IPv6 Configuration @ RDB32

Atkinson — Tue, 08 Jul 2025 10:38:14 GMT

Hi,

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 ?
what setup need to be done to implement in lwIP stack IPv6 after enabling it
Looking forward for reference documents with respect to IPv6 in RDB Board
To replace the IPv4 with IPv6 how to do ? whether it is possible to replace?

Regards
Atkison

Hello, @Atkinson

Thanks for your post.

1. Seems you are working with M core application? are you using the S32G - TCP/IP Stack? if yes, which version?

2. In general, the latest S32G - TCP/IP Stack released by NXP is based on Lwip2.1.x, as a result, the IPv6 could be supported, for the details guide for using/setting the stack, I suggest referencing the official document from https://www.nongnu.org/lwip/2_1_x/group__lwip__opts__ipv6.html

Hi, @Atkinson

Thanks for your reply.

I am wondering the accurate version number of the S32G TCP/IP Stack, which version you are using from the following?

In general, by default, ipv6 is not supported, by setting the following to 1 would help to enable the ipv6

Hi @chenyin_h

I am using the TCP/IP lwIP version - "SW32G_TCPIP_1_0_4_D2310_updatesite.zip"
I could see in code that i have option IPv6 enable and also i Have a option in TCP/IP middleware configuration ---> where i have ENABLE IPv6 option
I am looking to use IPv6 address to Tx and Rx and completely replace with IPv4 address with IPv6 address in Transmission of Message
I am looking for a option to completely replace IPv4 with IPv6 address
Making a primary utilization of IPv6 in all aspects how to implement?

Hello, @Atkinson

Thanks for your reply.

With the settings for enabling IPv6, then the stack would support both ipv4 and ipv6, if you do want to only use the ipv6, then undefine of the ipv4 would be required.

Besides, you may need to set a ipv6 address for the test, for example,

netif_create_ip6_linklocal_address() API could be used, for details, I suggest checking the official site of lwip

https://www.nongnu.org/lwip/2_1_x/.

Hi @chenyin_h

The IPv6 needs to implemented from SJA1110 switch or S32G Processor which one it need to be done?
So how can we make a communication via IPv6 using LWIP how to derive a Standalone use case in implementing it.
