Hi Jason, It looks like you may have built the bof file with an older version of the CASPER tools. We had a similar problem with the infrastructure being held in reset and hence TCPBorphServer timed out on bus requests. Have you pulled the latest version from SKA-SA?
You can try the precompiled tut1 boffile to give us an idea whether the problem is with the CASPER tools or TCPBorphServer.
