Ethernet tool to analysis

[Ash1]

Hi 

I am trying to communicate via ethernet on STm32f407 board with phy LAN8720. I have used TCP protocol and I have used Hercules for sending and reciving frame. But I want to acheive the operation sung HAL_ETH_Transmit (I want to send raw ethernet frame ).

note: Can you suggest me any tool I can use to analysis Ethernet frame (send and recv.) tool like USB CAN analyzer for CAN .

As I said in your earlier thread, Wireshark is the de facto standard ...

https://www.wireshark.org/

 

Nothing specific to STM32.

hi Andrew 

Can you tell me how I can send a frame via wireshark to my board.

Note1: I have achieved sending and reception via hercules, But now I want to achieve with raw frame using HAL library directly instead of TCP/UDP protocols and I can see frame on tool and can send frame from tool this was my query (I have tried Wireshark but I am unable to understand how I can send frame to my board ) I hope you got my point?

Note2: Is it possible whatever I asked you above or using TCP/UDP any protocol is mandatory?

To my knowledge Wireshark is not intended to send ETH frames but to sniff and scan the network.

You can use Hercule to send and receive TCP or UDP packets.

Have you looked at LWIP_HOOK_UNKNOWN_ETH_PROTOCOL: at https://www.nongnu.org/lwip/2_1_x/group__lwip__opts__hooks.html#ga6cc92f5101dd7a0420e18e1f2101abf4

You might get some ideas from the rest of that thread...
