I have the same probleme than you. I can't write in the register .

Hi Mark,
Are you willing to share the wrapper?
I can add it to the tarball.
More people are asking for this ...

Thanks,
Richard

I recently sucessfully integrated the I2C core onto an Avalon bus in a 
Cyclone II without any problems whatsoever.

I used a top-level wrapper to convert the unsigned wb_adr_i to 
std_logic_vector and also remove the std_logic generic ARST_LVL (SOPC 
Builder barfs on std_logic parameters).

I guess the only difference here is that I'm not actually talking to it 
from the NIOS, but rather from another micro which interfaces to the 
Avalon bus externally.

But I can confirm that it does indeed work.

Regards,
