EEPROM Access Tool for ARM (Intel I226)

AxitSoni — Tue, 30 Jul 2024 13:04:04 GMT

Hello Intel Team,

We are having Intel I226 Ethernet Phy Controller connected with Embedded Platform which is QCOM ARM based SOC connected over PCIE Interface.

We need EEPROM Access Tool for Flashing and its Usage Guide.

We are using the Linux Kernel Driver (igc.ko). But its causing the ERROR.

igc 0001:01:00.0: The NVM Checksum Is Not Valid

Code:

if (igc_get_flash_presence_i225(hw)) { if (hw->nvm.ops.validate(hw) < 0) { dev_err(&pdev->dev, "The NVM Checksum Is Not Valid\n"); err = -EIO; goto err_eeprom; } }

Please help us with the EEPROM Access Tool and Its Flashing Guide.

Thanks

Hello @Diego_INTEL ,

I got the RDC access. I downloaded the EEPROM Access Tool. But when executing the NIC dump command. I see no NIC present for Intel I226 Chipset. Please check below snippet.

/data/eepromaccesstool-0.8.0 # ./EepromAccessTool Intel(R) EEPROM Access Tool NVM/OTP Programming Example Tool Version 0.8.0 Provided under the terms of a CNDA. Do Not Distribute. Copyright(C) 2017-2020 by Intel(R) Corporation NIC BUS DEV FUN Silicon Memory Type Present === === === === ===== ======================

Can you please guide whether and how we can use this EepromAccessTool with Intel I226 Ethernet Controller ?

Thanks,

Axit Soni

Hello @AxitSoni,

My apologies for the delay, also I forgot to mention the following:

The i225 and i226 are not supported for ARM, but it is possible to use the EEPROM Access Tool with the i226 by adding the device IDs mentioned in the datasheet, document #596659, in section 5.1.1.8 Device ID - 0x000D.

Please check this post, the user Andy helped a lot by sharing their patch, so you can check the implementation.

I was looking for a way to configure the flash and MAC address of an i226 on an ARM CPU. You mentioned adding a device ID; could you please explain in detail which parts of eepromaccesstool I need to modify and how I need to run `make`?
