阅读《xapp1082 - PS and PL Ethernet Performance and Jumbo Frame Support with PL Ethernet.pdf》,在Introduction一节可知,ZYNQ芯片支持三个网口: PS-GEM0:PS侧内置MAC,通过RGMII接口连接到外部PHY芯片。不支持Jumbo Frame。见下图紫线。 PS-GEM1:PS侧内置MAC,通过EMIO接口连接PL侧的PHY(1000BASE-X或SGMII)。...
$ cd images/linux/; petalinux-package --boot --fsbl zynq_fsbl.elf --fpga system.bit --u-boot --force 然后将生成的BOOT.BIN和image.ub拷贝到SD卡根目录下,将SD卡插入板子上,上电运行。 (6) 功能验证 上电后,看到内核里的如下启动信息,说明GEM0和GEM1都已经枚举成功了: image.png 在Linux shell...

使用iperf对zynq进行单socket tcp传输速率测试; 无网络损伤时,单向网络带宽约为600Mbps,双向网络带宽相加约400Mbps; 50ms延时,1ms抖动,无丢包时,单向网络带宽约为155Mbps,双向网络带宽相加约40Mbps; 和内核版本无关,经技术支持确定为PS GEM DMA的双向传输存在缺陷。
73065 - Zynq-7000 PS GEM Bidirectional Performance Description This answer record summarizes the bi-directional performance of the PS GEM on the Zynq-7000 device. The measurements are obtained on an Ubuntu 16.04 LTS high-performance host machine. Performance is expected to differ when a diff...
本主答复记录列出了 MPSoC 器件 PS 中千兆位以太网 MAC (GEM) 控制器的所有已知问题。 Solution 概述 在Zynq MPSOC 器件上,我们在 PS 中提供了 4 个 GEM,GEM 可为以太网通信节省 PL 资源,因此日益受到客户的欢迎和采用。 我们针对该硬 IP 提供了 MACB Linux 驱动程序和 EMACPS 独立驱动程序。
The “compatible” string "cdns,zynqmp-gem" is for ZynqMP. This compatible string enables the use of jumbo frame sizes, 1588, and hardware timestamping support, as well as any features exclusive to ZynqMP. For the “phy-mode” string, users can refer to the following page: ...
