          When I build USBtoI2S code,display error:Routing of asynchrononus signal Clock_1 as a clock to UDB component "\AudioClkGen:UDB_ACG:div:Div:u0\" is not supported unless a UDB Clock/Enable component is use

             

          Base on above question,How to solve it?

              Hello David,

                 

              The clock that goes in to any of the UDB based component in PSoC3 could be of synchronous or asynchronous nature(synchronous to the BUS Clock). It is necessary to have the clock input to the I2S component synchronous. To achieve this,

                 
                    
              • you need to place a "UDB Clock Enable" component on your Topdesign
              •     
              • Connect the input clock to the input of the UDB Clock enable component
              •     
              • Set to "true"
              •    
                 

              This should fix the issue. If you are still not able to resolve the issue please raise a case so that we can track and fix it.
