MAC Address for Windows 10 IoT

[hankwang]

Hi,

      I have a MX8MP CPU and our MAC address needs to be written to the eeprom. Now, when the system goes into Windows, the i.MX Ethernet QoS Adapter fails to install the driver on the custom board. This is because the Ethernet QoS driver obtained the 00-00-00-00-00-00 MAC address.

      We want to read MAC address from the eeprom. Where do we need to modify?

     Please help us give some ideas. Thanks.

Hello @hankwang,

I hope you are doing well.

Please find the engineering team response given below.

what they please mend by Eeprom. External I2C eeprom or SoC Fuses?

Windows 10 IoT BSP uses internal fuses as storage for MAC addresses. It is than read with help of ACPI method _DSM. In this method there could be made changes, if the MAC shall be read from different address. E.g. from a RAM location, where some external EEPROM service routine stored it previously.

Thanks & Regards,
