LPC2478 or LPC 2468 Bootloader Options / Questions

Started by robinsm123 January 29, 2009
I'm thinking of getting a developement board for either LPC2478 or LPC
2468. I just have a few questions regarding a bootloader.

1. Is it possible to completely remove the Phillips boot loader and
just use my own?

2. If not, Do I have to jump to sections of the phillips bootloader in
order to write to flash, or can my bootloader be completely independant?

3. What are some good refernece documents for writing bootloaders for
LPC.
