Problem with using Microchip hid bootloader with CCS
PostPosted: Sat Mar 09, 2013 5:28 pm     Reply with quote
hi.

I'm a noob trying to start learning a bit about pic's. I tried a few examples and they work fine but for more easy, fast try and learn, I installed the Microchip HID Bootloader. After that I can't get the code to work.
PIC entry in bootloader mode is ok, and I haven't problems uploading my user code, but it never works. The same code without bootloader works fine. After all day searching and reading I am going to ask for help. (Sorry if its evident the fault).

Here is the code. What am I doing wrong? thx
Code:

#include <18f4550.h>  //archivo de cabecera
#BUILD(reset=0x800,interrupt=0x808)
#ORG 0,0x07ff {}


#fuses HSPLL,MCLR,NOWDT,NOPROTECT,NOLVP,NODEBUG,USBDIV,PLL5,CPUDIV1,NOVREGEN,NOPBADEN // fuses  configurados
// el fuse que configuramos anteriormente
#use delay(clock=48000000)     // el clock que tendremos a la entrada del CPU

void main() {

// configurando registros
    disable_interrupts(global);   // desactivando interrupciones globales
    setup_adc_ports(NO_ANALOGS);  // desactivando puertos analogicos   
    set_tris_d(0x0);              // configurando los puertos como salidas

    output_d (0);               

while(1){
      output_d (0);       // saca un nivel bajo en el portb
      delay_ms(1000);     // pause  de 1 Seg
      output_d (255);    // saca un nivel alto en el portb
      delay_ms(1000);     // pause de 1 Seg
   }
}

After another few hours of checking .... Mad

I got this code working:
Code:

#include <18f4550.h>  //archivo de cabecera
#fuses HSPLL,MCLR,NOWDT,NOPROTECT,NOLVP,NODEBUG,USBDIV,PLL5,CPUDIV1,NOVREGEN,NOPBADEN // fuses  configurados
// el fuse que configuramos anteriormente
#use delay(clock=48000000)     // el clock que tendremos a la entrada del CPU

//#BUILD(reset=0x1000,interrupt=0x1008)
//#ORG 0x000,0x07ff {}

#build(reset=0x1000,interrupt=0x1008)
#org 0x0000,0x0FFF {}
void loader(void) {}


void main() {

// configurando registros

    disable_interrupts(global);   // desactivando interrupciones globales
    setup_adc_ports(NO_ANALOGS);  // desactivando puertos analogicos   
    set_tris_d(0x0);              // configurando los puertos como salidas
   
// Programa de parpadeo

    output_d (0);                 // saca un nivel bajo de salida en los puertos

while(1){
      output_d (0);       // saca un nivel bajo en el portb
      delay_ms(3000);     // pause  de 1 Seg
      output_d (255);    // saca un nivel alto en el portb
      delay_ms(1000);     // pause de 1 Seg
   }
}

Adding in the first line of the hex file:
Code:
:020000040000FA

before upload with Microchip HID Bootloader.
