Hi all,
I had loaded the tiny bootloader on a 18f4520 but now I need to change the value of some fuses. Do The fuses i set in the program code change the fuses values programmed into the pic when I loaded the bootloader code??

Thank you very much.

Sorry for my bad english

In general whatever fuses were set when the programmed the bootloader into the PIC are it. Some of the later series PICs give you the option of setting (but not clearing) some of the configuration bits however, in general, the bootloader will not accept any commands to write to these config bit.

In summary - your application is limited to the fuses that were programmed into the PIC when the bootloader was first installed.
