I am using LWIP 2.1.2 in stm32f769I discovery board.
I can ping IPv4 from my PC.
But i can't ping IPv6.
I have enabled the Autoconfig(Stateless).
As per my understanding the IP address will be created based on the MAC.
My MAC is 00:80:e1:00:00:00
Link local address is fe80::280:e1ff:fe00:0000
I tried to ping this address from my PC.
But host is unreachable.
IPv4 is working but IPv6 is not working.
I have attached my code below.
Please tell me how to solve this issue.
Thanks in advance.
