Intel Atom EHL Ethernet
Re: Intel Atom EHL Ethernet
I think all Intel Ethernet controllers today are i2xx compatible. In my documentation of EHL v2 the Ethernet controller is called "TSN".
Another way to figure it out is to get the PCIe device identifiers, which in my PC are 8086 (Intel vendor) and 157B. This combination is described as i210 Gigabit network connection here: https://devicehunt.com/view/type/pci/ve ... evice/157B

Re: Intel Atom EHL Ethernet
Intel didn't make this Ethernet controller, they licensed it from Synopsys.
That's short for Time-Sensitive Networking. It's not the name of the Ethernet controller.
The PCH Ethernet controller is vendor 8086 device 4B32.
Re: Intel Atom EHL Ethernet
There is no online information about that device, so I cannot say. Still, I have two Intel EHL based computers, and both have i210 compatible Ethernet integrated into the chipset.

Re: Intel Atom EHL Ethernet
Not so. They are described in the chipset manual from Intel, along with a dual CAN controller and some other peripherials. This was typically the case for RTL Ethernet controllers, but the i210 is an Intel design.Octocontrabass wrote: ↑Fri Sep 27, 2024 2:42 pmIf you open one of them up and look, you should see a separate i210 chip that isn't part of the main SoC.

Hello Octocontrabass
i was able to to make my ethernet drivers to work,, it took me few sleepless nights to get there , but finally i was able to transmit ethernet frames

Re: Intel Atom EHL Ethernet
It's called the "Intel Atom® x6000E Series, and Intel® Pentium® and Celeron® N and J Series Processors for IoT Applications."Octocontrabass wrote: ↑Sat Sep 28, 2024 12:56 pmWhich chipset manual? The only Elkhart Lake manuals I've seen describe the Synopsys Ethernet controller.

Re: Intel Atom EHL Ethernet
That sounds like the same manual I'm looking at. Where in that manual are you seeing an Intel i2xx Ethernet controller instead of a Synopsys DWMAC4 Ethernet controller?
Re: Intel Atom EHL Ethernet
I just checked my computer, and there are no other PCIe ethernet devices than the two i2xx compatible controllers. OTOH, the two controllers appear to be on their own PCIe bus, and there are two chips on the board that might be Ethernet controllers. I didn't use the documentation in the manual, rather the manufacturer claimed the board had two i2xx compatible controllers, so you might be right about the function described in the manual. Maybe they can simply disable it?Octocontrabass wrote: ↑Mon Sep 30, 2024 8:53 amThat sounds like the same manual I'm looking at.

Re: Intel Atom EHL Ethernet
I find it fascinating that Intel has integrated Synopsys Ethernet into their chipsets when their own i2xx is so much better & properly documented. Doing some Googling on Synopsis, I think the answer is that they provide an Ethernet IP module for hardware designers that can just be plugged into their design, while the i2xx might be harder to integrate.Octocontrabass wrote: ↑Tue Oct 01, 2024 10:23 amThe datasheet says they can do that.
I'm not sure why anyone would want to disable the three built-in Ethernet controllers just to add a couple of external Ethernet controllers, but I guess they had some reason.
Re: Intel Atom EHL Ethernet
Hello Octocontrabass,
Want to evaluate the performance of i225 PCIE Nic, i got one from amazon and connected to the CRB it gets detected,
any suggestions about staring point, how to configure it and send messages ,, is there data sheet that you know ,, that can help me configure the NIC and test it
Thanks
Ravi

Re: Intel Atom EHL Ethernet
Section 4 of the i225 datasheet should cover everything.
If you don't have the i225 datasheet, I think section 4 of the i210 datasheet will be close enough.
