:) AVaRICE version 2.0.20030504cvs, May 22 2003 22:39:40

:) JTAG config starting.
:) Hardware Version: 0xc3
:) JTAG ICE: Unknown hardware version

:) Hm..any hit would be appreciated, and why avarice checks the JTAG box version
:)  ?

Well, you comment out the check as such:

and see how things work.
