I am sorry, I think I didn’t get yet this matter. Do you know some sort of methods in order to communicate with fast throughput between 2 Teensys, so that is worth using 2 to “create/simulate” a single platform which receives packets and process...

Yes, for w5500 I use MACRAW mode with socket 0 in order to be able to access raw frames.

If I remember correctly, SPI rate was around 45-55 Mhz, while I used ioLibrary to talk to the w5500, and also used spi burst read and write functions. I understand your suggestion, but I would like make it work like a standalone device, to be...

Well, I tested the both interfaces with a PC host and native managed to achieve 90mbps while w5500 around 30mbps. What do you suggest with 2 Teensy boards and what you refer by “some fast interface”?

Well, I have a university project where I want to achieve something similar with a packet sniffer / proxy etc. For the moment I have a setup with 2 PCs and the teensy between them. The goal is to filter the packets which go to one of the PCs. So...

Yes, I managed to do that by accessing raw frames.

Thank you a lot for addressing that. I tested and I can confirm that it works. But now I have encountered another issue. I am trying to capture packets on W5500 interface and process and then send them on the native interface and vice-versa. The...

I finally fixed the ping issue. I wasn't calculating the ICMP checksum in some cases.

Thank you for your response! Well, I looked on the code you provided and it seems to be helpful. I do not develop a new library for ethernet communication, I just look for a method to receive frames and to modify them, but preserving ARP and...

So you suggest to try setting LWIP_IPV4 to 0, and then keep only #if LWIP_ARP in src/netif/ethernet.c? Sorry for being late with the response, somehow I was not notified…

Hello everyone, I am using Teensy 4.1 development board with the native ethernet chip and an external Wiznet W5500 ethernet chip. As the W5500 chip is concerned, I figured out that the ioLibrary allows me to access RAW ethernet frames so that...
