Qsys: Warning: No matching role found - Qsys: Warning: No matching role found Description Qsys does not support the following Avalon Memory-Mapped (Avalon-MM) flow control signals: dataavailable , readyfordata , endofpacket , and flush .For components that use the deprecated Memory-Mapped flow control, Qsys issues warnings during generation. For the Altera Avalon JTAG UART and DMA Controller components, Qsys generates messages similar to the following: Warning: "No matching role found for jtag_uart_0:avalon_jtag_slave:dataavailable (dataavailable)" Warning: "No matching role found for dma_0:read_master:read_flush (flush)" Resolution You may safely ignore these messages for Altera components because the signals are not required for design operation.If generation of a Qsys system produces similar messages for a custom component or IP block, check with the custom component or IP block author to ensure that the signals listed are not required.
