All,
I recently tried to use tutorial 2 to do some troubleshooting of
10GbE ports on a couple roaches. I found a few inconsistencies in
the file links that I thought I would point out.
Mainly, there seems to be several combinations of the bof file, py
file, and mdl file that work directly.
For instance, I downloaded tut2b.bof from
here:
https://github.com/casper-astro/tutorials_devel/tree/master/workshop_2011/roach_tut2_10GbE
and tut2b.py from here: https://casper.berkeley.edu/wiki/Tutorials
and tut2b.mdl from here: https://casper.berkeley.edu/wiki/Tutorial_10GbE
The only problem with this combo is that line 21 in the .py file reads:
tx_snap = 'snap_gbe0_tx'
but there's no "snap_gbe0_tx' when you do a listdev. Looking at the
mdl file, I found that line 21 in the .py file should read:
tx_snap = 'snap_10gbe_tx'
Changing that seemed to do the trick, and this combination got me to
the finish line the fastest.
Then, I downloaded tut2b.mdl from the main tutorials page and it has
the name "snap_gbe0_tx" that the .py file was originally looking for,
but I didn't manage to find a bof file that worked with that .py file directly.
I guess the bottom line is that someone should check out the various
links for tutorial 2 and make sure they are all consistent, and that
they all play well together.
Thanks,
Jason

Good catch!
Yeah, something's suspicious here. Here's the definition for that
init function as it is currently on github and also on pypi...
def __init__(self, host, port=7147, tb_limit=20, timeout=10.0, logger=log):
So you should just have to specify the ROACH board.

replacing the two single quotes with the word None. After this
change, if I printed the value of boffile after the "if" statement,
I got the expected behavior: the default of tut2.bof when I invoked
the script without the -b option and whatever I entered when I
invoked the script with the -b option.

Another option would be to comment-out the "try" catch in the
script and rerun it to see what the exception is. For some reason,
the correlator fpga object's never being initialised and so the
logging's not even working. You want the traceback to figure out
where it broke.
