xsvf
General XSVF notes:
LPT is not supported for this feature.
Requires additional connections from LPC2148 to the Xilinx jtag connector.
The Xilinx Impact tool is used to create .xsvf files. The Xilinx Impact software
records/redirects cpld operations into a binary file (.xsvf) that can be
processed by Nandpro. IE: Nandpro does not flash .jed files, but .jed files
may be directly converted to .xsvf by Impact.
See the Xilinx Impact tool for more information."
