Hi All,

I'm trying out IAR's embedded workbench version 3.2A for the first time 
and I've stumbled upon some questions which i hope you can help me with.

1)
when you write:

printf("Hello World");

It seems (or so i think) that IAR stores the string in RAM rather
than 
in flash why is this and how can it be changed ?


2)
How do you store variables in flash ?

writing: 

const char buffer[]="Hello World";   // is this stored in flash ?
__flash char buffer[]="Hello World"; // this is stored in flash


3)
If I make a long (1024 bytes) string (array) in flash:

__flash char string[1024]={...alot of data...};

And I want to print this to the serial port I do this:

printf("\r\n%s",string);

But it does not work...

So I though I needed a pointer to it... 


__flash char string[1024]={...alot of data...};
char __flash *ptr;

ptr=&string[0];
printf("\r\n%s",ptr);

This didn't work either !?

4)
It seems that in the manual there's a function called:

printf_P for printing from flash but which file must I include to use 
this printf function ? I cant seem to find it?

Best Regards
Lasse Madsen
