Can you try'n do a "fpga.listdev()" after programming? I'm wondering if the
FPGA is perhaps actually not being programmed at all (which could be for a
number of reasons, usually permissions related). If so, you'd get an error when
trying to list the devices on the board.

This really should have worked. Check to see if your logger object was
instantiated correctly.

Apparently your fpga.read_int failed to execute and then it couldn't log the
error to a non-existant logger (which you removed with your one-line change
above).

Suspect versioning problems between the text and the actual model files and
python scripts. AFAICT, the "-s" option is now always present.

You might want to try'n execute the lines in the script one-at-a-time on a
python prompt to see what errors popup at what stage.
