Unique ID

Hi,
I need an id on mini2440 which should be unique.

Is there any way to learn?

Thanks,
Muhammed ER.

To learn? Well, you can use the mac addreess as a unique id to identify a
mini2440... it that what U want?

Unfortunaly, the 2440 (nor the 6410) doesnt have a unique mac address. 
i suggest writing one to eeprom, that will also survive flash updates

remco

By the way anyone know how retrive any unique ID, Serela Number or any
other unique information from board?

The unique also means that it could not be changed out of manufacturing.

Thank you in advance.

faund, sharing here:

armel debian loading from SD 
use lshal 
get mmc.serial

exactly what I need!

Sorry I did not understand. Do you mean that we should use the SD or MMC
card's serial number and hash it using SHA1? I need something that can 't
be removed maybe an EEPROM. Too bad that EEPROMs can be removed. Ideally
this would be a serial number in the CPU, which is the most complicated
component to replace.

i'm using the eeprom for that.
i've split up some components at differtent boards (IP board, display board
and controller board and so on) and placed an eeprom at each.
this contains the serial and some other info for the running firmware to
start different the needed services.

best regards,
Willem
