I got to Vienna a couple hours ago, unpacked the sculpture, plugged in to modify the program, and of course it isn't working. I'm using the same laptop, the same arduino, nothing was added, nothing was taken away. My code verifies ok, and the arduino runs the sketch I last loaded into it just fine.
The message I am getting is
avrdude: verification error, first mismatch at byte 0x0000
0x39 != 0x00
avrdude: verification error; content mismatch
I'm not finding anything of much use checking AVR Dude forums.
Any help? The opening is in a couple hours!!! Many thanks in advance
Nothing else is plugged in. I'm using version 10 of the software. I'm using an older board with the ATMEGA8 and USB. Same FTDI drivers as before. Happens whether powered by external power or USB. This is one of those things where it worked fine last night (and had been for weeks), but not now. I do the upload process, it finds the board, and the USB LEDs blink, as usual, so I know it is finding the board and communicating with it. And my code compiles fine.
As far as another arduino goes, I brought a bare bones board along, but I had never tested it until now (in fact I just soldered it up here in the gallery) and I get different errors when I try to upload a program to it - I get a sync error with that board:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
I will try that. I got home last night around 3AM and came into the office this morning - my body doesn't really know what time it is yet. As soon as I unpack I will set up the sculpture and try it.
I thought of uploading a tiny sketch to it, but then realized that it was currently running a sketch that if all else failed would at least animate the piece somewhat - and if I changed that and couldn't go back, and couldn't get the new board to work, that I would be 100% screwed.
<<<Did you try uploading a simple sketch to the board?>>>
Yea, the entire sketch for the piece is pretty simple as it is - around 2K is all in its current form.
I soldered together the other board in the gallery, hooked it up, and it worked all though the show so everything worked out in the end. I'll start hacking on the other board tonight or tomorrow.
The same exact issue just happened to me. I tried to upload the the first LED flash code from the tutorials, and I got a similar error (with a different address):
avrdude: verification error, first mismatch at byte 0x0042
0x9d != 0xd0
avrdude: verification error; content mismatch
I'm using a Freeduino with the ATMEGA168 chip and there are no wires plugged into any pins. It is being powered by the USB port.
I set upload.verbose = true, and I received more data that I could not understand; I could not fit all of it due to the character limit set on this post:
I ordered a Arduino Diecimila board as a replacement; it worked with the Arduino IDE, which shows that it's a problem with my Freeduino. I realized that I could also replace the ATMEGA168 chip for $5, and see if I can still use my Freeduino.
I should get it in the mail somewhere around next week, so I let you all know if it works; I'm sure it will, since the chip is basically the heart of the board, and I doubt that it's a problem with the Freeduino board itself that would just instantly pop-up.
The last thing I remember doing with my board is uploading code to operate an LED with a potentiometer, and I made a 9V battery adapter that works with the Arduino also. I also kept unplugging and replugging the battery in, but I don't think that would cause a "Verification Error" over time.
Thank goodness that the ATMEGA168 chips are cheap.
Anthony, what Freeduino board do you have? Is it the KIT based board or the assembled prerelease board?
Hello. It's an assembled Freeduino pre-release board; when I received it, it was the board alone with its own ATMEGA168, and it came with nothing else.
I have the same trouble as the first person posting in this thread..
The arduino i use is caled "Arduino Diecimila compatible USB board complete KIT with pre-soldered FT232BL"
i got it from Ebay. The bootloader is probably 9.. and i was using editor version 10
It was working just fine until i uploaded this script http://www.arduino.cc/en/Tutorial/StepperUnipolar
The stepper motor was connected while i was uploading.. but i think i connected it wrong.. because it did not start rotating..
After this i tryd a different connection. but still no luck..
Then i disconnected everything and tryd uploading the BLINK script.
I set "upload.verbose = true" and noticed the verification message was giving back only zeros
Then i was thinking the Atmega168 is probably burned out or something, but after some more fiddling around with the arduino.. i noticed the stepper motor script was still on the arduino. and working.. I just cant upload a new script to the arduino..
So what could be the problem??
Could the upload part of my arduino be broken (the USB to serial converter)?
Or could it be something else..
The ATMEGA168 chip I ordered arrived in the mail today. I replaced it with the one in the Freeduino, and it works just fine.
This proves that it's a problem with the microcontroller chip itself and not the board. However, I don't know how to actually fix the problem.
If you're willing to spend $5, you can order a new one to replace the one in your board. As of the verification error, I don't know what to do about that, so I'll just hold onto it until there's a way for me to deal with it.
I also ordered the "Arduino Diecimila compatible USB board complete KIT with pre-soldered FT232BL" from NKC on eBay..
I hope I don't have this problem while I'm messing with it :o
do you think i should order some spare ATMEGA168 chips just in case? :-/ seeing as I am a total noob at Arduino, microcontrollers, and programming

Were you able to solve the problem by replacing the atmega168? If not, then contact me to my email freeduino at nkcelectronics dot com.

not that i don't understand what its about
The Arduino/Freeduino are prototyping boards, and it means that a lot of bad things can happen to them while developing new electronics applications. It is always a good practice to have a couple of spare atmega168's, maybe you want to keep one with a sketch programmed, or you want to deploy it using some barebone Arduino boards, etc. I received only a couple of problem reports with the kits. I burned an USB chip on a freeduino board just by placing the board on top of some wires by mistake, while it was connected... so a lot of things can happen to these boards while you are prototyping projects with them.

I'll bare that in mind. i'll have to make an anti-static surface to work on and keep my wires away from the underside
i'll prolly get more chips soon too just to make sure i have some spare for projects and emergencys
Same has happened to me. The sketch on the board continues to function correctly but I cannot upload new sketches.
Thankfully I picked up a spare chip when I ordered my board. - phew!
Guess I gotta pull in a Bare-Bones jobby for the old chip and retire it into permanent application. (It's running an automatic PIR sensor driven night lite)
I've had the same problem with two Arduino Mini. Without any reason (same software, same USB interface, same PC, almost same moment,...), suddenly, I can not upload the program. (I got the same "avrdude: verification error, first mismatch at byte 0x00xx" and that staff)
I've programmed the Arduino before hundred of times, so I think it's not my fault. I've tried to use avrdude to solve the problem, but no way; I am able to read the flash content, but I am not able to read the state of the lock bits or upload any skecth to the flash (well, I´m not an expert with avrdude, and perhaps there is something I'm missing, but I don´t think so).
I only find two possible explanations for this:
First one; Perhaps I've programed the flash too many times (Atmel guarantees 10000 cycles). Well, I´ve tried to figure out how may times I´ve programmed the arduino, probably 1000-3000 times, but I´m sure I´ve not reached even 5000 cycles. Could be a defective part, but it happened to me with two parts.
Second; for any strange reason, the flash has been locked, and I'm not able to reprogram it. As I said, I can not read the lock bits with avrdude (any clue to do it?). I can not even read the flash or the eeprom in terminal mode (I always read 0's), but I can dump their contents to a file in command line mode (I don't know this is the normal behaviour or not)
Any idea or help? Due to this problem, I had to unmount a really complex piece of hardware with the Arduino Mini deeply embedded inside, and change it by a new Arduino (and, of course, the day before the demo... a nightmare, you know). I´m really worried about this, because now I don´t feel like using a platform that it is not reliable, unless I can understand what was the reason for this failure.
