    Subject: [pci] WB Slave Unit doesn't reply
    Top

    Hi!
    
    I can't obtain any reply from the core WB slave unit in guest
    implementation.
    
    I connected a WB master unit to the WB bus. When my master unit puts
    right (I suppose :-) ) address and data on the WB bus and asserts its 
    stb_o and cyc_o and we_o to write a data to the slave unit, I can't see 
    any assertion of slave ack_o, rty_o or err_o line.
    
    I've set the 31th bit of the wb_am1 register. Is there some other bit or
    flag to set in the configuration space?
    
    Thank's a lot.
