| Yet Another Bootloader Question |

Hi All,
After getting the bootloader working, my application is quite large and takes too long to load via the bootloader, but will be perfect when the board is in use.
So, my question is can you load the bootloader and application together, via the ICD. |

Yes.
There are various ways of building the file needed. Honestly the simplest, is to use MPLAB (one of the older versions preferably), then load the bootloader hex file, and then the program hex file, and export the result.
Other method needs a little fiddling.
Build the bootloader, with #fuses=none
Ensure the clock setting matches your real fuses.
Then #import the bootloader into the application. Line needed should be:
| Code: |
#IMPORT (FILE=yourbootloader.hex,HEX,RANGE=0:LOADER_SIZE) |
The application needs the correct fuses and clock settings before this.
Now using #fuses=none, prevents the compiler from complaining when the fuses import (though you are specifying not to import this range, it still does so...).
The resulting output file from compiling the application like this, will include the bootloader.  |
