Hi Armando,
I used the same solution as you, and the OPB2WB wrapper works.
But now there is one other problem. The wrapper works only if I try to
write to the 0x80000000 address. If I change the address range of the
OPB2WB wrapper in EDK to in example 0x80018000, the OPB2WB does not
work, I mean it does not assert CYC and STB signals. I tryed to change
the PARAMETER C_BASEADDR=32'h8000_0000 C_HIGHADDR=0x800000ff to    
C_BASEADDR=0x80018000 C_HIGHADDR=0x800180ff, but it does not work.
It works always only if I write to 0x80000000.
This is a problem because if I use 2 WB cores, it means that I need 2
wrappers in EDK, but they must have different address ranges,
otherwise all data will be sent to both cores. But the wrappers works
only in  the same address range 0x80000000 -> 0x800000ff .
I hope I was clear in my explanation.
Thanks for any suggestion.
Regards 

Sami (secamiei)
