I had few problems with uploading sketch to Arduino on win10.
There are two option to try for fix...
1.) Run IDE as Administrator - it worked for me first time but then it again stopped working.
2.) I don't know if it's some win10 update, but from yesterday night I had problem with uploading in one moment. I then found, that avrdude is not able to start properly.
Problem is in library libusb0.dll. To solve this problem, simply download libusb from here: Download libusb-win32 from SourceForge.net extract libusb-win32-bin-188.8.131.52/bin/x86/libusb_x86.dll and rename it to libusb0.dll. Then copy libusb0.dll to C:\Program Files (x86)\Arduino\hardware\tools\avr\bin
The developers are already aware of this issue(Windows 10 64Bit, Arduino 1.6.10 upload issue. · Issue #5173 · arduino/Arduino · GitHub) and it will be fixed in the next release.
Good work finding the dll solution! That one had the Arduino developer confused for a while before he figured it out.
There is a bug in Arduino IDE 1.6.10(and possibly Arduino AVR Boards 1.6.12 used with any IDE version) that can cause that issue when you start the IDE by opening a sketch(.ino) file(by double clicking on it, etc.). You can also fix it by doing this:
- Close all Arduino IDE windows
- Start the Arduino IDE, not by opening a sketch file.
- Open the sketch file via File > Open, File > Sketchbook, or File > Examples
The last opened sketch will automatically load when you open the Arduino IDE, that one should also work fine.
Thanks for quick reply!
The solution with opening last sketch or examples sketch didn't work for me...
