Hi Everyone,

I just tried to get my Coldfire 5206 to run. I want to use gcc but I 
have no experience with this compiler.
I have the bare 5206 with an Flash connected (address 0). I only want to 
count the GPIO Port.
How do I have to compile the code? When I use assembler it works, so the 
hardware should be ok.

typedef volatile unsigned char  vuint8;

#define PARAL_DIR  (*(vuint8 *)(0x40001C5))
#define PARAL_OUT  (*(vuint8 *)(0x40001C9))

void main(void)
{
  int i=0;
  PARAL_DIR=0xFF;
  while(1)
  {
    i++;
    PARAL_OUT=i;
  }
}

Greetings

Frank
