Template:FAQ/Questions/a software accessible unique

Is there a software accessible unique serial number on the gumstix?
Yes, there's a serial number on the flash chip, which is software-readable in u-boot as the 'serial' environment variable. This is passed to linux and shows up as the linux kernel serial number, which can be obtained from /proc/cpuinfo

The bluetooth MAC is also unique if you have a bluetooth gumstix. You can obtain that with &quot;hciconfig&quot; after loading the bluetooth driver and starting the bluetooth subsystem.

The /proc/cpuinfo number would be the better method to use.

Note: It's intel strataflash. The factory programmed 64-bit portion of the Protection Register is unique across all flash memory product lines. It can be thought of as a serial number; Therefore, as every Intel chip has different factory programmed portion of the Protection Register, every gumstix basix or connex platform can be uniquely identified.
