It seems to me as someone who designs and makes embedded devices (mainly
using the Freescale MC9S12 processors) that you need another lower level
bootstrap loader that is small, can be protected and will either jump to
the main bootstrap loader if it is functional or be able to download a

I would have thought it would be nice to avoid an extra chip. I noticed
after a quick scan through the documentation on the flash currently
being used by the Neo that there is one 16K block of OTP memory. Of
course this would only be any good if it could be mapped to the
addresses that get
Hi folks,
I would strongly support putting a no-way-writable ROM chip as this first
level boot loader. If there is no such option, I really wonder what is my
option if somehow it gets screwed up, other than the trash can? Is there an
always working solution to reset my moko?

Just had a further thought about what to do if the main bootstrap loader
gets trashed that maybe easier to implement. Rather than a stage 1
bootstrap loader looking to the USB interface for a replacement how
about looking on the SD card?

Yeah, we tried, but it just doesn't seem to be possible :-( There
are some alternatives, but they then lead to other problems, such
as chips not being available in quantity, etc. (And we've had our

If you do find a chip with a small protected page i might be interested
in writing the loader i have outlined.
Thanks !
As long as the bootstrap code reprogramming is bullet proof or you
don't see the need for changing the boot code i can't see any problems
with one

Ah yes, we've been through that idea as well :-)
We rejected it, because we don't want to
