Need example using OpenCores MAC on DE2-115

Hi, all,

I am trying to use Avalon OpenCores 10/100 Ethernet MAC developed by jakobjones on a DE2-115 board but no success.

I followed the document of jakobjones to connect the MAC in Qsys and tried to run a simple socket server in Nios II IDE with ETH_OCM_PHY_SUPPORT_MVL88E1111 symbol defined. But I met two problem getting the example running successfully.

1. The Nios II project generated by Nios II IDE contains a tse_my_system.c file, which includes tse driver files that don't exist in the BSP.

2. If I exclude that tse_my_system.c file from Nios II build, I could get the simple socket server to run but I keep getting DHCP timeout. I also tried static IP but still no luck.

Could anyone kindly help me by showing me a working design example of OpenCores MAC on DE2-115 board?

Thank you in advance for your help.
