How to share the internet from GMAC0 ethernet port on NXP S32G to other ethernet ports ?

[girkulkarni]

I have flashed the SJA1110 firmware , but not able to share the internet from GMAC0 port to other devices connected to ethernet ports on S32G . Tried to enable SJA1110 on S32G with default sja1110_switch.bin from Goldvip 1.5.0 .  

Also followed ethernet enablement guide from NXP Website to enable sja1110 switch . (Screenshot attached ) . But not able to get the IP for the  PC connected to goldbox .

Please find the below logs

Hi, 

thanks for your answer. The steps I shared described how to enable Pfe and then you can connect corresponding ports according to which PFE interface is used.

Hi Sabeur,

            Are we making use of SJA1110 switch in this case ? Also will this share the internet from GMAC0 port  to SJA1110 ports? Because SJA1110 switch had multiple ports which would be helpful for us to connect multiple devices and communicate with Dom0 and Domu on goldbox.

Hi, 

What SW is used on the S32G ?
The best is to follow the steps described here: https://www.nxp.com/document/guide/getting-started-with-the-goldbox-for-vehicle-network-processing:G...

in Projects and Tutorials -> PFE Ethernet interface with LWIP and FreeRTOS

regards,

Sabeur

We will be connecting a hardware/device to nxp s32g gateway and our requirement is to get internet access to connected hardware through goldbox so that connected device and goldbox can communicate over ethernet

@girkulkarni you are running the Linux BSP on S32G?
