SDK 2014.2 - LwIP echo server does not work on systems with AXI Ethernetlite


The LwIP echo server application available in SDK examples fails on systems with AXI EthernetLite IP. 


The issue was determined to be with the Ethernet Lite interrupt setup in LwIP.

The updated Tcl attached to this answer record resolves this issue.

This issue will be fixed in SDK 2014.3. 

To use this Tcl -

1. Create a custom repository and copy the library lwip140_v2_1 from the install area to this location. 
2. Replace the file, lwip140_v2_0\data\lwip140.tcl with the attached file.
3. Map the repository to SDK workspace and recompile the application.

Refer to (Xilinx Answer 35443) for information on creating custom repositories.
