Download Rev2 Update

To get the Rev2 update with the resolved issues described above, apply the following patch to the Xilinx ISE 13.1/13.2/13.3 software installation:

http://www.xilinx.com/txpatches/pub/swhelp/ise13_updates/ar40624_tri_mode_eth_mac_v5_1_rev2.zip

Install the patch by extracting the contents of the ".zip" archive to the root directory of the Xilinx ISE 13.1 software installation. Select the option that allows the extractor to overwrite all of the existing files and maintain the directory structure predefined in the archive.

After installing the patch, regenerate the LogiCORE IP Tri-Mode Ethernet MAC v5.1 in the 13.1 CORE Generator tool. For further information on finding the Xilinx installation and using environment variables, see (Xilinx Answer 11630).

Note: You might need system administrator privileges to install the patch if you do not have write permissions to the Xilinx installation directory.

Rev1 Update Download Link

http://www.xilinx.com/txpatches/pub/swhelp/ise13_updates/ar40624_tri_mode_eth_mac_v5_1_rev1.zip

Note: Fixes in Rev1 Update are also included in the Rev2 Update. Therefore, the Rev1 Update installation is not required if the Rev2 Update is installed.
