Thanks Mike. I think I am going in right direction after reading your reply. This target.ld file is generated by ecos and if I am not wrong, I will need to modify the "XXXXXX.ldi" file for defining that 2K buffer in MEMORY and SECTIONS block. Well, after such define, which RAM section will act as default. Will I have to write after each and every function the __attribute__ to define its section. suppose I have two ram area defined RAM1, RAM2. which one will act as the default for other functions which are not attributed. Also, one more thing, what will be the starting address for the array defined using the __attribute__ method. Will it be the first location in that section? Thanks once again for your help.
