After adding a mii_to_rmii core to an XPS project, and making the connections between xps_ethernetlite and the mii_to_rmii core, the following platgen error occurs:
ERROR:EDK - xget_value name : a null handle was provided ERROR:EDK - Ethernet_MAC (xps_ethernetlite) - expected integer but got ""
How do I resolve this error?
解决方案
This problem is caused by irrelevant OFFSET IN/OUT constraints generated by the XPS_ETHERNETLITE TCL file, which assumes that the PHY signals will be connected to external I/O pins.
