| Bootloader example code compile error |
 Posted: Tue Jun 01, 2010 3:08 am |

Hi all,
I create a project simply with CCS example codes as below,
bootloader.h
ex_bootloader.c
loader.c
18F452.h
One error comes out:
"*** Error 128 "loader.c" Line 42(1,4): A #DEVICE required before this line"
Part of the code, shows where the error happens,
"
#define LOADER_ADDR LOADER_END-LOADER_SIZE
#define BUFFER_LEN_LOD 64
int buffidx;
char buffer[BUFFER_LEN_LOD];
#define ACKLOD 0x06
#define XON 0x11
#define XOFF 0x13
"
So why the compilation fail?
Actually i have no idea of the layout the bootloader example code. 
And i want to put a bootloader code in the upper flash memory, but in trouble of using the "ORG"...
Thanks in advance. |

You need to tell the compiler information about which PIC chip you plan to use. You need a line like:
#include <18F2685.h>
Substitute the proper header for your chip. |

Thanks ckielstra, collink,
Previous at the head of ex_bootloader.C, where the main located.
| Code: |
if defined(__PCM__)
#include <16F877.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7) // Jumpers: 8 to 11, 7 to 12
#elif defined(__PCH__)
#include <18F452.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7) // Jumpers: 8 to 11, 7 to 12
#endif
|
I use a simple "#include <18F452.h>" to replace the above code.
The error " A #DEVICE required before this line" disappear.
Then include some related head files,
<stdio.h>, <stddef.h>, <string.h>,<ctype.h>.
I come with the error as below,
--------------------------------------------------------
Executing: "C:\Program Files\PICC\Ccsc.exe" +FH "ex_bootloader.c" +EXPORT +DF +LN +T +A +M +Z +Y=9 +EA

Note that I make this project with below CCS example source files:
bootloader.h, ex_bootloader.c , loader.c
Thanks,

Are you using MPLAB ? If so, there should be only one file listed in the
Project Window under Source files. It should be the Ex_Bootloader.c file.
I made a new project in the c:\Program Files\Picc\Examples directory
using the MPLAB Project Wizard. I gave the project the name of
Ex_Bootloader. I set up the project to use the 18F452. Then I added
the Ex_Bootloader.c file to the project and compiled it by clicking the
"Build All" button in MPLAB. It compiled with no errors.
The key point is that you should not "add" to the project all the various
files in your list above. Only the Ex_Bootloader.c file should be "added"
to the MPLAB project. If you have other files in the Source Files list in
MPLAB, then remove them. |

Hi PCM programmer ,
Yes, I am using the MPLAB V8.50. CCS PCH V4.049
I have fully followed your procedure.
The compile error this time is,
"*** Error 18 "ex_bootloader.c" Line 41(10,20): File can not be opened"
It shows that #include <18F452.h> can not be open...
Actually I am used to assembly language, not good at C at all.
BTW, I was confused with #org. I read your post as below, it does help. Thanks.

I made the following program, based on your description, and it
compiles without error with PCH vs. 3.241.
Code:
#include <18F452.H>
#fuses XT,NOWDT,NOPROTECT,BROWNOUT,PUT,NOLVP
#use delay (clock=4000000)
#build (reset = 0x0002)
#rom 0x0000 = {0x0000}
#org 0x7F00, 0x7FFF
void my_function(void)
{
char c;
c = 0x55;
}
//==================================
void main()
{
my_function();
while(1);
} |

Is this your first project with CCS ? Have you ever successfully compiled
a program before ? Do you have the PCH compiler installed ? Are you
using MPLAB as the IDE for the CCS compiler ? Have you installed the
CCS "plugin" program for MPLAB ? |

Hi PCM programmer,
Confirmed that my PCH compiler is not installed well. Thanks. |
