How to access flash memory of LPC2106

[cippalippa]

Hello,

I'm new in the microcontroller word and I try to use the LPC2106 for a litte project.
I need to write the micro's flash memory when the firmware is running (in order to save some user data, like address, name etc...); may sameone say me if is possible and how can I do this?
thanks in advance

Flash access LPC2106

I'ts impossible to write the flash while the Lpc is running! The only solution is to run it from a external Sram! Or use a External memory.

Well, that is most definitely a wrong answer from Cortex,

"I'ts impossible to write the flash while the Lpc is running!"

Wrong

"The only solution is to run it from a external Sram! Or use a External memory."

Wrong again.
1. there is no external memory bus, so there is no external code execution.
2. You can run from internal SRAM while programming the Flash, in fact the only time you need to run from the SRAM is sfter issueing the program command through IAP and before you get the "done condition"
