Hi @chenyin_h

Whether this LWIP needs to be implemented in S32G or SJA1110 ?
I am looking to use IPv6 address to Tx and Rx and completely replace with IPv4 address with IPv6 address in Transmission of Message
How can i bring up IPv6 Address ?
Where the code needs to be integrated which files will be creating? So give me a Example for the IPv6 bringup
what setup need to be done to implement in lwIP stack IPv6 after enabling it

Regards
Atkinson

Hello, @Atkinson

Thanks for the post.

1. LWIP is a software stack, usually the code is running with host, it is suggested integrating it to your M core application, regardless the network traffic to sja1110 or to PFE directly.

2. Currently there is no directly IPv6 samples existed, there is a LWIP bare metal example, which is using the GMAC interface, you may firstly use it for your reference.

It is by default using the IPv4, and you will need to change the code to try with IPv6, there is not public document from NXP for describing it, I suggest directly reference the introduction from LWIP, for example: https://www.nongnu.org/lwip/2_1_x/group__lwip__opts__ipv6.html
