How to read & write in programme-memory through programme in lpc2148?
In lpc2148 we hv 512kB flash memory, we want to use some of the flash to
store data. how we can do this?

Thanks

I have read it.But i think that it programmes Flash in running mode. Is
it right?.Actually i want to store input data in Flash during running
mode & whenever need comes,I want to read it & gives output to another
peripheral.It means i want to use internal Flash like external memory
storage device(use of 64K from 512K Flash)I am confused that,if i use
IAP,it damages my Boot programme of LPC2148? So if u have any suggestion
or code then Plz give it me.Tkank you once again........................

IAP can be used to write flash-sectors and to erase flash-pages from the
user-application.

Which boot-program? A secondary bootloader? Just make sure that the
address-range used for the emulated "external memory storage device"
does not intersect with the address-range with the "boot programme"'s
code.
