C167CS: No Output Signal on Pin P3.3 GPT1

Hi,

for a speed-controll of a single-phase DC Motor I evaluate the Infineon C167CS-LM on the EvalBoard KitCON-167 from Phytec, with two 256KB RAM and two 1MB Flash Moduls.

Working with the Hands-On Training material I used DAvE to create the code for the GPT1.

In the Startup-File Start167.A66 I changed the following registers fitting the Memory:

- BUSCON0 = 0x04AF
- BUSCON1 = 0x04AF
- ADDRSEL1 = 0x0006

The Target setup under uVison3 is the following:

- ROM 0x0 - 0x4000
- RAM 0x40000 - 0x44000 (does that work for Debugging?)
- Monitor: Phytec KC 167CR (cant find CS?!!) @COM1, 9600 Baud
- 8H-0BH, 0ACH-0AFH reserved
- (...)

The timer are initialised in gpt1.c as:
- T2/T4 as reload for T3 (depending on Toggle Latch)
- T3 in timer mode with alternate output P3.3

An connected Oscilloscope detects only noise but no pulses.

I am also wondering why all the registers of the timers and the counters itsself are displayed as "0" when I debug after a stop (peripherals menu).

This is my main.c:

#include "MAIN.H"

void MAIN_vInit(void)
{
  GPT1_vInit();
  PSW_IEN = 1;
}

void main(void)
{
  MAIN_vInit();
  while(1) {};
}

and my gpt1.c

#include "MAIN.H"

void GPT1_vInit(void)
{
  T3CON          =  0x0201;      // load timer 3 control register
  T3             =  0x0000;      // load timer 3 register

  T2CON          =  0x0025;      // load timer 2 control register
  T2             =  0xC000;      // load timer 2 register

  T4CON          =  0x0026;      // load timer 4 control register
  T4             =  0x4000;      // load timer 4 register

  P3   = (P3   & ~(uword)0x0008) | 0x0008;    //set data register
  DP3  = (DP3  & ~(uword)0x0008) | 0x0008;    //set direction register

  T3CON_T3R      =  1;           // timer 3 run bit is set
}

What could be wrong?

Thanks for any help!
