Using printf with CW8.2.3

Gibson — Fri, 07 Aug 2009 22:08:17 GMT

Hi,

I'm begining a new projet with the MC56F8002 and CW8.2.3 SE (on XP and programming with an USB TAP). I want to dump some data in a console window using printf but I have some linker error. I made a search on this forum's section for printf, but find noting to help me.

This is my simple code:

#include "Cpu.h"

#include "Events.h"

#include "stdio.h"

#include "PE_Types.h"

#include "PE_Error.h"

#include "PE_Const.h"

#include "IO_Map.h"

void main(void)

{

PE_low_level_init();

printf("Hello\n");

for(; {}

}

Now, when I try to compile it, I get this error:

Link Error : Segment overflow: .p_Code

Reserved size is 0x00001e68 -- Overflow 0x00001ba4

Link Error : Segment overflow: .x_Data

Reserved size is 0x000007fe -- Overflow 0x000005b0

Link failed

I think it must be a simple memory configuration problem but I have no clue how and where to fix it,

Need some help!

Thanks

Gibson

Hi,

I checked in the examples delivered on the installation.

It seems we don't recommend to use printf function (too large for this chip).

On the example we used another function named __ConsoleWrite(...).

Please see attached

printf_example.zip using __ConsoleWrite(...)

Another interresting example.

Please refer to your installation under:

\CodeWarrior for DSC56800E v8.2.3\(CodeWarrior_Examples)\DSP56800x_hostIO\projects

Hope this will help you.

Regards

Pascal
