【问题描述】:
我想将以太网帧从 FPGA 发送到我的 PC 以供 Wireshark 接收
我将有效负载传递给 CRC 生成器以获取 CRC 结果,但我猜是 CRC 错误,因为 wireshark 没有收到任何我的有效负载
我有 2 个想法
1. find a ethernet frame in hex code in internet and copy to VHDL to send in order to make sure no CRC error and check whether it send or not? could you post a correct ethernet frame in hex code here?
1b. any free CRC generator code in VHDL available in internet? and any free CRC generator code in C++ language or C# language or Java language for hard code CRC in ethernet frame?
2. use layer 2 programming in ubuntu to send a ethernet frame to another computer,
whether i can send and display the ethernet frame which i send in ubuntu or i need to capture with wireshark in another computer?

如果您只需要一个以太网框架,为什么不使用 Wireshark 捕获您浏览本网站的数据包?

这个问题的答案可能会有所帮助,虽然我不认为它是重复的:stackoverflow.com/questions/12497608/…
