Solved: Ethernet Compliance Test I210-AT 10Base-T/100Base-TX - Page 2

AStoj1 · ‎05-16-2018

Hi

I want to run Ethernet Compliance Tests 10/100Mbps with I210-AT.

Are there any information available? I can not find anything in the datasheet.

E.g. create 100Mbps MLT-3 Random Test Pattern.

I can only find Test Mode Register Bits (15:13) in 1000Base-T Control Register (Page 0, Register 9) for Gigabit.

What is the purpose of 100 MB test select bits 3:2 of Copper Specific Control Register 3 - Page 0, Register 23 ?

What can I do with the PRBS Control - Page 26, Register 23 ?

Thanks for your help

Hi,

I can access MDIO Phy registers to fullfill, for example,
"Write MDIO Phy Register 0x10, Set Value to 0x0" :
sudo mdio-tool w eth1 0x10 0x0

How can I access the MAC registers to fullfill
"Write MAC Register 0xE14, Turn off bit 5" ?

Best,

Hello Carlos_A., Andrija

I am still waiting for the CNDA to be granted, still no feedback at all. I sent e-mail to Janella Ruth from the support team, and she's checking the status of my request.

By the way, I tried the test with the information Andrija wrote 4 weeks ago and I made the tests. But I didn't use the register at the address 0x1A, what works for me to generate pseudo-random pattern for the 100Mbps test are the following registers :

Set the duplex and speed fixed without autoneg : page 0 reg 0

Set copper port packet generator page : 6 reg 16 bit 3, 2 and 1

I'll make the 10BASE-T test today and let you know.

Thank you, both of you, for your help.

Andrija, ,

I've tried the procedure you sent the 6th of June and unfortunately it doesn't work for me for the 10BASE-T compliance test at all. Even for the TP_IDL test there are no idle pulses. I followed the setup settings (I read the initial value and then write with the corresponding bits):

o Write MDIO Phy Register 0x10, Turn off bit 10 ->> I set it to 0x3360 (same value than the read one)

o Write MDIO Phy Register 0x1A, Turn off bits 2 and 3 ->> I set it to 0x0400(same value than the read one)

o Write MAC Register 0xE14, Turn off bit 5 ->> I set it to 0x0000008d (same value than the read one)

o Write MDIO Phy Register 0x10, Turn on bit 10 --> I set it to 0x3760

o Write MDIO Phy Register 0x16, Set value to 0x6 --> change the page to page 6

o Write MDIO Phy Register 0x10, Set Value to 0x0 --> I set value 0x0 to the register 16 of page 6

o Write MDIO Phy Register 0x16, Set Value to 0x0 --> change the page back to 0

o Write MDIO Phy Register 0x0, Set Value to 0x0 --> I set it to 0x0 (even if I don't understand why we configure the link in 10Mbs HALF duplex, Do we need to use a link partner?)

Nothing happens on my captured signals, the TP_IDL test is failed as all the others.

I'am really stucked for these tests, and still don't know where my NDA request achievement. I think that my company already have one with Intel(we use a lot intel components on different projects), but I don't know how to find it.

Andrija, have you made the test yet?

Hello, celinel:

Thanks for your update.

Please inform us if you still need our support through this channel, since Andrija usually prefers to contact you via email.

Hi Carlos_A,

I have been in touch with the IoT market responsible in France, and normally we will call each other for this problem of compliance test. We indeed have a valid NDA so I'm waiting for the priviledge access to read the document you cited before.

In the meantime, I think I succeed to test the i210 with a link partner, and I didn't use at all the previous configuration, I just wrote into Page 0 reg 0 to set the speed at fixed 10Mbps Full Duplex mode, and I accessed the Page 2 register 21 to set the bit 14 in line loopback mode. I still have some failed results, and I don't know if it's due to my test setup or my board routing, so I'm analyzing these results.

I still want some formal document from Intel to approve the way I tested the component because we develop aeronautical product and this mean formal testing and certification.

Thank you if you have further information about this component testing.

Thank you also Andrija for your help.

Regards,

Celine
