KE04Z8 TX Problem

Hey ,

I using the MKE04Z8 device on my pcb , my problem is that I can't see anything in the line.

I configure the PTA2 as RX PTA3 as TX and used the next basic code:


/* Write your local variable definition here */

  byte packet[2]={100,100};

  word sent ;

  byte retval;

  /*** Processor Expert internal initialization. DON'T REMOVE THIS CODE!!! ***/


  /*** End of Processor Expert internal initialization.                    ***/



  /* Write your code here */

  /* For example: for(;;) { } */






what I done:

1. I configured the next code on PTB0 and PTB1 and it send data.

2. I took the pin of the PTA3 and disconnected it from the pcb and still no output signal.

3. I tried the code on the FRDM and it worked.

4. I tried it on more then 1 PCB Board with different devices.

5. I work on eclipse code warrior and I tried it on kinetis design studio and still not working.


I think that is something on the pin(PTA3) configuration , Any suggestions ?

BTW, The RX line works perfectly and I am attaching picture of the codewarrior window
