Gateway connecting to multiple controller over ethernet

[Balakrishna971]

Hi Team, 

I want to build a network of controllers/ECUs connecting to gateway(goldbox) over ethernet. There are few ECUs with only one ethernet port and it is required that ECU to connect to Gateway and another ECU, Please suggest what's the best way to interconnect these systems and communicate easily.

Thanks,

Bala

Hi balakrishna,

if you are using S32G2 Goldvip Box then its should has 5 Ethernet ports. in that 3 are based on PFE which is Ethernet packet forward engine and GMAC for Ethernet connection.

based on PFE_Mac0/1/2 need to configure to connect multiple board and the Data Transfer. I guess u might be working on Zonal Architecture.

Viswa

Hi Viswa,

Yes, I'm working on the Zonal Architecture.

Thanks,

Hi @Balakrishna971,

Hope you get the answer.

Please let us know if you have any queries about it.

Hi Mayank,

I have one small question, in this kind of architecture can the another board that is connected to Goldbox access the internet (internet access is avaialble for goldbox)

Hi @Balakrishna971, 

Ideally, other board is connected on PFE interface doesn't get internet access from the board but I have to double check the same.

Hi Mayank,
Sure, please confirm the same.

Hi @Balakrishna971,

Once you try to use SJA1110, the internet can be accessed on another board.

you can try a defined sample application for the same.

Hi @Balakrishna971,

I don't understand the use case which you described.

Please describe the use case in detail so we can properly help to you.

I am not understanding the part as some of the ECUs have one ethernet port that connects with another ECU and Goldbox. 

Are you looking for a wired solution or wireless solution or a mix of both?

Thanks,

Hi Mayank,
I'm looking for a wired solution, I want to connect a Goldbox with IMX8 and other multiple ECUs over ethernet so that all are in the same network and interchange the data among the ECUs.

My question is , can we leverage SJA1110 ethernet swtich avaiable on the goldbox for the connection or we need to use an extra switch to interconnect all the ECUs.

Thanks,
Bala

Hi Bala,

I like share my knowledge: SJA1110 is an switch between SOC to Ethernet ports. If PFE only enabled is not enough, SJA1110 also need to flash the firmware. Then only Ethernet ports packet will reach to SOC and PFE module based on your configuration. you can find these details in PFE code. 

If you start with PFE example code then all details you will come to know.
