I'm trying to burn the bootloader and I can't find the fuse bits for the atmega328p. I'm using the bitbang method.

Hi,

you find the fusebits for every chip supported by the Arduino in the "boards.txt" file that is installed along with the Arduino-application in the hardware-directory

Thank you, Seth! I tried this method and it worked great, but I cannot read eeprom memory. All other memories I get, but -U eeprom:r:eeprom.bin:r don't work correctly. Avrdude was reading eeprom and told that it saves content to file, but file is empty - length 0. I tried to write some symbols to that file and send to eeprom - it worked and my symbols stored. I tried to read eeprom from terminal mode - all is ok - I see my symbols stored. I suppose that problem is not in file type (.bin, .eep, or another) and problem is not in type specified after filename - r, i or another. All these I tried and nothing happens. Except - when read eeprom with i type, I get file of length 13 and it contains string - :00000001FF

What I do wrong? With another avrdude, which compiled for working with emulated COM port, I read eeprom with the same parameters.
