Hi Istvan,

when you say you are using the block diagram editor, does that mean you are using the Megawizard to generate the IP cores? What is the parameter set that you are using for the Scaler II?

Also, when you say that you are using the 'new type of Avalon MM interface', does this mean that you have just changed the register map to match the Scaler II, or are you trying to use the dynamic addressing described in previous posts? Whether the slave uses dynamic or native addressing is only relevant if you connect IP cores using SOPC Builder. If you use the schematic flow to connect blocks then the slave will effectively always use native addressing.

Best regards,

Kieron
