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
Your text strings always (!) needs to be stored in the flash. Nothing but what you have in flash survives a power cycle.
Copying the text strings into a RAM variable will not remove the use of flash. It will just add extra code to do the copying. Any copying still requires a source.
Switching to the microlib means you get a bit smaller library so there is a bit more code space available for your own program.
In the end, your program is too large for the processor or for the Keil license.
