Questions regarding multi-core networking in S32G399A

Dear NXP fellows,

I am investigating how to setup the network interfaces of our S32G399A-RDB3 based custom board. This board uses BSP 41.0.

Actually, there are 3 PFE interfaces available:

PFE_MAC0: Connected through SGMII to the SJA1110A switch port 4;
PFE_MAC1: Connected through RGMII-ID to a 1000BASE-T1 PHY;
PFE_MAC2: Connected through RGMII-ID to a 1000BASE-T1 PHY.

All of these interfaces are up and running. I can assign IP addresses in different subnets for each of them and I am able to ping my laptop connected through an adapter and vice-versa.

When I took a look at one internal requirement for the configuration of the IP addresses and VLAN IDs, I saw this specification:

Server Server IP VLAN ID Port S32G_Mcore 192.168.10.10 10 50102 S32G_Mcore 192.168.12.10 12 50102 S32G_Mcore 192.168.13.10 13 50102 S32G_Mcore 192.168.14.10 14 50102 S32G_Acore 192.168.10.11 10 50101 S32G_Acore 192.168.11.11 11 50101 S32G_Acore 192.168.12.11 12 50101 S32G_Acore 192.168.13.11 13 50101 S32G_Acore 192.168.14.11 14 50101

In this case there are a total of five subnets:

192.168.10.X, 192.168.11.X, 192.168.12.X, 192.168.13.X, and 192.168.14.X

And there are different IP addresses for the S32G M7-core and the A53 core.

All of the subnet masks are 255.255.255.0.

How can I assign a different IP address for M-core and A-core? Does it imply using PFE Master-Slave configuration?

Can our board fulfill this specification?

Thank you very much for the support.

Best regards,

Guilherme

Hello, @GuilhermeS32G

Thanks for your post.

From the description, from my opinion, you could try the PFE master/slave example(M core master/A core slave for example). And then create vlan based on differnt emacX for both M&A core side according to your requirement. I think it is possible and supported.

Hello @chenyin_h ,

That's good to know that this setup is supported.

Then I will read the documentation about PFE Master/Slave configuration, try to enable this feature and if I face some issue I may open a new topic.

Thank you for your support,

Best regards,

Guilherme
