rtnet start failed on ubuntu24.04 with i226 nic

[linshiyuan]

Hi,

I follow the guide in Sanity Check 11 - Smokey  try to start rtnet but failed.

Is there some steps I missing ?

Hi,

Could you provide:

1. Which Edge Software package are you using?
2. Guide/documentation that you are referring to (to ensure you are referring to the latest guide)
3. Your hardware details

Cordially,

Iffa

Hi,

1. ECI Version: 3.3, ubuntu24.04

2. https://eci.intel.com/docs/3.3/development/performance/benchmarks/performance-testing.html?highlight=rtnet

3. I upload the output of lshw in the attachment. Is this OK?

[Iffa_Intel]

Thanks for the clarification.

1. For Sanity Check 11- Smokey you need to install Xenomai kernel. Have you checked & verified that you've installed this kernel?
2. In your case, it seems that the program failed to detect your Ethernet hardware, this could be related to the software(eg driver) or the hardware itself. Did you manage to grep the Ethernet hardware in step 1?
3. Are you using proxy in your system? 

Cordially,

Iffa

Hi,

1. Yes, I installed the Xenomai kernel,  I use uname to check and it is  6.6.23-intel-ese-standard-lts-dovetail.

2. The lspci -v output shows there is two driver igc and rt_igc available. My nic hardware is  226-v.

lspci -v

3.There is no proxy on my system.

On the same PC hardware, I can use rtnet with ubuntu22.04 and ECI 3.2 .  Is there some compatibility issues with ubuntu24.04 and ECI 3.3 ?

[Iffa_Intel]

Hi,

According to this ECI versions and Supported Distributions documentation,

the ECI version 3.3 supports Canonical® Ubuntu® 24.04 (Noble Numbat).

Could you try removing one of the drivers and using only the one that is compatible with your operating system to see if it resolves the issue? The program might be confused by the presence of both drivers.

Cordially,

Iffa

Hi,

Intel will no longer monitor this thread since we have provided a solution. If you need any additional information from Intel, please submit a new question. 

Cordially,
