您好，AXI 1G/2.5G Ethernet Subsystem不能使用

您好，我在学习网站中（高级篇）S05-CH03 Microblaze LWIP TCP 方案的例程，最后不能生成bit流文件，希望能得到帮助。谢谢
提示错误如下：
[Common 17-69] Command failed: This design contains one or more cells for which bitstream generation is not permitted:
DJ_i/axi_ethernet_0/inst/eth_mac/inst/tri_mode_ethernet_mac_i/bd_fe4a_eth_mac_0_core (bd_fe4a_eth_mac_0_tri_mode_ethernet_mac_v9_0_6)
