Hi, I want to use a connectx4-lx on Jetson AGX Orin with L4T 36.4.7 version.

I want to use RDMA protocol (RoCEv2).

I recompile the linux infiniband module

But I have this message when I trie to load mlx5_ib

sudo modprobe mlx5_ib

sudo dmesg -w → ib_uverbs: Unknown symbol hmm_range_fault (err -2).

Best regards

Hi,
We don’t support the setup on AGX Orin. Would suggest check IGX Orin:
System Overview — NVIDIA IGX Orin - User Guide

It is with NVIDIA ConnectX-7.

Hi,

I use connectx 4LX board on the pcie express slot of the orin AGX devkit.

IGX orin use the same Soc so I don’t understand why rdma is working on igx but not on the agx version.

Best

David
