If you get Philips to agree to disclosure of the full source, you
inspect and validate the source code yourself.

You can also use reverse engieering methods I explain here:

I use the exact the same timing parameters that is boot loader uses
and in your part.  The only thing I do differently is rather than
blindly wait for a given number of cycles (and hope the flash is
ready) I poll the flash status registers to determine when it is ready.

Check out exception handling in SILL at

It does not have a CSI so it cannot have CSI bugs.

See discussions in other threads here.

See the specifications of how the chip is restored.

You do not get this boot loader from Philips.  You fetch the image and
tools from the forum download area.

You do not *have* to use this boot loader if you do not need it.

Note:

1/  Philips *cannot* forbid you from runing your own code in the boot
sector.  (Different story if boot sector is in ROM).

2/  If you are concerned about warranty issues, make a backup of hte
original boot loader in your part, and just restore it before you
raise any warranty issues with Philips.

If you want Philips Certified/Appointed cosultant, you are better of
sticking to suppied boot loader.
