Hi, I would like to know if someone used the bootloader from Microchip AN851 but with CCS? I am very interested in doing it.

Use the forum's search page to search for AN851. Then you'll see all
of our previous comments on that Appnote. Here's the link:

Hi,
I had downloaded the AN851, I modified the file AMS for use with the PIC18f452, I had programed the pic with the bootload.hex using another programmer, now I can connect to the PIC18QP.exe, I can program my application using this bootloader, I can even read the memory, apparently everything is OK, but the problem is that when I press the "Normal Execution mode" and accept, apparently the pic must go the Modo RUN, but the application does not work and I can not enter again to boot mode, unless the bootloader program again or modify the last memory address of 0x00 to 0xff, someone could help me?

Here is aplication
Code:
#include <18F452.h>

#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=19200, xmit=PIN_C6, rcv=PIN_C7,RESTART_WDT,ERRORS)

#define LEDV    PIN_D0
#define LEDR    PIN_D1
#define LED_ON  output_high
#define LED_OFF output_low

#define VECTOR_RESET 0x200
#define VECTOR_INTERRUP 0x208
#build(reset=VECTOR_RESET, interrupt=VECTOR_INTERRUP)
#org 0x00, 0x1FF {} // Protejer este espacio
                     Necessary for Bootloader

void main()
{
   LED_OFF (LEDV);
   write_eeprom(255,"ff");
   Delay_ms(500);

while (TRUE){

           LED_ON (LEDV);
         Delay_ms(400);
   
            LED_OFF (LEDV);
            Delay_ms(400);
            
      }   
}
