    Hi Saneesh,

    Assuming you're using uVision you can right-click on a file in your project, select "Options for file..." and select the RAM region configured for your project in the "Code/const" dropdown. The scatter load mechanism should take care of everything for you.

    You can also hand-edit the scatter load (*.sct) file to achieve the same thing. Read up on scatter loading in the ARM documentation.

    Keil has an example for this approach here, assuming you have Keil installed in C:\Keil:

    C:\Keil\ARM\Examples\RAM_Function
