i210as SGMII mode

[yousuke]

I would like to use i210as in SGMII mode.

-Is it possible to change to SGMII mode by writing to iNVM? Or is it necessary to write to an external ROM?

-Are there any restrictions on external ROM? (e.g., 128 Mb or less, 4 KB sector erase, etc.)

-Can you give me a configuration file (.hex or .bin or .txt) for SGMII mode?

Hi yosuke,

Thank you for posting in Intel Ethernet Communities.

Could you let us know if you are trying to design a board with an i210-AS controller?

Best regards,

Hi Fariz_intel,

I apologize for not contacting you.

The board is already designed and I would like to connect it to an external PHY (BCM53162) in SGMII mode with initial settings via iNVM or external ROM (SPI).

Could you please answer my questions?

Hi yousuke,

Since it's related to the designed board with the i210-AS controller, we have a forum for those specific topics, and we are moving it to Embedded Connectivity so it can get answered promptly.

Best regards,

Hi Fariz_intel,

I will send you a schematic of my design.

SPI ROM is mounted W25Q80DVSSIG-ND.

R06832,R06833,R06834,R06835,R06836,C06821 are mounted.

Best regards,

Hello @yousuke,

Thank you for contacting Intel Embedded Community.

You can check the Intel® Ethernet Controller I210/I211: FAQ.

2.16 What NVM image should I select for the I210?
The production images archive (document 513655) contains a list of images and their features. The SGMII image is intended for use with the I210-IS when interfacing with an external SGMII PHY and controlling it via the I2C or MDIO interface. When connecting to an SGMII switch, use the appropriate KX image.

For the image, you can check the document #513655 - Intel® Ethernet Controller I210 and I211- AT Production NVM Images.

You will need a Premier account in order to get access to this document.

Hello Diego_Intel

I tried using eeupdate 513655 but it appears that only iNVM and MAC can access it.
What command is needed to access externel Flash?

Best regards,

Yousuke
