The procedure for the bootloader is always the same:
1) Get a program running properly in your chip _without_ the bootloader.
Make sure it can talk to your serial port, detect the pin you are going to use to trigger the bootloader, and runs at the correct rate.
2) Then record the fuse/UART settings for this, and copy these into the bootloader file. Use these fuses for the bootloader, and and code you are going to bootload. So replace (for example), the section:
| Code: |
#elif defined(__PCH__)
*#include <18F45K22.h>
#fuses NOWDT
#use delay(crystal=16MHz)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)
#endif
|
In the ex_bootloader.c file, with the one for your chip. Say (for your chip at 20Mhz):
| Code: |
#elif defined(__PCH__)
#include <18F6310.h>
#fuses HS,BROWNOUT, BORV43,STVREN,NOMCLR,STVREN,NOMCLR
#device ADC=10
#use delay(crystal=20000000)
#use rs232(UART1,ERRORS,baud=9600)
#define PUSH_BUTTON PIN_A4
#endif
|
Save this as (perhaps) 'yourbootloader.c', and compile this
Then use ex_bootload.c, as the sample for your 'loadable' program, again replacing the processor/fuses with a duplicate of these, and adding your main code.
The bootloader _always_ needs to be customised to match _your_ hardware. |

Here is the modification that I did
on EX_BOOTLOADER.C
but I get "A #DEVICE required before this line" error
what couldn't the the problem
*I did successfully compilation with the original EX_BOOTLOADER.C
cheers
| 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 <18F6310.h>
//#fuses HS,NOWDT,NOPROTECT,NOLVP
#FUSES NOWDT,INTRC_IO,NOBROWNOUT,PUT,NOSTVREN,NODEBUG,NOFCMEN,NOXINST,NOPROTECT,NOLPT1OSC,NOMCLR
#use delay(clock=16000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7) // Jumpers: 8 to 11, 7 to 12
#endif |

| Missing # on the first line. So it sees it as a 'if' (code instruction), not as '#if' (pre-processor instruction). Code can't run without knowing the processor.... |

here the complete file
but still
#DEVICE required before this line
error
| Code: | ///////////////////////////////////////////////////////////////////////////
//// EX_BOOTLOADER.C ////
to_isr(LOADER_END+5*(getenv("BITS_PER_INSTRUCTION")/8));
|

Bootloader code removed.

You are not possibly compiling in MPLAB?.
You would see this error if one or more of the files bootloader.h, or loader.c had been included in the project files. |

Scanan,
I assume your signature is intended to be ironic?

It's spelt professional!! My spelling OCD kicking in ;-)
And for correct grammar, change it to the following
