[求助] virtex -5 m507用ISE 14.7 添加GPIO模块时的问题

最近在学习EDK开发时，在添加GPIO模块，当然我没有添加DDR2的IP核，然后生成网表时出现了下面的问题，不过bitstream生成成功： Assigned Driver intc 2.02.a for instance axi_intc_0 axi_intc_0 has been added to the project ERROR:EDK:4125 - IPNAME: xps_gpio, INSTANCE: xps_gpio_0, PARAMETER: C_BASEADDR - ASSIGNMENT=REQUIRE is defined in the MPD. You must specify a value in the MHS. ERROR:EDK:4125 - IPNAME: xps_gpio, INSTANCE: xps_gpio_0, PARAMETER: C_HIGHADDR - ASSIGNMENT=REQUIRE is defined in the MPD. You must specify a value in the MHS. WARNING:EDK:2137 - Peripheral axi_intc_0 is not accessible from any processor in the system. Check Bus Interface connections and address parameters. 然后进入到SDK中进行设计时，板级支持包添加没问题。 怎么消除这个error啊？ 各位大能，帮帮忙
