Upload broken for the Uno R4 WiFi on Windows 11 (Still Broken)

[mjs513]

While uploading to the WiFi board I keep having issues with it returning errors about not finding com port and can not upload even though the Wifi Board is shown in the boards menu along with the com port:

It appears to be hit or miss on whether it works - mostly misses. Sometimes it will work if I replug the board in several times most not. Happens even with blink. Not sure it is related to the PR #10, #10. At time of this writing none of these things work and stuck.

Note: Must have loaded a few dozen times before this issue cropped up

System:

Edition	Windows 11 Home
Version	22H2
Installed on	‎7/‎8/‎2023
OS build	22621.1992
Experience	Windows Feature Experience Pack 1000.22644.1000.0

Arduino Version: 2.1.1 Released

Version: 2.1.1
Date: 2023-06-30T16:04:40.277Z
CLI Version: 0.32.3

happens with Minima as well but can usually recover the minima by hitting reset twice and then uploading.

EDIT: Also just went through this.

Update: This fix seems to get it working but took a few tries to get the timing right: https://forum.arduino.cc/t/problem-uploading-to-board/1142928/34 - see my response in post #35

EDIT: Have to do this every few uploads. Annoying to say the least. Might be dependent on the current draw from the pins -have several I2c devices attached.

[mjs513]

When the issues are occurring is when I have several devices hanging off the I2C buses or have alot of data going to the serial monitor. Unplugging everything and doing the fix that @KurtE mentioned on the forum uploads are working no issue.

EDIT: also found that if I leave the Ser Monitor open in the Arduino IDE it works a well - tried twice now and seems to work

Hi, is there a slight chance that someone else is experiencing a similar behaviour on Mac OS Ventura 13.5?

Port, as well as Board are selected automatically, however the upload always fails:

No device found on cu.usbmodem ...
Failed uploading: uploading error: exit status 1

Already checked if another Application blocks the port, sadly this was not the case - re-install IDE 2.11 / Board did also not help.

@Plinfa - if you look on the Arduino Uno R4 forum you will see there are lots of folks having the same type of issues on all platorms. Seems to worse if you update the firmware

[Plinfa]

@mjs513 thanks for the info. Found a workaround on one of those sites. Pressing the reset button halfway through compiling solves the issue (at least for me). Since then, I had no connection problems at all - I assume as soon as the sketch is being closed and re-opened, it will fail again.

@mjs513 @Plinfa what WiFi firmware version are you using on your boards? 0.1.0 or 0.2.0?

[mjs513]

@pennam - been testing on the minima, Wifi 0.1.0, and 0.2.0 (have 2 boards). Was kind of giving up on Wifi because of the uploading issues.

[pennam]

@mjs513 is upload failing with both 0.1.0 and 0.2.0? Are your boards from the early access program?

[KurtE]

Sorry I am not @mjs513 and only have one wifi board, currently at 0.2.0. I had a few times with the 0.1 version that failed to upload. Most of the time it was easy to rectify. double click reset, make sure no other windows open with Serial port, etc.

After update to .2, the upload failures happen a lot more, and resolving them, a lot trickier. I suspect that there are timing windows in the code, where it works and where it does not, and you just have to hit it right.

@KurtE Thanks for your feedback!

@mjs513 @Plinfa @KurtE We have just made a pre-release of a new firmware 0.2.1 that should solve the issue. Do you mind give it a spin? You can download the updater package from here:

• windows
• macos
• linux

[mjs513]

@pennam - just tried to download the windows version but it the zip file name is -update-linux.zip? Don't think thats correct

@mjs513 i've fixed the link!

@pennam

1. update.bat ran smoothly (note this is on a wifi board running 0.1.0
2. Just updated from 0.2.0 to 0.2.1 no issues. But why Adafruit Qt Py ESP32-C3 after upload :) until I unplugged it and replugged it back in

Uploaded a few the sketches I used that had issues and looks like the fix is working. Only time will tell but feels right. As I said so far so good!!!! Nice work.

PS. Looks like it fixed the issue I was having with it loosing the output to serial port when opening and closing it.

Think you are going to make a lot of people happy
