| #import not working [SOLVED] |

If I do #import(FILE=bootloader.hex,HEX) in my application code, bootloader works fine but the application does not load.
Doing #import(FILE=application.hex,HEX) in my boot-loader works fine.
(But I don't want this, because I would have to compile my project twice every time)
Also burning just the application code without the bootloader ( but including the header) does not work. It used to work for my PIC18 controller.
What seems to be the problem here. Any help?
PIC: PIC24EP512GU810
Compiler: v5.015

I'd try restricting the load range, to the area where the actual bootloader lives.
Problem is that the bootloader, contains a 'dummy' application, doing nothing, sitting where the main application is meant to be. This overwrites the first few bytes of your main application...
If you look at 'ex_pcd_booloader.c', this is the bit:
| Code: |
#org LOADER_END+1,LOADER_END+5
void application(void)
{
while(TRUE);
}
|
This has to exist, but if you 'import' this, over the main code, it'll stop things working.
So use the 'RANGE=start:stop' option in the import, using the bottom of memory up to 'loader_end' as the range to import. |

Thanks!
For those with similar problem.
I was using ccs example bootloader. I calculated LOADER_END from "PCD_Bootloader.h".
And changed the #import to
| Code: | | #import(FILE=loader.hex,HEX,RANGE=0:4095) |
Where LOADER_END=4095 |
