ronak,
You can also look at your map file from the compile/link.
( .map)
It will tell you how much SRAM you are using.
I doubt that you have used up all your SRAM and are having a conflict between
the IAP functions and your application.
The 2103 has 8K SRAM, how many variables have you created, how much stack have
your defined.

So, how I can make these locations free. I am using gcc compiler. Is there any
setting required to be done in the linker file. Please guide on this since i am
still not able to write into the flash memory of lpc2103.

It is mentioned in the manual that top 32
bytes of RAM should not be used by application program while using IAP command.
So, how I can make these locations free. I am using gcc compiler. Is there any
setting required to be done in the linker file. Please guide on this since i am
still not able to write into the flash memory of lpc2103.
I am using IAP command to
write into the flash of lpc2103. Is it necessary to disable all the interrupts
before calling IAP routine? If so then how i can disable and unable the
interrupts.

Yes, you need to disable all interrupts to white in flash with IAP.
To do this you must save the state of the interrupts and then restore.
Code Exemple:
unsigned long int enabled_interrupts;
enabled_interrupts = VICIntEnable; //disable all interrupts
VICIntEnClr = enabled_interrupts;

Hello All,
I am using IAP command to write into the flash of lpc2103. Is it
necessary to disable all the interrupts before calling IAP routine? If so then
how i can disable and unable the interrupts.
