Hello,

I'm trying to get one of the tutorial 2 .bof files to work nicely with its corresponding (or any) py file on my machine. Most recently, I've really been trying to get tut2a.bof to work with tut2a.py.

After having to correct minor things in the py file (like making sure that the python script was trying to communicate with registers that actually existed in the design) I've hit a road block.

No matter what I do, I can not get tap-start() to run. The error that I keep getting is below:

=========================================================
arccadmin@pestcontrol:~/Desktop/10gE_tut_FILES$ python2.7 tut2a.py

I've looked into upgrading borph...but as far as I can tell, I'm already up to date with corr, tcpborphserver, and tgtap.

Any ideas? I've attached the .py file that I'm trying to run to this email, though it's pretty much identical to the one I downloaded from the tutorials online.
