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.” ???
From the Jetson_AGX_Orin_Design_Guide_DG-10653-001_v1.0
Thanks

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

@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
Thanks

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.
