Hi Claudio, cc. maillist
Have you modified the tut3 software or firmware? You seem to have a problem
reading the "even" bram. Does this exist in your model? Are you reading the
correct number of bytes from it -- the error message suggests you tried to
read 4096 bytes -- is this right?
Can you talk to the board interactively (eg, in an ipython shell)? Does it
appear to program ok?
Cheers
Jack
