[Resolved] Problem to upload in UNO CH340

Hello, I'm using Win 7 64 (and another pc Win 8 64). Driver for CH340 is ok, and on the IDE i can see the correct COM and UNO. The UNO led green is on and the red led blink I try to upload a sketch (blink with modification of the delay) but the upload dont finich correctly.

Thank you. Problème de téléversement vers la carte. Voir http://www.arduino.cc/en/Guide/Troubleshooting#upload pour suggestions.

What is the problem ? Thank you

Did you use this driver ? http://www.wch.cn/download/CH341SER_EXE.html

I have no problem with Windows 7 64-bit and CH340G Uno clone.

Peter_n: Did you use this driver ? http://www.wch.cn/download/CH341SER_EXE.html

I have no problem with Windows 7 64-bit and CH340G Uno clone.

Yes I use this drivers. On the IDE, my UNO and the correct port it's reconized :


Arduino : 1.6.5 (Windows 8.1), Carte : "Arduino Uno" Using Port : COM4 Using Programmer : arduino Overriding Baud Rate : 115200


I have installed those drivers once more. Using Windows 7 64-bit and Arduino 1.6.5-r2. No problems uploading.

Is something wrong with the usb cable ? Could you try it on another computer with other cables and other Arduino board. If that works, exchange things until you find the problem. Sometimes the bootloader is corrupted. Do you have a programmer to burn the bootloader ?

I have tryed on a Windows 7 64 and W 8 64 with 3 differents cables. With my second UNO I have the same problem.

I try with IDE 1.0.5 r2 I have this problem : I don't have another programmer, only 2 x UNO

avrdude: stk500_getsync(): not in sync: resp=0x00

The newest Arduino IDE should work. Starting with version 1.5.x, the serial communication to upload a sketch has improved a lot.

A second Uno board with the same problem ? Then it is probably not a corrupted bootloader. Perhaps something ugly with drivers or old files of Java or old Arduino files. Did you install Java ? Please remove it. I use JavaRa to clean my computer from Java : https://singularlabs.com/software/javara/ Can you try to remove Arduino files of older versions, but not your projects files of course.

I try this but i have same problem. I have supressed Java, and i have this same result :

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xcf .... .... The rx led blink a few times but the upload is not complete done or not strart , i dont know....

Try choosing the board Arduino Duemilanove or Diecimila from the Tools, Boards menu and see if that lets it upload.

dmjlambert: Try choosing the board Arduino Duemilanove or Diecimila from the Tools, Boards menu and see if that lets it upload.

YES . with this modification of board the upload is done. Thank you.

Congratulations, you are the proud owner of a Duemilanove, not an Uno. You had better figure out how to pronounce it like I did, so you can tell your friends about it!
Or you can “upgrade” it to an Uno by burning the Uno bootloader on it.
