TE-0720 EUI-48/64 Unique ID

[bigguiness]

Hello,

Is it possible to read the EUI-48/64 Unique ID on a TE-0720 board from Linux?

What is the size of the Unique ID?

Thanks

Hello,
we have implemented they why to read EEPROM MAC on our reference design.
This will be done over MDIO interface of the CPLD.
1. FSBL Read MAC over MDIO interface
2.Uboot set MAC Register for linux
3.Linux use this MAC

See  reference design.

What is the size of the Unique ID?

what did you mean?
We use 11AA02E48

John,

Thanks for the information and links. I will review them.

As far as the size of the Unique ID. 48-bit is what I needed to know. I have a need for a 64-bit value but the 11AA02E48 shows how to create an EUI-64 from the EUI-48.

Thanks,
Hartley
