Re: [Gumstix-users] Verdex serial numbers?

[Matt R. <me...@co...>]

First of all, thanks for a great product!  these little units have squashed
our development time.

I'm having trouble getting u-boot to generate unique serial numbers (which
seems a little odd, since I imagine that somewhere in the process, a
hardware serial number must be involved).  I found this advice in the
archives, but it doesn't seem like it's working for me.

It's not entirely clear to me whether this refers to an actual u-boot
version, or a particular version of the gumstix buildroot patches that get
applied.
It seems that there is a substantial amount of patching that needs to be
done in order to get a particular u-boot version functioning -- I tried
briefly with 1.3.0, but it seemed like getting that running would be beyond
my current skills (and require more time than I'd like to spend).

If my assumption that it's the buildroot version that makes the difference
is correct, can someone point to me to a version that works?  I've tried a
number of them with no success.  Usually the serial numbers look like random
hex strings, which is promising, but then after flashing a few units, they
repeat.  Other versions seem to generate things like 123456ffffffffff.

This is also fairly time-consuming to test (actually, nearly impossible to
test conclusively, but you get the idea...) , so any pointers would be
greatly appreciated.

Thanks!
Matt
