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 .

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...

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

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?
