12 years ago --- Quote Start --- JTAG ID code spec'd in JEDEC STAPL Format File doesn't match any valid JTAG ID codes for device. --- Quote End --- Rather than using the .jam file, try using the .pof file. The data sheet for the device http://www.altera.com/literature/ds/m7000.pdf has the JTAG ID codes on page 23. EPM7032S = 0000_0111_0000_0011_0010_0000_1101_1101b = 070320DDh The Quartus GUI has a "JTAG Debugger Tool" that you can use to read the ID code. The programmer essentially does this when you scan the JTAG chain. Until you can read back this JTAG ID, you likely have an issue with the JTAG chain. Probe around with a scope and check out the signal integrity. Cheers, Dave
