[En-Nut-Discussion] Thread Switching Problem

[Ralph Mason]

I guess it’s a problem in your TCPservice function.

Subject: [En-Nut-Discussion] Thread Switching Problem

I have the following code and my thread is not switching from main() to
Compute() Thread except for the first time. All threads have same priority.
Service thread is a TCP reuest Thread.
  THanks for help in advance

  THREAD(service_thread, arg)
{
 //NutThreadSetPriority(61);
      for (;;)
 { 
        PORTD = PORTD & 0xfe;
  //DDRD = 0xff;
  //PORTD = 0x00;  
    TCPservice();
  
  PORTD = PORTD | 0x01;
  //DDRD = 0xff;
  //PORTD = 0xff;
 }
}
  THREAD(compute_thread, arg)
{
 //NutThreadSetPriority(65);
    for (;;)
 {
  NutSleep(500);
        PORTD = PORTD & 0xfd;
  NutSleep(500);
  PORTD = PORTD | 0x02;
  //DDRD = 0xff;
  //PORTD = 0x0f;
  //NutSleep(1000);
 }
}
