Problem Downloading code to Wifi Rev2

[ghost]

My code compiles fine but when I get to the downloading part of a new install I get the following error. At the bottom of the error list it says the board is not connected but when I get the board info the window shows the correct info.

Arduino: 1.8.9 (Windows Store 1.8.21.0) (Windows 10), Board: "Arduino Uno WiFi Rev2, None (ATMEGA4809)"

Bernardo,

Did you change your code so that you were forcing the compiler to use more flash instead of RAM? IE

Serial.print(F("Write something on the Serial Monitor that is stored in FLASH"));

Or

const char StyleHTML[] =" some long string like a web page”;

My issue started after I started using these.

Unfortunately, that is not my case.

[btabuenca]

Just tried with a 2nd Arduino UNO wifi rev-2 that was working this morning. Now I get the same message and did not modified any line of code.

This is how things happened:

1. I tested it in Genuino linux this morning. Worked!
2. I tested it in Genuino Mac this afternoon. Worked!
3. I tested it in Genuino linux this afternoon. Did not work :(
4. I tested it in Genuino Mac this afternoon. Did not work :(

Now I have 2 Arduinos UNO wifi rev-2 not working. I cannot upload any program

Please let me know if I could help

Since yesterday I have the same problem with my Arduino Uno Wifi Rev 2. It would be great if someone finds a solution for this bug. I also wrote an email to the Arduino support and I am waiting for an answer.

Is it maybe possible to exchange the defect Arduino, because it is in the warranty time?

My actual project is a multi medial steering platform for the Tinkerkit Braccio and the Arduino is the leading component for me.

Sorry my picture did not go thru.

I am getting the same issue. Arduino Uno Wifi Rev 2, purchased today. Was working perfectly. Ran the WifiNina check firmware version sketch, it worked. Loaded the WifiNina update firmware sketch, tried to update and got this:

avrdude done. Thank you.

[facchinm]

Didn't want to close the issue directly, but thanks to the replacements you sent us we have a solution :slightly_smiling_face:

First of all, the problem is probably due to a bug in avrdude, which incorrectly writes the CRC bits (fuse SYSCFG0 - 0x05). Once CRC is wrong, the only way to unlock the chip is through an unlock/chip erase procedure which differs from the normal chip erase. This procedure was triggered only in case the return value of avr_signature was -68. Due to other changes, mEDBG reports -67 as errors, so it doesn't trigger the right erase procedure.

I'm currently producing new avrdude builds that should fix the error. In case you want to test before the official release, the right commandline is

bin/avrdude -C etc/avrdude.conf -v -patmega4809 -cxplainedmini_updi -Pusb -b115200 -e -Ufuse2:w:0x01:m -Ufuse5:w:0xC9:m -Ufuse8:w:0x02:m

Core 1.8.1 had just been released, boards exibiting the issue will just self-fix on the first upload using the new core :smile: @jan1za @TimEllis2019 @per1234 @btabuenca @jguen @OmriEg

[ghost]

I just downloaded the new core and was able to reprogram my “failing Wifi Rev 2” board.

One comment, when I went to the board manager it did not tell me a new version of the code was available like I remember in the past when changes were made. I had to look at the download list to see 1.8.1.

Thanks for your efforts on this.

Thank you for all the work. Unfortunately I exchanged the WiFi rev 2 for a yun as I needed a working demo for today else I would have tried the fix.

Core 1.8.1 had just been released, boards exibiting the issue will just self-fix on the first upload using the new core 😄 @jan1za https://github.com/jan1za @TimEllis2019 < https://github.com/TimEllis2019> @per1234 https://github.com/per1234 @btabuenca https://github.com/btabuenca @jguen https://github.com/jguen @OmriEg https://github.com/OmriEg

Thanks for your work guys! Now it works.

Just for your information in case it helps ... now I get the following warning:

avrdude: WARNING: invalid value for unused bits in fuse "fuse5", should be set to 1 according to datasheet
This behaviour is deprecated and will result in an error in future version
You probably want to use 0xcd instead of 0xc9 (double check with your datasheet first).

I get this too. Using an Uno wifi rev2 in both arduino IDE and Visual Studio 2017 with vMicro plugin.

