I am using an arduino uno as ISP with pins 10,11,12,13 respectively rest,mosi, miso, sck. I have a 22uF capacitor on the arduino board hooked between gnd and reset pins. I keep getting a "invalid signature", tried with protocol = arduino and with protocol = stk500. with high fuse = c4 (if I chzange it to c2 I get another message, like it's not communicating with the target). Does the provided atmega8_noxtal loader work with the atmega8-16pu? Hello, I am trying to load the bootloader on an atmega8-16pu, but I keep getting a “wrong signature” message.

Can I use the same setup as you have shown for this chip. I want to stick to the factory default clock settings. Should I be able to do this. Thank you for any advise ... VR Hi,
I just ordered a atmega168A-PU chip from protostack. Can I use the same setup as you have shown for this chip. I want to stick to the factory default clock settings. Should I be able to do this.

In boards.txt, I had to change: atmega8noxtal.upload.protocol=stk500 Into: atmega8noxtal.upload.protocol=arduino And now it works :) I had a problem with this, some error about a device signature that couldn’t be read (don’t remember it exactly).

And now it works :)

The only way I can get this to work is if I burn the bootloader with an STK500, then connect up my FTDI cable to the chip (while power is supplied by the STK500). At this point I can program the chip through the Arduino IDE, but the weird thing is that I can only do this 1 time after burning the bootloader. Any other time I get "avrdude: stk500_recv(): programmer is not responding" from the Arduino IDE. I don't understand how it works the first time, but not the second. My test is to burn the "Blink" example. The first time I do it, I change the delays to 500 so I can tell that it has worked. The second time I try using 2500 on both delays. When this won't work, I burn the bootloader again and then (without changing anything on the arduino IDE, leaving the delays at 2500) it burns correctly. I have even tried just burning the exact same sketch twice to no avail. I am using Atmega238P-PU chips. This is driving me nuts. I'm pulling my hair out, what am I doing wrong?

This is means that I turn OFF Arduino, after I push UPLOAD button and turn ON my Arduino ^^ Sorry for language, I am russian ^^ Tangle,
