Error when trying to check if NV access registers are supported

[kiki639]

I'm trying out a Bluefield-2 DPU.

BlueField-2 DPU was installed on the server, but rshim was not recognized.
The server only has DOCA installed.

I found that NTERNAL_CPU_MODEL on this card is SEPARATED_HOST(0).
So with reference to this article, I changed it to DPU mode.
https://docs.nvidia.com/networking/display/bluefielddpuosv390/modes+of+operation
mlxconfig -d /dev/mst/<device> s INTERNAL_CPU_MODEL=1
sudo reboot

However, the following appears every time you use the mlxconfig command.

# sudo mlxconfig -d /dev/mst/mt41686_pciconf0 q
-E- Error when trying to check if NV access registers are supported

What's going on?

Hi,

Thank you for reaching out.

Please note that after running the mlxconfig set command, a full power-cycle is required — a simple reboot will not suffice.

Kindly perform a power-cycle and check if the issue is resolved. If the problem persists, please share the following details to help us investigate further:

MFT version (mst version)

Firmware version (flint -d q)

Looking forward to your update.

Best regards,
Ahmad
