Can't print on the monitor

[SanderDijkstra]

Hi all,

For days i've been trying to print something on my monitor, but without succes.

I use the MC9S12DP512 (CardHCS12) which has the Twinpeeks monitor on it. Thereby I use the OC-console and CodeWarrior.

The following example works in the Simulator and I can load it into the HCS12 with OC-console (after using sreccvt and updating the .prm-file to prevent "invalid bank load address errors" ).

When I run the prog, the HCS12 responds (I assume, because the default led stops) but doesn't show anyting on the OC-console.

--example from CW Help System: "Library: printf support"---

#include "Cpu.h"
#include "PE_Types.h"
#include "PE_Error.h"
#include "PE_Const.h"
#include "IO_Map.h"
#include <stdio.h>
#include <termio.h>

void main(void)
{
 /*** Processor Expert internal initialization. DON'T REMOVE THIS CODE!!! ***/
 PE_low_level_init();
 /*** End of Processor Expert internal initialization.                    ***/

 TERMIO_Init();
 for (; {
   (void)printf("Hello %s\n", "World");
 }

 /*** Processor Expert end of main routine. DON'T MODIFY THIS CODE!!! ***/
 for(;{}

(I also tried the Guess the Number-tutorial without succes)

Can somebody give me a hint how to get printf working?? 

Thank a lot,

Hello

How are you communicating with the board?

Are you using a P&E Multilink cable, a Softec InDart Cable, ....?

Where do you expect to see the output for printf?

Hi!

I'm using the OC-console terminal and the the board is connected with SCI 0 to my COM-port (serial cable).

I want to see the output on the terminal; so I can use printf to check a program when it is running.

Hello

Normally printf is using the low level function TERMIO_PutChar to send characters to stdout.

Also It is good practice to call first TERMIO_Init to initialize the SCI port.

Can you check if you call the function TERMIO_Init prior to the first printf?

Can you also check if the low level functions TERMIO_PutChar and TERMIO_Init you are linking with your application are appropriate for setting up and writing to SCI0?

Hello,

To get info on how to use PRINTF, look for printf in the search engine.
