12 years agoCheck the JTAG connections from your programming header to the device are correct.
Check your CPLD is powered correctly - with the board powered take a multimeter round the power pins (there aren't many). All the power pins must be powered correctly. Is this a board you've built yourself? If so, the programming errors may well be guiding you to a build fault - a solder splash or short.
