I have integrated FreeRTOS and FReeRTOS-IP.
I’ve created a task that implements a TCP echo server.
I have a TCP client that sends a string to the TCP echo server written in Python, which I know it’s working with a LwIP TCP echo server.
The Nucleo-144 is programmed with an IP address of 192.168.0.10 (mac address 0x00, 0x11, 0x22, 0x33, 0x44, 0x55) and the Windows machine is 192.168.0.100.
I’m using port 80.
I can see with wireShark that the ARP is sent:
11 61.282383 Dell_43:e4:58 Broadcast ARP 42 Who has 192.168.0.10? Tell 192.168.0.100
But no answer is coming back.
Any ideas on how to find out what is going on?