Things seem to work anyway, do I need to fix anything? if so, how can I 'use 0xcd instead of 0xc9'?

@EbStewart no. See https://github.com/arduino/Arduino/issues/9443

My version of the compiler works fine. I get the same warnings but my code works.

Mine seems to as well, but I want it to continue to do so. If this blows up at the last minute I'm screwed, so I want to be sure.

Should this still be happening as of late July?

Mid August of 2020 and I am having similar problem. I tried it on 2 different computers using Windows 7 with same result. I ordered a new "Uno wifi Rev2" board, but want this one to work too.

I didn't get quite as far as those above. Com Port seems to show up correctly and appear / disappear when I plug / unplug usb cable. I am trying to upload simple blink program. Error report:

Any and all recommendation or advice is appreciated. Thank you.

Check your board manager. Your library for arduino megaARV boards should be 1.8.6. It's been a while but I think that fixed my issue with this. -tim

[iowagrade]

Hi Tim, Thank you for your response. I have been using the updated 1.8.6 version, but happened to be cycling through uninstall and trying different versions when I copied that debug report. Now it says: avrdude: Version 6.3-20190619

Some other possibly relevant stuff: -The mEDBG Virtual COM Port driver I am using is version 6.0.0.1 from 6/14/2013. -The firmware updater for wifiNina says it can't connect to the board -The "get Board Info" command responds with information that seems to recognize board type and has SN -I tried installing Atmel Studio, but didn't seem to get any updated driver files.

I ordered a new Uno wifi Rev2 board which should arrive Monday. Hopefully it will work, but any other suggestions are welcome.

[iowagrade]

I just tried it with the arduino online tools. They recognized that it was an arduino Uno wifi Rev2, but everything else was the same as far as error received :(

[EbStewart]

Why are you using the setting emulating ATMEGA328? I did have mine working well when set to Atmega 4809. (But now something else has blown up. I'll come back to the discussion later, time permitting.) Anyway, see if that has anything to do with your woes.

[iowagrade]

Thank you for the reply. I tried that too. In the Tools menu > Registers Emulation, the 2 choices I get are: ATMEGA328 None (ATMEGA4809)

Then the first line in the output shows: Arduino: 1.8.13 (Windows 7), Board: "Arduino Uno WiFi Rev2, None (ATMEGA4809)"

The only other thing that shows up different in the error output is at the very end, it says: the selected serial port does not exist or your board is not connected

And I still receive information with either Registers Emulation mode when I exercise Tools > Get Board Info

[barrypress]

That’s what I have loaded, and my UNO WiFi rev 2 continues to have the error; UNO does not.

Thanks

Barry

2 months since the last post made here, I still have this issue and I'm unable to fix it. I thought it was a linux issue (I used arch linux for the record) and now I've tried it on windows and I have word for word the same issue. I've tried many versions of the megaARV boards including the latest (1.8.6). I have an equivalent of the UNO WiFi Rev 2 but it seems to be identical to my understanding. If someone could shed some more light on this issue that would be great, please and thank you.

Edit: I want to mention on my COM(3) the board is shown as simply an Arduino Uno (which it isn't) if that's a factor

[manilal2]

I have custom made PCB using ATMEGA4809 (according to schematic ( https://camo.githubusercontent.com/0318ea09473584a26d3f653e1501e8ba43a524259eb7dfe0a36920a9d6d7bd05/68747470733a2f2f692e696d6775722e636f6d2f784e6778627a582e706e67))

how do you execute chip erase using updi...?

[manilal2]

I was able to program third board using atmel ( microchip) studio , where I erased it before programming , after programming verification was successful , when I try to flash sketch ( led blink sketch ) it gave me (bootloader and arduino IDE verification error , subsequently I tried to reprogram atmega4809 ( 48 pin) bootloader and I was not able to put in program mode , is there some fuse setting which will allow me to put atmeag4809 in program mode , right now I am unable to program it ( it says unable to put atmega4809 in programming mode , once program I am unable to erase it )

also what bootloader I should be using my parameters are 20Mhz internal clock, baud rate 115200,optiboot UART on serial 1 ,BOD 2.6v ,48 pin standard, Reset pin Reset , can some one give me filename for bootloader and where it is in arduino ide...?
