After some time, I discovered gplink option "-f VALUE". How didn't I see it
before??
It just does what I needed in a much simpler fashion.
sdcc -mpic16 -p18f4550 "-Wl -f 0x" file.c
That generates a .hex file with unused program memory filled with 0x.
Just in case it is useful for somebod
I don't need fuses in the file because fuses are determined but bootloader
and you can't change them later.
Fuses are out of the 32K region. That's why I added them because without
padding, I couldn't get the full 32K. Adding fuses, which are out of that
range, allowed dd to copy 32K.
Exactly, con

How many bytes is "fuses"? Is it pretty constant? Is "fuses" part of the 32K?
If "fuses" is constant, you could append it binary file before feeding back to
'objcopy' to make the intel hex file.
E.g. 'fuses.bin' are the last one byte of your download.
% dd if=file.bin of=t1.bin
Thanks a lot for your help
Finally this is what I did:
$ objcopy -I ihex -O binary file.hex file.bin
$ dd if=file.bin of=file_full_range.bin count=1 bs=32768 (18f2550
memory size in bytes)
$ objcopy -I binary -O ihex file_full_range.bin

Hi!
I want to use a bootloader (Scene Double bootloader) for PIC16 and it
requires to export the full program memory range of your application (even
unused range), with no eeprom nor fuses.
This is the exact text present in the bootloader manual:
