bootloader
-
@MarkV I'm not sure I understand your question - bootloaders are programmed via the ISP interface (e.g. USBasp or ArduinoISP as programmer), not via serial/usb interface.
@tekka
Thanks for the replay.
I ment i trying to load the boatloader into a arduino pro mini (clone) through a Arduino (as ISP) Mega 2560.
When i try to upload the boatloader i'm getting this error:avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check. Fout bij het branden van de bootloader.What's wrong and what should i change?

@MarkV I had this message two days ago as well. I was programming with usbasp. I have solved it by powering my pro mini with a separate power supply. So please check the cables.

@dynamite
Oh thanks, will do that. .
But why does it giveel this message.. i wouldn't link this message to a failty powernapp supply..@MarkV Dont't know, it helped in my case. Whether it was actually the power supply is the question. But if it helps in your case as well, than most probably yes. I think it has something to do with the communication and it reads a faulty or no signature.

@dynamite
tryed it and got a other error report:avrdude: Expected signature for ATmega328P is 1E 95 0F Double check chip, or use -F to override this check. Verkeerde microcontroller gevonden. Hebt u het correcte board geselecteerd in het menu Hulpmiddelen > Board?What now?

@MarkV This is exactly the message I have received as well... Maybe check the other connection. Replace some cables? I the end I have been able to eliminate this message without changing anything in the software. In my case it was hardware related. (I was programming a pro mini and had it with two seperate mini's)

Hi,
I'm trying to burn 16Mhz version but I get the following error at the end:
avrdude: verification error, first mismatch at byte 0x0000 0x3f != 0xffProgrammer: Usbasp

@Mayank-Raichura I had the same problem with usbasp. The fix was to remove the -D flag (disable auto erase) when running avrdude.
@Redferne Thanks. I'll check it out.
