Hi, I did something similar last week, no problems, what compile line you use?
Attached please find my sample code that blinks a LED and prints
"hello, world" through
UART port. Also attached is the Makefile, which should show you a
command line/options
that I used to compile this and make it work.

Hi!
I'm trying to use SDCC compiler to build firmware for Microchip
micro-controllers. I'm currently using PIC 18F4550.
I'm using piklab IDE to compile C source code and to program the chip
using ICD2 hardware.
I made a simply (and sample code) to test the SDCC compiler
integration
in Piklab IDE software, I'm working in Linux environment (Ubuntu);
although the hex file is created resulting from compilation, when I
program the chip nothing happens - the PIC 18F4550 does nothing!
The C code is:
/******************************************************************/
/*
*/
/* C code for PIC18F4550 that configures PORTA pins as outputs and
*/
/* puts high level on them
*/
/******************************************************************/
#include <pic18f4550.h>
#include <signal.h>
#include <pic18fregs.h>
#include <stdio.h>
#include "PIC18test.h"
code char at __CONFIG1H CONFIG1H = 0x01;
// _OSC_XT_1H & _FCMEN_OFF_1H & _IESO_OFF_1H;
void main(void)
{
// make all pins of port A as outputs
TRISA = 0;
// Configure LCD_PORT if in use
TRISB = 0;
// Configure LCD control pins
TRISD = 0xF7;
// Put all PORTA outputs to high
PORTA = 0xff;
}
There's anything wrong in compilation? Can anyone help me?
