HPS ENET (EMAC) MAC Address failed to set

Hi All, 

 

I'm working with ArriaV SX.  

 

I'm receiving the following message from U-boot:  

 

Skipped ethaddr assignment due to invalid EMAC address in EEPROM Net: mii0 Warning: failing to set MAC address  

 

What's the problem? How to fix?  

 

In the QSys I've enabled the EMAC1 HPS Set0. 

 

Thank you

Where should the MAC Address be stored? Should it be inside of HPS or in the external PHY device?

In case the MAC should be stored in the external PHY device, should the HPS EMAC access it using its regular GMII pins?  

 

What's purpose of I2C Controller in the EMAC? Must I use/enable it in some way?

mind to know are you using the supplied prebuild SD card for boot up?

No, I don't use any pre-build SD card for the boot up... The boot is done using PreLoaded/U-Boot in ArriaV.  

 

I know that I can set the MAC address using the U-Boot command and then store it into a Flash... Can I set any MAC address? Should not I buy it for some organization (like IEEE or ITU) or probably notify them that I'm going to use a specific MAC address? Should not I receive their approval?  

 

The ArriaV HPS has two eMAC IPs... So can I set two different MAC addresses? 

 

Thank you!
