Intel I225-IT Ethernet controller bringup issue

[shivbalaji]

Hi All,

We are using I225IT Ethernet controller for our project on i7 8^Th gen processor and it is connected to PCIe port.

We could see the PCI device ID as 0x15FD and also see the IGC Linux(5.6.19) driver is probing but its failing while reading PHY device id(Reading zero always) and it is failing due to IGC_ERR_PHY(-2).

Did comment PHY ID check on the driver and later could see the interface details but there is no link and speed details on the interface. Could anyone provide insights for PHY error on I225IT?

I225-IT ethernet controller also connected to the 1MB SPI NOR Flash and PHY section(0x7F0) on the flash reads 0xFF.

Do we need firmware update for this I225-IT controller? We don’t see firmware version details for this interface using ethtool, it looks empty.  Could anyone provide details ?

Thanks

So, We understand this is the I225 Default device ID (0x15FD) which is having empty flash image. Could anyone post the details of flashing the NVM?

Hello, @shivbalaji 

As you can check here: https://github.com/torvalds/linux/blob/master/drivers/net/ethernet/intel/igc/igc_phy.c

/**
* igc_setup_copper_link - Configure copper link settings
* @hw: pointer to the HW structure
*
* Calls the appropriate function to configure the link for auto-neg or forced
* speed and duplex. Then we check for link, once link is established calls
* to configure collision distance and flow control are called. If link is
* not established, we return -IGC_ERR_PHY (-2).

This points to a failure on link configuration.

Please provide the following information:

1) What Linux distro are you using? Does the issue occurs on other Linux distro?

2) Since the controller is connected via a PCIe port, does the issue occurs on a different board?

3) Are you the manufacturer of the I225 PCIe card?

4) Have you tried using a different Ethernet PCIe card on your board?

5) Did the board undergo a schematic and layout review from Intel?

6) Is the board manufactured by your company or by third-party vendor?

Best Regards,
