Lpc2000

Hello!

For my projekt i am using a lpc2292.

My problem is the following:
Since my application is without the possibllity to use the build in
bootloader, i want to write my own boot loader which can be
controlled via software!
I imagine that i can reseve a areaa of the flash for the bootloader
so it will always be present even if programming is failing.
My questions are:
how do i place the bootloader on a specific adress area in the flash
memory??

how do i reserve this area so my next application will not use this
area of the flash memory?

I expect the bootloader to use the internal programming routines to
program the flash, but the new data to be programmed will be placed
on a SD card or something like it, must the boot loader run from
flash or internal RAM?

if you have a link for some pages descibing simmilar
problems/projects or som codepieces i will be recieved with
appreciation.

Thans a lot
Best regards
