[Sdcc-user] code location

[Olgierd E. <ol...@te...>]

Hi, I'm trying to locate some routines at the end of the memory for
bootloader purposes but even I want 2 or 3 rutines at the end, I don't
want all the code at the end and that's what happens when I try to do
it:

main code:
----------------------------

void rutine_ini();
void rutine();
void setup();

// Main application function for Transmittion
// should be at the begining
void main() {
	rutine_ini();
	setup();
	
} 
 
// should be at the begining
void  rutine(){

	// apagamos
	PORTHbits.RH6=0;
	PORTHbits.RH7=0;
	PORTAbits.RA1=0;
	//esperamos
	delay1ktcy(100);
	// encendemos
	PORTAbits.RA1=1;
	PORTHbits.RH7=1;
	PORTHbits.RH6=1;
	
	// esperamos
	delay1ktcy(100);
	
}	 

// should be at the END 
#pragma code setup 0x1F000
void  setup(){
	rutine();
} 
-----------
Another stupid routine in another file for test if different objects
solve the problem
-----------------------------------


#include <pic18f8722.h>
#include <delay.h>

void  rutine_ini(){

	// apagamos
	PORTHbits.RH6=0;
	PORTHbits.RH7=0;
	PORTAbits.RA1=0;
	//esperamos
	delay1ktcy(100);
	// encendemos
	PORTAbits.RA1=1;
	PORTHbits.RH7=1;
	PORTHbits.RH6=1;
	
	// esperamos
	delay1ktcy(100);
	
}

sdcc --version

All seems to be good but when I check the map I see :

As you can see, the only routine at the beginning of the code space is
the one I want at the end !!! and all the rest are at the end.

Does some friendly and experienced body can give a hand or insight ?

Thanks a lot, SDCC is a great Compiler !!
