I used the eepromARMTool tool in order to program the NVM, but it seems that nothing is written to FLASH. Please let us know if this information is useful to you. This document is classified as Intel Confidential.
The Intel(R) Ethernet Controller I210 Production NVM Images document # 513655 has the production images archive contains a list of images and their features. It can be found in the Intel(R) Network Connections tools package for LAN controllers and adapters for various operating systems document # 348742. The EEUPDATE is used to program the flash memory or iNVM in production environments. This may also happen if the flash memory is not ready at the time that the I210 initializes, so it is important that the flash memory component be powered from the same source as the I210.
In case that the internal iNVM is not programmed for security feature the I210 assumes all hardware defaults, including a PCI ID of 0x1531. Thank you for contacting Intel Embedded Community.
