Thank you very much for this further information!  Unfortunately, it
is not possible to get to the View->Debugger Internals menu with
H-JTAG selected as the debug channel. ADW displays the message "H-JTAG
server is not ready", and will not continue with ADW startup until
H-JTAG is responding correctly. Since IAR also reports the exact same
error message when the H-JTAG RDI debug channel is selected, I assume
the error message is generated by H-JTAG itself. The H-JTAG server
itself also generates an error message on startup, so everything comes
back to H-JTAG and the Olimex Wiggler.  Since your Wiggler does seem
to work OK with H-JTAG, there must be a difference in these Wiggler
implementations causing the problem. Since Tsvetan has already
indicated that he knows what the problem is I hope that he and
twentyone can get together on a solution? It would be a great addition
to our community if H-JTAG and the Olimex Wiggler can be made to work
smoothly together. It would also be really great if H-JTAG would also
work with the EasyICE JTAG pod, since it is almost, but not exactly,
the same as the Wiggler. I tried to set up an EasyICE using H-JTAG's
user defined configuration option, but the correct pin assignments are
not available in H-JTAG's user defined menu.


HAPPY NEW YEAR!!!
