Although, to be honest, this is very handy for me because these are the MAC addresses that have been assigned to the MPC8349E-mITX board in our lab. This way, every time I build an image, it's guaranteed to have the right MAC addresses. I don't need to run some kind of script to set up my variables.
I understand that it may be handy for you, but it may be a debugging nightmare for your users, and it may generate a lot of support calls.
Is there some easy way for me to specify personalized config options at build time?
Use a script to auto-install your board. Expect is a great tool. Or at least make sure that these settings never go out to a customer, i. e. make sure they are fixed during production (probably when you save serial numbers etc.). But IMHO it's definitely better not to have these build in at all.
I agree, but if every board has the same flash image, how do we specify a different MAC address for each one?
Normally you do this during production. It depends how your boards are manufactured and tested - if testing includes to boot the board at least once, then this is where you can add such customization.
I don't see how. Not every company has a manufacturing process that
See all my previous postings.
allows that. This is especially true for reference boards, which aren't supposed to be used in a public environment anyway.
Ummm... all Freescale reference boards that make their way to a customer run in a "public environment".
Anyway - there are standards which shold be adhered to, and they make it pretty clear that you must not use the same MAC address for more than one board.
