Hi,

I want to write data into internal flash where code is being executed. When i perform write operation on flash at that time i can not read or execute from flash so in this case i have to copy flash related code into RAM.

using __attribute__(("section name")) command I'd successfully mapped function into RAM but don't know how to copy that function from ROM to RAM so execution can happen. even i couldn't found ROM address for copy in .map file
 

You don't have to copy function. You just put function to RAM, linker will do all your job. For Keil you need just open file properties and specify the place where you wanna place all the functions in this file - to RAM or ROM.
