This error message occurs when building an example design using the Scatter-Gather DMA Controller Core with Simple Socket Server using the Nios® II Software Build Tool in Quartus® Prime Standard Edition ver.17.1 or later.

Starting with version 17.1 of the Nios® II Software Build Tool sample code Simple Socket Server, the controlled DMA controller has been changed to the Modular Scatter-Gather DMA Core.
(Before ver.17.0, the Scatter-Gather DMA Controller Core was controlled.)

You can avoid the error by removing the Scatter-Gather DMA Controller Core from the example design and adding a new Modular Scatter-Gather DMA Core.
