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