Hi all,
I am working on lpc 11u14 uc.You might be knowing there is no inbuilt EEPROM inside it.So,I would have to use flash memry to store data.

Does any one know,How to store configuration data in internal flash and how to
perform read/write and erase operation on the same.

waiting for your reply at earliest.

Hi,
Thanks for the reply
I have tried and It works fine as i am using lpc 1227 and there is Flash information Block in it.I am able to read write to the location but my question is,In lpc 11u14 this flash action is not available so I will have to break 32 KB flash into two section,One for program and 1 for data storage.

I have tried this by making changes in mem.ld file but Its not working,what could be the problem.Do i need to write ld file for this new section too.if yes then what?
