大家好,我将不胜感激如果有人可以help me solve this strange problem regarding Ethernet transmission of UDP packets in RAW mode with LwIP from Zedboard to Windows PC. I’m using the example project in SDK to test the functionalities of LwIP called udp_perf_client. If I try to use the project as it is (with UDP_SEND_BUFSIZE 1440 ) Whireskark signals that packet are malformed , in fact it seems that “data bytes” are being truncated so are sent less bytes than expected (declared in the costruction of the IP header by LwIP). In the image attached is shown the case of UDP_SEND_BUFFSIZE of 600 bytes for example. Packets arrive successfully only if the size of the Ethernet frame is smaller than 500 bytes. I tried to modify the LwIP options in Board Support Package without success. I can’t address the problem . Thanks in advance

Hi. I have a problem while trying lwIP Echo server wiht Zybo-Z7 I follow this tutorial faithfully https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-getting-started-with-zynq-server/start but I face with a problem This problem occurs for both connection through router and connection directly with my laptop or desktop I try with 3 PC and all of it shows same result. Google suggest me to configure ethernet to be 100Mbps half duplex with Fixed IP settings and it doesn't work. I double-check that I'm using correct MIO pin and fix the 100Mbps at SDK. Is there any solution to resolve this problem? Thank you.

嗨，我想利用SDK来测试Echo Server LWIP，FPGA程序和运行式的元素。但是，在控制台中，有些行让我感到困惑。----- LWIP TCP回声服务器------发送到端口6001的TCP数据包将回动回链接速度：1000 DHCP超时配置192.168.1.1.10董事会IP：192.168.1.1.1.10 NetMask：255.255.255.0 Gateway Gateway：192.168.1.1 TCP回声服务器在PC上播放板时启动 @端口7，它显示“无法访问目标主机”我的板子是Zybo。硬件是在Vivado 2014.3.1中构建的Zynq7 System Processing Core什么是错误的？问候，索菲亚

因此，我有Artyz7-20，我想使用LWIP库通过以太网发送数据到另一个板（ZC706）。我该怎么做？我已经成功地测试了两个板上的“回声服务器”示例。有人可以指导我朝正确的方向引导吗？任何帮助都将受到赞赏。

Hello I have a microblaze running a LwIP server adapted from the lwIP server example where everything works fine. LwIP stops working when I use another peripheral with an interrupt attached to it. In my case I have an SPI EEprom running perfectly, but after initialization LwIP stops working. The EEprom code is also standard code from the example. Interrupts are all connected to the microblaze with a concat IP. Has anybody experience in this topic?

我已经实现了一个使用Zybo-Z7 20的小型系统，它将通过以太网接口发送开关状态。通过AXI GPIO和LWIP实施，Unicast具有恒定的IP，并且远程IP是恒定的。我不使用DNS，如果将板直接连接到笔记本电脑，我可以发送数据包，并且我能够从笔记本电脑上使用木板，但是当连接到Switch [Allied Teleasis]时相同的设置时，我无法ping the Board，否数据包在流动...任何人都可以帮助我，我必须看...

Hello, I am working on the Zybo-Z7-10 development board, I want to establish a web server application to upload files from my PC and send it to web browser by HTTP POST and extract data inside the file, I am using the lwIP stack and downloaded the xapp1026 files from the gitHub, right now I can run the example application correctly, but I want to change the content inside the image.mfs file provided by the xilinx, I cannot open it, once I open the image.mfs by NotePad, unreadable characters are displayed, I found that at the top of this file, there is a css part, on the bottom of this file I can recognize that there is a html part, so I have modified it by adding a part of , however it is vulnerable to errors, besides, i still need to write the js functions for getting the file. Do you know how can I create my own web browser and do not use the image.mfs file? Actually, I tried the mfsgen -cvbf command too, but I cannot change anything inside the file! can you help me on this problem or provide me with some references for the same question? Thanks a lot!

您好，我正在运行Vivado 18.1，并想尝试通过关注此演示来使Echo服务器运行。我了解该演示尚未在Vivado 18.1上进行验证，但是我想尝试一下。唯一的问题是，即使我对创建它的步骤进行了仔细检查，我的框图与演示屏幕屏幕镜头上显示的内容不完全匹配。是否有一个BD TCL文件可用于为演示重新创建此图。如果没有，可以发布完整图的更高分辨率图片吗？
