You're using Ethernut 3.0E, right? AFAIK,tThe AT91R40008 on this board
doesn't have any fuses which may disable JTAG access.

Note, that the JTAG interface is unprotected. Removing or attaching the
JTAG cable requires to switch off the power supply.

PS: If you come to the conclusion, that your board is broken, you may
contact the manufacturer, in this case
