12.1 EDK - "EDK:2159 - Point-2-point interface connector 'hard_ethernet_mac_llink0' must have only 2 connection points"


A systemconfigured with theXPS_LL_TEMAC instance generates the following error during implementation:

EDK:2159 - Point-2-point interface connector 'hard_ethernet_mac_llink0' must have only 2 connection points:
EDK:1420 - For point-2-point interface connector 'hard_ethernet_mac_llink0', the BUS_TYPE value of the connection points must have a TARGET and an INITIATOR:
EDK:440 - platgen failed with errors!

How can I resolve this issue?


Theerror occurs because the LocalLink interface inthe XPS_LL_TEMAC coreis left unconnected.

The Ethernet frame data to be transmitted and the frame data that is received passes between the XPS_LL_TEMAC and the rest of the embedded system via Xilinx LocalLink interfaces. The other end ofthe LocalLinkinterface can be connected toa DMA controller,XPS Local Link FIFO, or any custom logicas long as it meets the requirements of the XPS_LL_TEMAC LocalLink interface.

For more details on this interface, refer to the XPS_LL_TEMAC Data Sheet: http://www.xilinx.com/support/documentation/ip_documentation/xps_ll_temac.pdf
