Hi All,

I am using lpc2103 for my application. The application is such that some of the parameters are required to be stored into and retrieved from the flash memory during run time. So, is it possible to read from and write into the lpc2103 flash memory during run time?

Kindly provide the available solution for this issue.

Thanks. Start a New Thread

Read about IAP in the UM.

Hi,
 
        Thanks for the solution. But is it possible to read from the flash memory during run time using IAP commands? If so then please provide the IAP commands for the same since these kind of commands are not given in manual.

You don't need IAP to read flash. All flash is mapped to memory, so
just read data from the specific address you want.

You can read of flash using the pointer to the address requested.

Code exemple:

#define ADDR_FLASH 0x0007C000;

unsigned int *pFlash;
unsigned int flashValue;

pFlash = (unsigned int*)ADDR_FLASH;
flashValue = (*pFlash);

Like Igor and Jonatan said, reading from the Flash is as simple as reading
from a memory location. However, writing to flash is a bit complicated. If
you are looking for a simple command to write to a particular location, you
should know that that is not possible.

Read the above mentioned Application Note and also refer to this old thread
and that might give you some ideas.
