Avalon MM slave/master to AXI Stream Master/Slave

[nt261]

Hi I'm unable to connect Avalon MM slave/master to AXI Stream Master.  I'm getting error messages as attached.

1)Do we need to connect any bridge in between?

2)how to connect Avalon MM slave/master to AXI Stream Master/Slave

3)Axi slave/master to AXI Stream Master/Slave

(Host = master, agent = slave)

Avalon memory-mapped interfaces cannot be bridged to AXI streaming interfaces (assuming we're talking about connections in Platform Designer) or vice versa.  Avalon and AXI memory-mapped interfaces can be connected to each other, but the streaming versions cannot (and you can't connect Avalon streaming to AXI streaming either).

How can we connect AXI/AXI4 slave/master to AXI Stream Master/Slave in Platform designer?

As I said, you can't.

Sstell was right, if you want to do that, you will have to write your own custom bridge for that.

We do have example for avalon but not for axi
