HELP!!!
Can ANYBODY read fuse settings for Atmega8 with PoyProg and post the PICTURE??
Please...
Your question is a bit vague.
What Atmega8 do you need the fuse settings for? Is it an official Arduino board. Does it run at 3.3V or 5V? Is it using 16MHz crystal or 8MHz internal oscillator.
There is a nice online fuse calculator here
Looking at my boards.txt file and a 16MHz AtMega8 uses.
atmega8.bootloader.low_fuses=0xdf
atmega8.bootloader.high_fuses=0xca
Hi !
I Make SingleSided (v3) with serial communucation (5V), make board working (almost), burn bootloader (atmega8.hex), burn fuses, upload Blink sketch ( working nicely ), but when I upload another sketch got message: avrdude: stk500_getsync(): not in sync: resp=0x00
I assume there is problem with fuses (particulary lock bits)...
As programer I use Ponyprog (freeware), I am not good "with command line" software like Avrdude...
Need printscreen fusebit settings.
Forgot 16MHz...

I'm no good with command line AVRdude switches etc. either.
Are you using PonyProg to just burn bootloaders or are you also using it to burn programs?
I don't have a spare ATmega8 to read from at home + they will be set to internal oscillator anyway.
The boards text for ATmega8 show
atmega8.bootloader.unlock_bits=0x3F
atmega8.bootloader.lock_bits=0x0F
If that helps.
No...
With Ponyprog burn ONLY the bootloader, for programming I use the Arduino, first sketch work but another or even the same none.
The Ponyprog fuse section do not have possibility to input Hex, just switches:
wdton
ckopt
eesave
bootsz1
bootsz0
bootrst
bodelevel
boden
sut1
sut0
cksel3
cksel2
cksel1
cksel0
and lock bits:
BootLock12
BootLock11
BootLock02
BootLock01
Lock2
Lock1
I am not shure what I wont to select
Okay, if you go to the the fuse calculator link I supplied in my first reply you can enter the fuse values and it then shows the relevant bits. Not sure about lock bit calculator though.
Thanks for your replay
I'll try your combination (even I try it before) with same result, one time upload working fine, then Avrdude reject me...
Except your link for fuse calculator, I found another one that account and lock bits, I'll try, and we see the result...
