Those UNOs and even the clones are hard to break, not impossible, but not easy doing what you have been doing. It is MUCH more likely that WIN 10 is being a jerk.

Continue with your restore and the other steps. Chances are that in a few days, you will have two UNOs and they both will be working.

Hang in there!

After ~ 30 mins I manually restarted Win 10 and got message that the restore did not complete.

I took your steps. (Except no BlueTooth and I don't know how to easily stop Defender - an unlikely culprit anyway IMO).

Here's the obscure and very long 'error messages' text:

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

Terry, East Grinstead, UK

 

Look at post #20

 

@be80be

But how can I square that diagnosis with the behaviour I've described? The board DID work until a couple of days ago! The cable is OK (I found a replacement to test it.) COM3 is consistently reported. And the identical problem occurs on two PCs.

I agree. This would tend to implicate the board, not the host computer or OS.

Bob

 

Bob this is what happens when you pick wrong comport
there is no com3 on windows XP that you can use as usb comport or I have never seen one and I think in over 20 year messing with this stuff there be one LOL
There is a com3 just it's not usable for a added comport its saved for the serial ports if your computer has one.
Back in the day com 1 and com 3 was one port and com 2 and com 4 was one
the bios reserved them
if you open up arduino without anything hooked up it gives you a pick of
com1 or com 3 on my computer.
plug in a working usb to serial I get com 4 and up depending on who made it.

An error occurred while uploading the sketch

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

 

After ~ 30 mins I manually restarted Win 10 and got message that the restore did not complete.

I took your steps. (Except no BlueTooth and I don't know how to easily stop Defender - an unlikely culprit anyway IMO).

Here's the obscure and very long 'error messages' text:

Arduino: 1.8.9 (Windows 10), Board: "Arduino/Genuino Uno"

/--/
Terry, East Grinstead, UK

OK, good.

First, you can attach a text file as I have done here. That way, folks can read the formatted text without it looking crappy in the post.

You're getting multiple folks helping you with various suggestions, but I think that is ok. I try to be as systematic as possible but we are not there and your perception of events as a new user might be very different than mine.

I still am not convinced that the board is bricked. It may be, but there are other explanations.

Note that you have not disabled antivirus.
You are running IDE in supervisor mode.
You do not have any bluetooth dongle or devices (no ble keyboard etc..)
You compiled blink and it compiled fine but could not communicate with the board.

You have two threads here, the first being when you decided to get the system. Is it correct that you used this board on the WIN 10 machine successfully and then you used the board on the XP successfully and then the problem occurred? Can you post the straight facts about that as well as you can remember? Were you doing ANYTHING that might have bricked the board? Did you have components on the breadboard attached, etc..

You have a new board coming in and you could wait for that to arrive. Alternatively, you can continue to debug the connection on the board that you have.

The next step for the latter, in my opinion, is to look at the device manager and see what Win 10 says. I mentioned this in post #14 as did @be80be in #20 and #22. That is the next step, if you are up to it...can you take screenshots or figure out how to do that and post them?

Beyond that, there are a number of tests that you can perform to see if it is bricked. Look at this long thread https://arduino.stackexchange.com/q...-arduino-uno-problems-with-uploading-to-board carefully. But, again, your next step is to look at the device manager...keep the XP out of it for the moment.

That's what I think.

 

Open up the device manger and then open ports and post a screen shot
It should look like this only it should show what chip your using for usb to serial
View attachment 178349

 

Ok lets look here I plugged in a real uno this is what I got

 

Try this click on the comport go to advanced settings and change it on the bottom box to say 5 sounds good and try it out.
Im about sure windows XP saves com port3 and shouldn't give it that number but
I'm sure windows is buggy on com ports had it happen some weeks back on a new TCS the computer was giving wrong comport to the second TCS

If He's on windows 10 his problem still the driver windows 10 has very good usb to serial but just one problem it will show as working with windows driver and no errors but
the port will not respond

You have to remove the driver and reinstall in unsigned mode.

O and one more thing if you have usb 3.0 or above that maybe the problem too if your no in a 2.0 hub like my laptop it has one 3.0 and 2.0 ports

 

OK, good.

First, you can attach a text file as I have done here. That way, folks can read the formatted text without it looking crappy in the post.

OK, understood thanks.

Yes, correct.

Can you post the straight facts about that as well as you can remember? Were you doing ANYTHING that might have bricked the board? Did you have components on the breadboard attached, etc..

I can't remember exactly but at one stage I did drive a solenoid (with protective diode in parallel) via a power MOSFET. That was working OK. Then a bit later after editing that code the described symptoms arose. Since then the only components I've had on the breadboard are an LED and its 220R resistor. And nothing at all for the 11 hours today.

The chip is plainly working, at least to some extent, as it's still flashing the last sketch uploaded two days ago. But I'm seriously concerned that I must have screwed something up!

I've confirmed several times that the port is set correctly. Checking Device Mgr was an obvious very early step. I've been using PCs since 1982! I posted a screenshot about an hour ago in post #26 FWIW.

Beyond that, there are a number of tests that you can perform to see if it is bricked. Look at this long thread https://arduino.stackexchange.com/q...-arduino-uno-problems-with-uploading-to-board carefully.

Thanks, I'll study that.

And thanks for patiently staying on the case!

 

Have a look at this
https://superuser.com/questions/389...s-com-port-x-reserved-want-to-reclaim-the-por
It shows you how to see if something else is using com ports

 

Bob this is what happens when you pick wrong comport
there is no com3 on windows XP that you can use as usb comport or I have never seen one and I think in over 20 year messing with this stuff there be one LOL

@be80be re post #28

Strange, thought I'd replied to your post #28 a while ago, but it's nowhere to be seen. Here's the screenshot I included. But it made no difference, so in a minute I'll change back to COM 3.

 

windows 10 is same check the hiding usb ports and comports
from the looks of your screen shot it found a arduino
has to be one or the other two things want that port or it's loaded the windows stock driver.

 

Pessimism factor rises

Here's part of the StackOverflow post that Raymond recommended;
Try uploading a sketch
Choose one of the simple example sketches (eg. Blink) and try to upload it. This is what you should see:

• The "L" LED should flash 3 times. This is because the main chip is being reset by a command from the uploading process.
  
  
• The "Rx" LED should flash quickly. This is the instructions from the uploading process trying to activate the bootloader.
  
  
• The "Tx" LED should flash quickly. This is the processor acknowledging the uploaded data.

I get none of those three. Looks like the USB Interface is broken!

"...or it's loaded the windows stock driver."
That may be worth exploring because I've been puzzling why the driver details do indeed seem to show a 'generic' USB driver, not one especially for Arduino.

What does yours show?

 

Could you post 2 good pictures one of the front and one of the back of your uno
My windows 10 shows it using the same you showed

I think you should stay the course. I was worried that if I posted that thread you would jump to the more familiar hardware angle

 

Even if you did kill the usb to serial chip you can still program the 328 with a FTDI usb to serial adapter

Which I don’t have and suspect I would be on a learning curve before I could confidently use it.

Will do, FWIW, but probably tomorrow morning. I’ve been on this since 07:00 and it’s 22:30 now!
