How to select a stable uboot source code for developing a commercial product?
Just use the latest offical release (unless there are specific reasons not to).
So, how to identify which package is more stable than another package?!
U-Boot provides bug fixes to releases when really needed. Usually this is not the case. Exceptions were v2009.11.1, v2012.04.01, and v2013.01.01. IN all other cases, the release is "stable" enough.
For PandaBoard (TI Company):
It seems TI selected u-boot-2012.10.tar.bz2 as its code base.
But the latest release. v2013.07 also supports it so why would you got for a version that is already 9 months old?
Just use v2013.07.
Best regards,
Wolfgang Denk
