Local variables storage optimization

Hi ,

I am using ARM Cortex M4 . When I compile my code I get "No space in Execution region with .ANY selector matching section .const data .When I decrease the code size I am able to compile the code properly.I think I am overusing the data section which in my controller is 32KB.

I want to know where are all local variables stored in ARM KEIL IDE.Is it stored in Stack dynamically or stored in DATA memory Statically .

Thanks in advance

Regards,
Dhanush
