LogiCORE Tri-Mode Ethernet MAC, 10-Gigabit Ethernet MAC, AXI Ethernet and AXI 10G Ethernet - Vivado 2014.4 and earlier - AXI lite interface failures seen when using 64-bit master

Description

When using the following cores in in Vivado 2014.4 and earlier:

  • LogiCORE Tri-Mode Ethernet MAC
  • 10-Gigabit Ethernet MAC
  • AXI Ethernet
  • AXI 10G Ethernet

If a 64-bit AXI-Lite master is used for multiple read requests the Ethernet core AXI-Lite interface could fail to respond and hang.

Solution

This is planned to be addressed in the 2015.1 release and can be worked around by using the 32-bit AXI-Lite Master.
