How to add microcontrollers to avrdude?

i want to set fusebits of atmega48pa mcu but avrdude has option only for atmega48 variant???

The latest version of AVRDUDE (7.0) does support the ATmega48PA. Here are the lines in avrdude.conf that define it:

#------------------------------------------------------------
# ATmega48PA
#------------------------------------------------------------

part parent "m48"
    id               = "m48pa";
    desc             = "ATmega48PA";
    signature        = 0x1e 0x92 0x0a;
  ;

If you can’t install the latest version for some reason, you might try adding those lines to your avrdude.conf file. Or you could tell AVRDUDE you are using an ATmega48 and add the -F option to make it ignore the signature mismatch.

i have now bigger problem with avrdude…
i downloaded latest version (avrdude -v7.1-windows-x64)
tried to open .exe file to install and nothing happens.
then i tried x86, and nothing,
after that i tried version (7.0), both x64 and x86, and they wont do anything either…

i tried to uninstall old version and then open .exe file of every version i downloaded and still nothing happens,

now i dont have any avrdude installed and cant install new :frowning:

and by nothing i mean that when i open .exe file it only flashes some window for split second, so fast i cant even read what it opens.

i downloaded avrdudes from here Releases · mariusgreuel/avrdude · GitHub

edit:
i managed to get it working but, now i get this in commandpromt:
C:\Users\nokia>avrdude -P com5 -b 19200 -c arduinoisp -p m48pa -v
