[yocto] :how to solve the basehash value changed from 'xxx' to 'aaaa' ?

[Mark Hatle]

You are changing the value of something in there dynamically.  Most likely
you've done something like embed the current date and time.

If you do something like that, you need to evaluate it -once- during parse time
and not again.  This will fix the hash value at parse time and not change it later.
