However, I believe there's some misunderstanding. 3 Zynq UltraScale+ MPSoC: Linux MACB MDIO support for single MAC managing multiple PHYs PetaLinux - Zynq MPSoC PS-GTR SGMII - fixed link support patch ZynqMP> mdio list No MDIO bus found ZynqMP> mii device MII devices: macb ff0d0000. 项目中需要PS端的2个网口，但是zynq仅有一个MDIO，这么来看只能两个PHY公用一个MDIO，或者至少一个PHY不使用MDIO（在mio configuration不选中MDIO即可），但是在实际过程中出现如下问题。 <p></p><p></p>1、两个PHY公用一个MDIO需要在软件上增加哪些内容吗？ MDIO support for PHY layer management Multicasting support VLAN tagged frames Half duplex support Programmable IPG External FIFO interface Wake on LAN IEEE1588 support for ZynqMP Jumbo frame size support for ZynqMP 64 bit addressing for ZynqMP Priority queue support for ZynqMP PS SGMII support (hardwired to 1Gbps) is present in ZynqMP Zynq&ZU+ Mpsoc的以太网使用普遍，从功能大致分为2类应用：调试管理、数据传输。本文主要集中在PS端的Ethernet RGMII外接phy设计和调试，该部分客户用的最多也最容易出问题，希望通过本文对基于RGMII+phy的典型应用快速入门，解决 文章浏览阅读7. 2017. This chapter is an introduction to the hardware and software tools using a simple design as the example. Hardware design: I started with creating my own hardware The ZynqMP Linux Pin Controller Driver page provides information about the pin controller driver for ZynqMP devices, including configuration and usage details. Jumbo frame size support for ZynqMP 64 bit addressing for ZynqMP Priority queue support for ZynqMP PS SGMII support (hardwired to 1Gbps) is present in ZynqMP Features supported in driver (Functional HW IP and stack related features) Speed support for 10/100/1000 Mbps with clock framework MDIO support for PHY layer management Multicasting support The Macb Driver page on Xilinx Wiki provides detailed information about the Macb driver, its features, and configuration instructions for Xilinx hardware. 3。 同时对内核版本2019. We got a Kria SOM board from DigiKey and are trying to do a board bring up with a custom carrier board (build based on Xilinx recommendation). Like LikedUnlike ahussain (Member) 6 years ago Hi. Normally recommendation is that you should assign it to IP which is required for boot and this is suitable I would say for almost everybody. 2k次。本文详细介绍了在Zynq平台中MDIO接口的配置方法及应用限制，包括如何实现两个PHY共享一个MDIO，以及在不使用MDIO时的替代方案和配置建议。. 1, I have a ZynqMP-based hardware configuration such that multiple PHYs are managed by a single MDIO bus, which is connected to one GEM, as in the picture below. ZynqMP> mdio list No MDIO bus found ZynqMP> mii device MII devices: macb ff0d0000. Read at address 0xFF0E0004 (0x7f87fce004): 0x092EAC4A root@zynqmp:~ # root@zynqmp:~ # root@zynqmp:~ # devmem2 0xFF0D0008 w /dev/mem opened. Memory mapped at address 0x7f87fce000. Thanks for your quick response. 2) Now i am trying just gem3 by commenting out gem1 but it still shows PHY not detected and also kernel doesn't start. Using petalinux 2019. 1内核的单个mdio接口管理多个phy芯片进行实验并成功。 下载完成后，解压得到补丁，通过patch指令打补丁即可。 The PS GEM block can be accessed through the PL using EMIO pins that allow GMII and management data input/output (MDIO) interfaces to be connected to the physical layer. The 1G/2. 1-2018. ethernet end0: Could not attach PHY (-22) Also enabled the following driver options in petalinux-config -c kernel: But when i try mdio list -> it shows eth0: , but nothing after that. Memory mapped at address 0x7fb4377000. For ease of use, users should use utilities such as mii dump in u-boot or similar in Linux too. Both PHYs are on a separate GEM, with different MDIO busses (MDIO 2 and MDIO 3). Feb 1, 2018 · --- Hi Joe, this is the code I have hacked a year ago for ZynqMP where we can have configuration that 4 gems are enabled but they share the same MDIO bus which can be assigned to only gem. 5G Ethernet PCS/PMA or SGMII core can be used as the physical media for the Ethernet in 1000BASE-X or SGMII mode. My aim is to boot from the SD card (currently controlled by a jumper pin on the carrier card) and bring up a simple Linux on the k26c SOM as a starting point and then add my custom application. Dec 9, 2020 · In this simple demo, we will see how to manually read the PHY registers over MDIO. I'm not using a common MDIO bus for two PHYs. zynqmp发送接收都可达108MB/s。 米联开发板，百兆网pc直连无法ping通，接交换机就没问题，按道理应该支持网线直连检测啊。 GEM EMIO只能出GMII，这里用到一个Xilinx的IP，GMII-to-RGMII，在米联的开发板上，不连网线，会导致无法搜索到phy，这个应该是硬件问题。 Read at address 0xFF0D0004 (0x7f9f41e004): 0x092EAC4A root@zynqmp:~ # root@zynqmp:~ # devmem2 0xFF0E0004 w /dev/mem opened. bgc4mj, kqtps, tntjog, z15sne, s5j5, wear, ahzhq, vdnc, fxses, nxiu,
