Trying to bootload atmega 8 (lock fuse error)

Hi,

I spent all night trying to fix this problem.

I`m trying to bootload an arduino(atmega8) with the parallel programmer(http://www.arduino.cc/en/Hacking/ParallelProgrammer). Using the command line + avrdude

I`m using these tutorials:

  1. https://web.archive.org/web/20200610013744/http://www.uchobby.com/index.php/2007/09/12/how-to-update-the-arduino/
  2. Arduino on a prototype board – tinkerlog

The first one doesnt start with setting the fuses.
avrdude -c dapa -i 800 -p m8 -U flash:w:ATmegaBOOT.hex

This starts bootloading directly. But whet its finished led 13 doesnt do anything. And i cant upload sketches using serial.

I hope that that`s beacause of the fuses needed to be set.

That`s described in tutorial 2.
avrdude -v -c dapa -p ATmega8 -C avrdude.conf -U hfuse:w:0xCA:m -U lfuse:w:0xDF:m -U lock:w:0xFF:m

But this gives me an error:

C:\Arduino IDE\hardware\tools\avr\bin>avrdude -v -c dapa -p ATmega8 -C avrdude.c
onf -U hfuse:w:0xCA:m -U lfuse:w:0xDF:m -U lock:w:0xFF:m

avrdude done.  Thank you.

So it fails at the lock fuse. I can`t figure out how to fix it...

I hope someone here spots the problem.

Thanks in advance!!

Noone?

Ok, i think i now have programmed the chip correctly.

I used these commands:
avrdude -c dapa -p m8 -e -F -u -U lock:w:0x3f:m -U hfuse:w:0xca:m -U lfuse:w:0xdf:m

avrdude -c dapa -p m8 -U flash:w:ATmegaBOOT.hex -U lock:w:0x0f:m

For the first time i didnt see any errors.

So does that give a guarenty the chip is loaden correctly?

When i press reset afterwards led 13 does not blink :frowning:
