| Bootloader example don't compile |

Hello!
I'm trying to create bootloader by modifying the example provided by CCS but I get an error at one of the loader.c lines.
Here is the code I made:
| Code: |
#include <16F873A.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=16000000)
#use rs232(baud=9600, xmit=PIN_C2, rcv=PIN_C3,ERRORS)
#include <bootloader.h>
#include <loader.c>
#org LOADER_END+1,LOADER_END+10
void application(void) {
while(TRUE);
}
#org 0x20,0x3F
void main(void) {
if(!input(PIN_B5))
{
load_program();
}
application();
}
#ORG default
#int_global
void isr(void) {
jump_to_isr(LOADER_END+5*(getenv("BITS_PER_INSTRUCTION")/8));
}
|
The line of the error is
| Code: | | #ORG LOADER_ADDR+10, LOADER_END auto=0 default |
(this line is in loader.c the driver I have inserted)
The error I get is : Invalid ORG range
Where I'm wrong?

| Have you actually got the examples supplied by CCS to compiler and execute correctly? |

| You have 2 #org statements that have overlapping addresses. You can see that by comparing the #org in your code with the one in the error line. You should probably take a step back and really make sure you know where things go. From my own experience, a large % of bootloader problems come from stuff not placed in the right address locations. |

Thank you guys!
I saw my mistake was not using complete example bootloader.c
Now the code compiles fine!
New bootloader code is:
| Code: |
#include <16F873A.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=16M)
#use rs232(baud=9600, xmit=PIN_C2, rcv=PIN_C3,ERRORS)
#define _bootloader
#include <bootloader.h>
#include <loader.c>
#org LOADER_END+1,LOADER_END+10
void application(void) {
while(TRUE);
}
#org 0x20,0x3F
void main(void) {
if(!input(PIN_B5))
{
printf("Ready...");
load_program();
}
application();
}
#ORG default
#int_global
void isr(void) {
jump_to_isr(LOADER_END+5*(getenv("BITS_PER_INSTRUCTION")/8));
}
|
The code to send:
| Code: |
#include <16F873A.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=16M)
#use rs232(baud=9600, xmit=PIN_C2, rcv=PIN_C3,ERRORS)
#include <bootloader.h>
void main(void)
{
char c;
delay_ms(100);
while (true)
{
c = getc();
putc(c);
}
} |
How to send my second code. I guess I need special software for my PC.
I tried to use this one http://www.etc.ugal.ro/cchiculita/software/picbootloader.htm
but it can't establish communication with my PIC. Apparently I need another software.
I have heard that I can use hyperterminal, or Serial Input/Output Monitor(siow provided by CCS), but I don't know how to load the hex file to be send.
Thank you in advance!
