Try reinstalling JTAG driver.. That helped me with this kind of a problem.
Best,

This is the sort of thing I get when I have code that's running with
interrupts, or something else that the SAM-ICE device doesn't disable,
and I attempt to program the device.
When in doubt: Disable boot options (usually via jumpers) 'til you can
get back to just the "ROM Boot" prompt on the debug console when
you
power up.

Dear senior members,
I am new bie to ARM7. I have two similar devices having at91sam7s128 controller
on it. I have the firmware, code written in 4.4 version of IAR. Intially it was
progrmming fine. I tried to write my own code and in that process i tried to run
the 5.3 version IAR example on the device and it was working also. The 4.4 code
was not migrating to 5.3 so i replaced the 5.3 example startup file with 4.4
file and tried to program the controller with jlink.
Since than ERROR: Bad JTAG communication: Write to IR: Expected 0x1, got 0x7
(TAP Command : 2) @ Off 0x5.
I comming and i am unable to program the device again. Plz guys it is very
serious issue for me . If some one can please assist me how to remove this
error. Please help.
