Problem running a flashed code on ATmega8

Using Arduino Installation & Troubleshooting
#1

Good morning from Munich, Germany!

I have an application which runs perfectly on a ATmega168 when downloaded via the Arduino IDE.
After successful compilation / linking for ATmega8, I have flashed it on a chip.

BUT, while the
** **setup()** **
starts to execute, it seems to hang in a
** **delay(5000);** **
call:

void setup() 
{
  int i;

  lcd.begin(lcdNUM_COLS,lcdNUM_ROWS);
  lcd.setCursor(0,0);
  lcd.print(" WWCC - (c)PRMD ");
  lcd.setCursor(0,1);
  lcd.print("Version: JUN2011");

  // 
  // Declare the digital I/O pins
  //
  pinMode(...);

  //
  // Wait until TS have settled 
  // 
  delay(5000);
  
  //
  // Read ADC channels 2-5 for setting the timers and temp thresholds
  //
  wwccTune(FALSE);

  delay(5000);

  // Read temperature sensors
  sensorOld0 = analogRead(wwccTS0_PIN);
  sensorSum0 = wwccNUM_SAMP * sensorOld0;

  sensorIdx  = 0;
  for (i=0;i<wwccBUF_LEN;i++)
    {
    sensorAdc0[i] = sensorOld0;
    }
}

The function wwccTune() is expected to perform some lcd.print() calls:

void wwccTune ( boolean t ) 
{
  if (t)
    {
    // Read ADC channels 
    }
  else
    {
    // Preset ADC values with constants
    }
    
  lcd.setCursor(0,0);
  flt2strC(pLcdLineL,adc2deg(coldTemp));
  *pLcdLineL = 'C';
  lcd.print(pLcdLineL);
}

Do you know of any restriction for the ATmega8 wrt ATmega168?
The LCD works fine (at least I have my welcome banner properly displayed).

Here is the flash programming output from avrdude:

avrdude done.  Thank you.

Any hint would be most appreciated …! :wink:

#2 
*pLcdLineL = 'C';

Was the pointer properly initialized? Almost seems like there was a memory leak somewhere...

Well, the code has been running correctly on various platforms w/o any problem. I do trust the code I wrote and tested. I should then have written ``` lcdLine[0] = 'C'; ``` for the sake of clarity, since I have not provided the whole code. Where the declaration is global to the application [b]char lcdLine[17];[/b] The point is that the code is running correctly on a ATmega168 chip (code downloaded via Arduino IDE) but not on a ATmega8 chip (code burned in flash via avrdude since no bootloader). So I was just wondering whether there were known restictions/limitations between the 2 chips, and/or the way they are programmed. Any hint / suggestion is welcome and most appreciated. Thanks I
