Can two Orin SOM connected through UPHY

Hi nvidia teams:

Our design uses two Orin SOM to achieve our target.
There are some date need to be transmited form One SOM to another.
So I want to ask the design below is ok or not?

phy-iface-mode is XFI 10G

UPHY8 as MGBE and MAC to MAC connection?

Yes :

In our design , two orins need data transfer,through UPHY8 as MGBE and MAC to MAC connection.

So you want to use config #3?

Yes:
I know config #3 is not yet fully supported,but I think it is most suitable for us.

Hi,

Actually, config #3 won’t be supported. There would be announcement soon.

why won’t be supported ? any difficult problem?

Will it not support CONFIG#3 in the future?

Yes, it will not be supported.

Does this mean that the Orin will never support 4 10GbE? That is a pretty major capability to decide not to support after promising at launch.

Hi NV Team
Can you please clarify detail for UPHY config#3.
What is means “Actually, config #3 won’t be supported. There would be announcement soon.” ???

We will release a adaptation guide document soon and it will show config#3 not supported.

Should be in this link.

Hi Wayne
I double check the documents. “Adaptation_and_Bringup_for_Jetson_AGX_Orin” UPHY setting.
Below is my understand, Please help confrim.
The config 1 dont support MGBE. Change to PCIex8
The config 2 PCIex8 change to PCIex4 and MGBEx4.
The config 3 dont support in future.

Thanks
Yutai

@WayneWWW
Any update about the phy mapping ?
Below is my understand, Please help confrim.
The config 1 dont support MGBE. Change to PCIex8
The config 2 PCIex8 change to PCIex4 and MGBEx4.
The config 3 dont support in future

No, your understanding is wrong… please check the design guide document.

@WayneWWW
Sorry, Some confuse your comments. config#3 not supported.
But from the “Adaptation_and_Bringup_for_Jetson_AGX_Orin” The Lane4,5,6,7 support MGBE0,MGBE1,MGBE2,MGBE3
So can you please give me detail clear description for each UPHY Lane support feature in both config 1 and 2.


Thanks
Yutai

Please just follow the design guide. Only pure config #1 and #2 are supported. Same as what the design guide shows.

Q1. Why “Adaptation_and_Bringup_for_Jetson_AGX_Orin” dont match design guide ?
Q2. You means we must follow up “Jetson_AGX_Orin_Design_Guide_DG-10653-001_v1.0” Table 6-4
Only config #1 and #2 support, #3 dont support.** It is final decision from NVIDIA?**
If YES, please update design guide.
