i210 Device off function issue

[PWu3]

Hello Intel,

I used i210 device off function, and look datasheet 6.2.19 bit15 setting to 1b.

So I change value B200 at address 0x1E.

And circuit used jumper JP_LAN2 setting pin.28

Then have two setting

1. 1-2 : Enable Lan i210

2. 2-3 : Disable Lan i210

Test jumper JP_LAN2, and setting 1-2 then power on.

It can see i210 operation under windows 10.

Test finish, shunt down windows.

I will setting 2-3 at JP_LAN2. => Power on => But still can see i210 operation under windows.

I need disable i210 after shunt down windows again.

What does mistake in circut or i210 code ?

Best regards,

Hello, wupatrick:

Thank you for contacting Intel Embedded Community.

In order to be on the same page, could you please tell us if the affected units have been designed by you or a third-party company? By the way, could you please let us know how many units are associated with this condition?

Finally, could you please verify that you have followed the DEV_OFF_N pin guidelines stated in sections 5.2.6.1, 4.4.4, 3.7.8.5.7, 4.4.2, 5.4.3, and 12.8; on pages 162, 144, 124, 143, 165, 836, and 837 of the https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/i210-ethernet-controller-datasheet.pdf Intel(R) Ethernet Controller I210 Datasheet document # 333016?

Waiting for the information that should answer these questions.

Hello Carlos,

Thank you for your information!

I try to complete verification, and followed the guidelines stated of the document # 333016.

Still get same result

But i210 have another problem.

When Power is ON

I setting JP_LAN2 1-2 to 2-3 => shunt down => i210 ensure disable

It needn't shunt down again! (JP_LAN2 2-3 to 1-2 same result).

By the way, the APM Enable (Word 0x24) function. I need setting to 0b, when use Device Off function?

Hello Carlos,

Sorry, i didn't notice.

Yes, this circuit designed by me. And many case will use Dev_off function in the future.

Thanks~

Hello, wupatrick:

Thanks for your reply.

Based on your previous answer, could you please let us know the sources that you have used to implement your design? could you please tell us if the schematics and layout of your project has been reviewed by Intel?

Waiting for your answer to these questions.

Hello Carlos,

My design source form Intel® Ethernet Controller I210-AT/I211-AT: Schematics. https://www.intel.com.tw/content/www/tw/zh/embedded/products/networking/i210-at-i211-at-1g-base-t-reference-design-schematic.html https://www.intel.com.tw/content/www/tw/zh/embedded/products/networking/i210-at-i211-at-1g-base-t-reference-design-schematic.html

Schematics mostly the same with reference schemaric pdf file.

Only dec_off_n function have used jumper setting to change pull-high or pull-low.

Controller ON or OFF i210-AT device.

I was review i210 datasheet, and found "asynchronous" on table 2-8.

What does this mean?

As stated before, change jumper 1-2 or 2-3 under OS.

Next restart system, then function was normal operation (can enable/disable i210) .

Can tell me this operator was sure?

It dev_off function in connection with intel Management Engine?

Thanks~

Hello, wupatrick:

Thanks for your reply.

In order to be on the same page, could please clarify if the device simply showing up in device manager or it is able to pass traffic too?

Waiting for your reply to this question.
