Hello everyone!
I using Olimex LPC2106-MT board and has a three questions:

1. How to determine address in flash memomry to write data?
2. Possible to read flash memomry:
unsigned int addr, data;
data = *(volatile unsigned int *)addr;
3. Possible to write flash memomry:
unsigned int addr, data;
*(volatile unsigned int *)addr = data;

Consult your memory map/section/placement file to find out what's where.

Of course - that's what the processor does to fetch instructions and
read-only data, (assuming you mean the memory-mapped flash on LPC chips).

No. Google for 'writing to flash' and search this group for 'IAP'.

Thanks a lot, Martin!

I try to write and read following code after swithed off power:

__no_init data flash_data;

flash_data++;

It work fine
