avrdude and atmega48pa

Can i programm the atmega48pa with avrdude? I have problems with the signature ...

% avrdude -pm48 -cavrisp2 -Pusb -V -U flash:w:main.hex

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.01s

avrdude: Device signature = 0x1e920a
avrdude: Expected signature for ATMEGA48 is 1E 92 05
         Double check chip, or use -F to override this check.

avrdude done.  Thank you.

I have add some new lines to the avrdude.conf in /etc -directory

[...]
part
    id               = "m48pa";
    desc             = "ATMEGA48PA";
     has_debugwire = yes;
     flash_instr   = 0xB6, 0x01, 0x11;
     eeprom_instr  = 0xBD, 0xF2, 0xBD, 0xE1, 0xBB, 0xCF, 0xB4, 0x00,
                     0xBE, 0x01, 0xB6, 0x01, 0xBC, 0x00, 0xBB, 0xBF,
                     0x99, 0xF9, 0xBB, 0xAF;
    stk500_devcode   = 0x59;
    signature        = 0x1e 0x92 0x0a;
[...]

but now i get a another error

avrdude: safemode: Verify error - unable to read lfuse properly. Programmer may not be reliable.

Edit - 1

Here some debugging information with "-vvv":

% avrdude -pm48pa -cavrisp2 -Pusb -F -vvv -U flash:w:main.hex

For reference, here's a link to your question on electronics.stackexchange.com (with answer) https://electronics.stackexchange.com/questions/3721/avrdude-and-atmega48pa

Basically, as you've shown you can add the chip config to /etc/avrdude.conf - and in fact, in your final example it works correctly.

Just use the -F option to over ride the check. It programmes without any problems for me. It is not the most elegant solution but is better than not being able to run your program.
