Это происходит вне зависимости от того, воткнут ли JTAG кабель в плату или нет.

Система - Debian Lenny, драйвер для USB - libusb.
Пробовал на Windows 7 с драйвером windrv - та же ошибка. Так что, думаю, дело не в неправильно установленном драйвере.

Так же пробовал вручную создать цепочку. Добавил файл "xc5vlx110t.bsd" и щёлкнул "Get Device ID":
Выдалась ошибка "ReadIdCode Failed":

INFO:iMPACT:583 - '1': The idcode read from the device does not match the idcode in the bsdl File.
INFO:iMPACT:1578 - '1': Device IDCODE : 00000000000000000000000000000000

Больше всего похоже на неисправную JTAG-цепочку. Проверяйте ее физическую целостность.

Во-во, сколько раз похожие темы поднимались, проблемы типовые:
1) проверить сам программатор, какой он там. USB или LPT;
2) проверить схему на соответствие документации;
3) проверить плату на соответствие схеме;
4) проверить качество пайки, нет ли где непропая или КЗ.
Всё, больше вариантов нет.
