Avrdude: verification error. Help!

Hi All,

I was trying to upload a bit of code and got this error:

avrdude: verification error, first mismatch at byte 0x0086
         0x04 != 0x44

I'm still very new to arduino and have no idea how to fix this. I've searched the forum and found nothing helpful other than it might need to be told to wipe the previous code before uploading the new code and isn't, which is causing the problem. Is this the case and if so, how can I solve it? I know the code I'm uploading is fine and working as I have uploaded it to another board and it works fine.

Thanks in advance!

Jack

Board?

Hi Coding Badly,

Thanks for moving my post, I'm still finding my way around on here!

Its an Arduino Uno board. I've got three of them and the code works fine on the other two but I need them for other projects so I really need to find out whats wrong with this one :disappointed_relieved:

Thanks again,

Jack

Hi Coded Badly,

Is this what you mean?

Binary sketch size: 5,020 bytes (of a 32,256 byte maximum)
avrdude: verification error, first mismatch at byte 0x0086
         0x04 != 0x44
avrdude: verification error; content mismatch

Or something else? Sorry, I'm not the best at this.

Thanks again,

Jack

Hi Coding Badly,

Sorry, got what you wanted.

avrdude done.  Thank you.

Sorry the Verbose output is in 3 parts, it was exceeding the 9500 character limit.

Thanks again,

Hi All,

Could someone tell me how to reset the arduino to factory settings? I think its worth a try and might solve the issue.

Thanks again,

Jack

dantedraven13:
Its an Arduino Uno board.

Where did you buy it?

How old is it?

dantedraven13:

The closest thing is to re-burn the bootloader. All you need is some wire and a second board.

I think its worth a try and might solve the issue.

I agree.

From Maplins Electronics about 4 or 5 months ago.

How would I got about doing that? I have a second board a can use.

Hi Coding Badly,

I found an online tutorial for reinstalling the bootloader here:

https://www.sparkfun.com/tutorials/247

However, after doing this I get this message now:

avrdude: stk500_recv(): programmer is not responding

Any ideas?

Yeah. Don't use that tutorial. It's missing at least one important step and the wiring method is just plain stupid.

Give this one a try...

Hi Coding Badly,

Can I do this without the resistor? I don't have 10uF ones and I'm pressed for time so sourcing one is an issue. Also, I've bought a completely new board and encountered the same error as first listed. Could something in my circuit cause this error? I've tried uploading the code to another board and its working fine so I'm worried the circuit might be the issue, although its exactly the same as the other one with the exception of running off a different power supply, however they are the same voltage and amperage (9v, 2A). I've updated my arduino software and that hasn't solved the issue either.

Thanks,

Jack

dantedraven13:

"Resistor"? Did you mean to write "capacitor"?

Are you asking about a 120 ohm resistor connected from RESET to +5V to disable auto-reset?

Or you could cut the auto-reset trace.

I don't have 10uF ones and I'm pressed for time so sourcing one is an issue.

Anything larger will work. Smaller may work. The capacitor size is not very important.

dantedraven13:

Do you have anything connected to pins 0 or 1?

No, the only pins used are 3-11, 5v and Gnd.

Hi Coding Badly,

Thanks for all your help! Finally got it working :smiley: Managed to reprogram the board using the tutorial you posted and it all works fine now.

Thanks again,

Jack
