Hello!!..  Bootloader...
Why not you do something more fantastic for group members here:

=>Something that able is to copy the bootloader from one chip 
to another.

ARM7 firmware #1
- Name "SOURCE.HEX"
- Burn onto chip #1 with newer bootloader

ARM7 firmware #2
- Name "DESTINATION.HEX"
- Burn onto chip #2 with older bootloader

Then
- Connect the 2 chips through UART0.
- Power up the 2 chips together
- Bootloader automatically get copied from Chip #1 to Chip #2
- Chips toggle Txd line at 1Hz once completed copying.

I guess quite some people here will use it.   And no longer need
to wait for Philips releasing of BootLoader Upgrade.

Better if you can make it more plug and play.  You can keep
your source code.   Only need to promise you do not plant a 
Trojan-horse onto the chips.  :)

What can philips complain??  as long as you do not modify
some flash memory area you called "bootsector" (or bootblock??)
May be philips will thank you, Umm...I mean unofficially   :)
