Implementing onchip dual access ram

[Altera_Forum]

Hi, 

 I am trying to implement an onchip memory as a framebuffer. Although I like to do some image improvement using vhdl code.  My problem is, when I add the support for dual access ram in the SOPC Builder, i get an error that both slaves have the same adress range, as it should be.  So could you give me a hint, where I am wrong?  Thanks a lot for your help  Best wishes

Are both slaves connected to the same master? In that case you'll have this error. The fabric can't know what slave to connect to.

No, one is connected to the CPU Data and Instruction master, the other one is connected to the "External Bus to Avalon Bridge".
