#org error
PostPosted: Mon Mar 27, 2006 8:11 am     Reply with quote
PIC18F8680 MPLAB 7.31 CCS 3.241

I created my own PIC18F8680 (PIC18F8680MEM) with extended memoru ap to 512288 program words.

I have a bootloader running in the internal memory of PIC and it is supposed to program the real app code to the external Flash program memory. External memory begins at 0x10000 and goes up to 0x80000 (19bits of address - 512kwords). The configuration I want is EMCU extended microcontroller mode, with internal and external program memories.

The problem is when I write the real code (that is supposed to begin at 0x10000) with #org directive.

Ok if I include only the #org 0x10000. If I try to include other #org´s the error appears again.

Code:
 
#include "18F8680MEM.h"
#device *=16 ADC=10
#fuses HS,NOWDT,NOPUT,NOPROTECT,BROWNOUT,NOLVP,NOCPD,NOWRT,EMCU#use delay(clock=20000000)
#use rs232(stream=RS232,baud=9600,xmit=PIN_C6,rcv=PIN_C7,parity=N,bits=8)
#case
#build(memory=0x10000:0x80000)

#define BASE 0x010000
#define BUZZER            PIN_C2
#define LigaBuzzer()      output_high(BUZZER)
#define DesligaBuzzer()      output_low(BUZZER)

#org 0x010000
void main(void)
{
   while(1)
   {   LigaBuzzer();
      delay_ms(150);
      DesligaBuzzer();
      delay_ms(50);       
   }
}

#org 0x010500,0x10600
void timer0(void)
{
}

#org 0x010700,0x010800
void timer2(void)
{
}


The error is

#build, puts the reset vector (start of the PIC code), at 0x10000. You can't then put main at the same spot (and in fact don't need to). The compiler will automatically put the 'code' into the area defined by 'build', with a jump to the 'main' at this point. If you define main far enough into memory to make room for the jump, it should compile without complaint.

Best Wishes
