Rgmii debug. 3所示。 2. Lan7430 runs now in different speeds, also ‚hot swap‘ between different speeds works well. 9 Debug the MAC Interface RGMII The RGMII signals are summarized in Table 2-10. Note This Debug application note mainly focuses on RGMII and SGMII interface debug Jun 15, 2022 · Hardware issues can range from link bring-up to problems seen after hours of testing. iddr 接收用iddr（xilinx的平台）接收数据。 iddr：输入双数据速率寄存器。专门来采集双沿数据。 主要有三个模式，详情可以参考 ug471_7Series_SelectIO这个文档。 我用的是SAME_EDGE_PIPELINED这个模式，这个模式下数据的高位和地位会出现在时钟的上升沿上。这些就不用打拍拼数据了。 Debugging Tips The following sections are separated based on the different Ethernet modes of the GEM configurations. It is achieved by setting the pull-up and pull-down resistance of IO. DP83867IR: This film supports MII, GMII, RGMII, and the second function included in almost all of the rx_data signals. 3所示。 Jul 28, 2024 · RGMII接口中的双沿数据信号适于传输，但并不适于数据处理，因此在MAC核内处理PHY侧数据时首先需要将双沿数据变换为单沿数据。 在Crossbar交换机实现时硬件平台采用的是RGMII接口，故需要实现RGMII接口与GMII接口的相互转换，如图4. Aug 24, 2025 · In i. Perform these steps after the DUT has successfully booted into a Linux environment. Apr 29, 2022 · 对于Altera（现在叫Intel）的FPGA，也可以采用SignalTAP里面的探针来动态的配置接口时延，来实现动态的调整RGMII接口数据与时钟相差四分之一相位的目的。 不过，根据本人的经验，Xilinx的FPGA实现RGMII接口时序调整要比Altera的FPGA容易太多了。 。。 文章浏览阅读4k次，点赞53次，收藏25次。硬件工程师检查原理图和PCB，核查RGMII线路连接是否正确，PHY的 TX连接对端 RX，PHY的RX连接对端TX，原理图上以引脚序号+引脚名+ 引脚类型 (输入还是输出)逐一核查RGMII接口各个网络，确保接口两侧均为收发对接；确认RGMII接口两侧芯片都已工作在RGMII模式，且 Aug 27, 2020 · RGMII接口中的双沿数据信号适于传输，但并不适于数据处理，因此在MAC核内处理PHY侧数据时首先需要将双沿数据变换为单沿数据。 在Crossbar交换机实现时硬件平台采用的是RGMII接口，故需要实现RGMII接口与GMII接口的相互转换，如图4. . Jun 15, 2022 · Many tools are available to address GMII to RGMII design issues. 206; ③ Carrier board: A user - self - made carrier board. The Vivado debug feature is a valuable resource to use in hardware debug. It listed four cases in attached. TX_CLK TX_CTRL TX_D[3:0] Dec 6, 2025 · 最近一段时间都在调试上述这四种接口的网络接口，使用的是 FPGA （microblaze+ethernet），移植xilinx官方的xapp1026的方案，使用了两款PHY芯片，DP83867IR (MII GMII RGMII)和KSZ8091RNB (RMII),现在功能全部都已经调通了，现在将最近三周的收获做一个简单的总结： 监于两块芯片的官方均已经提供了demo板，现在只把 Apr 3, 2013 · For details about MII (100Mbps), SGMII (1Gbps, serial), RGMII (1Gbps, reduced) definition, you can google them. Normal mode and fixed-phy mode coexist properly. Figure 1-1. This article describe RMII HW design and SW config. Thanks, I found the cause, the delta patch is submitted. The signal names mentioned in the following individual sections can be probed using the debug feature for d Debugging Tips The following sections are separated based on the different Ethernet modes of the GEM configurations. Some customer use RMII connection. This section provides debug steps for common issues. It is important to know which tools are useful for debugging various situations. RGMII (MIO) and GMII (EMIO) ZCU102 GEM3 is hard-wired with an on-board TI PHY. This article provides a clear and efficient debugging solution. Basically speaking, NIC (Network Interface Card) consist of one MAC block and related PHY chip, and other peripheral modules. The connection to the media is via a transformer and a connector. MX93 EVK, it use RGMII in ethernet connection. The following is a summary of the first steps in debugging the Ethernet interface. Note This Debug application note mainly focuses on RGMII and SGMII interface debug Figure 1-1. The following sections approach the debug from a high level, attempting to start with application characteristics that have a broad impact and then zeroing in on more focused aspects of the design. DP83867 Block Diagram The DP83867 can connect to an Ethernet MAC and to a media. 1. May 27, 2009 · I was playing around with my FPGA design constraints file such that I was shifting all the non clock RGMII signals to get the required oversall shift relative to the clock. 某phy的rgmii接口 2. Such problems can be resolved through three simple steps. Test Conditions ① Hardware: Forlinx RK3568 SoM; ② System: Linux 4. The SDK LWIP echo application can be used directly out of the box to test this interface. 19. And also one Ethernet device driver should work with the NIC hardware. vtk ini jys qir kwg qbk ntf pwc hjj ehs jbt rcn tas iua wxc
