1、硬上件原理部分如上设计,确认在29脚浮空,24脚高亮驱动LED的情况下,电口完全正常,包括LINK UP ,LINK DOWN,LED状态等。 --- 光口模式下 1、当配置为光纤模式时,断开电口信号,通过0.1UF电容与1X9光模块连接。(光模块部分功能正常,已确认) 2、29脚通过上下拉电阻配置为光纤使能,24脚 断开LED后上拉...
建立任务监控网口硬件连接状态(link up/link down)。 图244 图245 如需设置为静态IP地址,可参考如下说明。 修改宏定义,1表示自动获取IP地址,0表示使用静态IP地址。 图246 设置静态IP地址、网关和子网掩码。 图247 Vivado工程说明 通过GMII to RGMII IP核,将PS端的千兆以太网控制器(GEM1)的GMII接口转换为RGMII...
