1  Using Arduino / Installation & Troubleshooting / Re: Uno SMD r3 arrived in DFU, installed FW & bootloader, now 'out of sync' on: May 06, 2013, 05:22:19 pm
Thanks for your time, you have been really helpful this whole thread, I do appreciate it!
I have contacted RS-online and they are shipping a new board out to me and don't need the old one back.
I think I'll try writing sketches straight to the chip using either ArduinoISP or an ICSP cable I am yet to build (I ordered a PCIe parallel port for $4 and found the tutorial for the cable) to use if I ever decide to make a project a permanent product. On that note could someone direct me to a tutorial on the process of getting a sketch running with no boot loader, specifically what if any changes do I need to make to my code?

Thanks again everyone for all the help

I have tried to burn the uno bootloader a number of times. All apparently successful (no error LED, heartbeat LED ok, everything fine) but it didnt make any difference.

However I was just reading another similar thread here and saw James C4S talk more of knock off boards being Duemilanove and in combination with his suggestion above (of trying different selection under board type), I decided to burn the Duemilanove bootloader.
That definitely made a difference. The pin 13 led now flashes slowly, longer off than on, but still within 1-2 second cycle. I guess that shows my bootloader burning is working, and from above, my loopback is working, what else could be going on?
Even with the Duemilanove bootloader I still get the same error, even switching between Duemilanove and uno under board selection when uploading sketches.

The voltage across the led is around 1.8V, does that mean flickering very fast?
Changing between Uno and Duemilanove even a few times made no apparent difference

Yeah, that shouldn't have done anything since you can't program the bootloader without a programmer.
Thanks for clarifying that.

In answer to the question if the pin 13 led flashes on reset, yes it does, it flickers on/off a few times, the goes dark for a sec, then lights solid from then on

The firmware i am using on the 16u2 is either 'Arduino-usbserial-atmega16u2-Uno-Rev3.hex' or 'Arduino-usbserial-uno.hex' I have used them both without success, currently the r3 version is installed.

The loopback test works fine, I get back in the window everything I type in the text field

The only other thing I can add is that when I attempt to upload a sketch, the pin13 led flashes a few times and goes straight back to solid, and the Rx led flashes a few times, then nothing. I get no activity on the Tx led

I think I have already done this, by a different method.
Isn't it what I did when I loaded the 'ArduinoISP' sketch onto my new board, wired it to my old board, then set use 'Arduino as ISP' as the programmer in the ArduinoIDE and clicked install bootloader? I thought this was bypassing the 16u2 to install it straight to the 328p, because this succeeded.

edit: For the sake of completeness I attempted to load the bootloader over usb from the IDE but I received this error
Quote
avrdude: usbdev_open(): did not find any USB device "usb"
remembering I have another Uno working perfectly, so this is not a driver issue
this makes me think the source of my problems is either the 16u2 (it did arrive in DFU after all) or between that and the 328p

Does this point to any other possible solutions or should I start writing for refund/replace?

Thanks for clearing up the roles of each chip and what I was actually doing when running FLIP.
I followed the tutorial, but it was basically what I had done in the first instance, other than shorting the reset to ground, I was then able to connect and update the firmware again, I tried a few that were recommended in different places, all loaded successfully using FLIP, I hit 'start application', and then windows detects and installs it as a Arduino Uno, but I still get the same ' avrdude' error when trying to load a sketch

Hi,
I recently posted here and received very good help here about a Arduino Uno SMD r3 that arrived already in DFU mode, I used FLIP to install the bootloader successfully, but still have been unable to successfully load even a single sketch to the device.
The error i always get is
Quote
avrdude: stk500_getsync(): not in sync: resp=0x00
Thinking i may have done something wrong, I went back to FLIP, only to find that when I went to open a USB connection I got another error
Quote
window title 'com.atmel.flip.IspException'
content 'could not open USB device'
Which i thought was odd, as I had just used FLIP to load the bootloader only minutes earlier and had succeeded.
So then I figured the board was probably dead, and I'd have to buy another board anyway, so i did, an Uno r3 (but not SMD this time).
In doing some research while the new board was in transit, I found you could use one board to load a bootloader to another, so I did this using the ArduinoIDE, successfully.
But alas this too did not resolve my issue, I still get the same 'avrdude' errror
I am using the same cable for either board, and I have nothing other than the USB cable plugged into either board when programming

I have two questions,
Firstly: Is there anything anyone can think of I have not done that might yield a better result? I'm sure I could probably burn sketches straight to the chip without bootloader, using either my new board or an ICSP cable (which i don't have, nor a parallel port), but this is a pain, and really defeats the purpose of an easy to use board.
Second: Does this sound like a legitimate case for seeking a refund from the retailer? (it was RS-online)

Thanks for your time
Chris

Thanks,
I have downloaded this, installed it and the JRE, opened it, selected the mega16u2 and loaded the appropriate hex file, but when selecting a communication medium as usb (USB is the only one not greyed out) i get this error imaged below then one that says 'couldn't load dynamic library'. this is all while the options to erase/blank/program/verifiy etc are all greyed out


edit: some quick google work and again forcing it to install an Amtel usb driver got through that part. BUT even after reprogramming it leaves me with an 'Amtel USB Devices>ATmega16U2' in device manager instead of a 'Ports' device from which to install the driver.

edit2: hang on, in Flip i did everything but didn't know i had to hit 'start application' after hitting 'run'. everything now works as it should, and the driver auto installed correctly to use it as a com3 port. still don't know how i put it into DFU but whatever, it now works, thanks again

Hi,
I'm trying to install a Uno SMD r3 on a x64 Windows7 machine. after the auto install  failed, i followed directions to go to device manager and install it that way but it was listing it in 'other devices' not as a 'port' device. Even after directing the installer to look in the arduino driver folder it still wasnt working. I then directly told it the device was a 'port' by selecting 'update driver>Browse>let me pick>ports>have disk>' then selecting the arduino driver package and then scrolling down to the Uno. but it still failed with an error 10 'device cannot start' (see image)
i then uninstalled the device which then made it show up as 'ATmega16u2 DFU' (see second image). now from what i know of jailbreaking iphones, DFU isn't where i want to be.

I've run out of ideas, already tried installing on an older XP machine but to no avail.
any assistance would be appreciated,
Thanks
Chris
