The card mode is

When Bluefield in NIC mode

No mlx5_rdma_enable_roce error.

How can I solve this problem in DPU mode?

Please help me.


I ran into your exact issue with a older BlueField-2 with stock firmware after flashing a DOCA 2.5 image. The issue seems to be related to the firmware on the card being too old. Both openibd and from DOCA 2.5 fail because of this.

Here’s how I managed to fix this:

  1. Flash the DOCA 1.5.2 LTS image from here using bfb-install.
  2. After installing the image, use the included /opt/mellanox/mlnx-fw-updater/ to update the firmware.
  3. Power cycle the host machine, then verify that the firmware has been updated using on the BlueField-2
  4. Install the latest DOCA 2 BlueFieldOS image
  5. Run /opt/mellanox/mlnx-fw-updater/ on the BlueField-2 again.
  6. Power cycle the host machine again

At this point, everything should work again.
