Ok, so I updated the libraries and I'm having the same problem, however
I notice that now I have two new registers: 'ddr3_ctrl', 'ddr3_mem'. I
suppose those are the registers that I'm missing changed names. There
was a name changing in the library so that it make incompatible with the
katcp_wrapper script?
thanks,
Franco

No, I'm using the tutorial version. That might be the problem. However
I'm reluctant to update since this might cause incompatibilities with
my previous models. I suppose that if I what to use the DRAM I don't
have other choice. Do you have any suggestions?
Many thanks,
Franco

Are you running the latest version of the toolflow? Earlier versions
did not include the CPU interface to the DRAM.
