Subject: [Gumstix-users] Pull CPU Serial from /proc/cpuinfo


Hi all,

Quick one for you guys...

I need to pull the serial number of the CPU of the gumstix from /proc/cpuinfo.

It's the very last line in the output:

Processor       : XScale-PXA255 rev 6 (v5l)
BogoMIPS        : 397.31
Features        : swp half fastmult edsp
CPU implementer : 0x69
CPU architecture: 5TE
CPU variant     : 0x0
CPU part        : 0x2d0
CPU revision    : 6
Cache type      : undefined 5
Cache clean     : undefined 5
Cache lockdown  : undefined 5
Cache format    : Harvard
I size          : 32768
I assoc         : 32
I line length   : 32
I sets          : 32
D size          : 32768
D assoc         : 32
D line length   : 32
D sets          : 32

Hardware        : The Gumstix Platform
Revision        : 0000
Serial          : 328e1362e7af4134

I just need the serial number, not the preceding text or spaces.  Any ideas how this might be done?

The closest I can get is to type "cat /proc/cpuinfo | grep Serial"
