For components using deprecated Memory-Mapped flow control, Qsys (Beta) issues warnings during generation

Description

For components that use the deprecated Memory-Mapped flow control, Qsys issues warnings during generation. For the Altera Avalon JTAG UART component, Qsys generates the following messages:

Warning: “No matching role found for jtag_uart_0:avalon_jtag_slave:dataavailable (dataavailable)”

Warning: “No matching role found for jtag_uart_0:avalon_jtag_slave:readyfordata (readyfordata)”

For the DMA Controller component, Qsys generates the following messages:

Warning: “No matching role found for dma_0:write_master:write_endofpacket (endofpacket)”

Warning: “No matching role found for dma_0:read_master:read_endofpacket (endofpacket)”

Warning: “No matching role found for dma_0:read_master:read_flush (flush)”

Warning: “No matching role found for dma_0:control_port_slave:dma_ctl_readyfordata(readyfordata)”.

Resolution

You may safely ignore these messages because the signals are not required for design operation.
