ZynqMP的GEM (gigabit Ethernet controller)的框图如下,可以通过PCS连接到PS-GTR,转为SGMII;或者通过GMII to RGMII Adapter转为RGMII 通过MIO接出;或者通过EMIO将GMII接入到FPGA当中。 XX设备是通过第一种方式,用GTR实现了SGMII接口,然后将其直接连接到了连接器上,这样就需要我在PL实现SGMII接口与其直接对接。 IP核...

SFP 接口的 FPGA 开发板可以通过安装 SFP 转 RJ45 模块或者直接通过光纤进行以太网通信。上层协议就是用户实际收发的有效数据部分,而“TriMode Ethernet MAC”IP 核负责处理以太网的 MAC,以及通过 GMII 接口和“1G/2.5GEthernet PCS/PMAor SGMII”IP 的接口 GMII 接口通
4. AXI Ethernet默认不支持fixed-link模式,加载驱动的时候报错Connection timed out,跟踪发现是axienet_open函数里有访问MDIO的函数调用返回失败,手动屏蔽MDIO的访问函数后重新编译加载驱动没有出现再报错的情况:

uiudp_stack是一个“黑盒子”负责处理 ARP 以及 UDP IP 通信协议,上层协议是用户实际收发的有效数据部分,“10GEthernet SubsystemIP"核负责处理以太网数据通过GTX高速串行接口传输。
I have a board with a Zynq-7020. The FPGA connects to an external Ethernet PHY using the Enet0 interface of the MIO (MIO[27:16] and MIO[53:52] for the MDIO). The Ethernet reset; however; is connected to pin T9 of the FPGA; which is a PL GPIO pin.<p>...
