[En-Nut-Discussion] Strange Ethernut board...

[Alexander Baranov]

Dear Harald.
One of my Ethernut boards behaves very strange. I wrote a simple program:

#include <sys/thread.h>

THREAD(NutMain, arg)
{
  outp(0xff,DDRD);
  while(1){
   outp(0x00,PORTD);
   outp(0xff,DDRD);
  }
}
and it does not output pulses to PORT  D.
I wrote similar program on assembler, without  NutOS, programmed the board
and saw beautiful zeroes and FF-s.
I had worked with four of such boards and encountered such an effect for the
first time. Can it be so, that there is some defect e.g. in RAM?
