Arduino not working / not uploading [duplicate]

Question

Could anybody please help me with my problem? My Arduino doesn't work correctly. I was between a project, and suddenly it started acting weird. First, it started taking about 4 minutes to compile and a minute to upload, I do not know why!

Second, now it doesn't accept any code at all. I will paste the error message below.

Also, could anything be damaged as I inserted the USB cable of the Arduino to my power bank, rated 5V 2A, for about 30 seconds as power source and then again inserted it to the computer itself.

Please help me. I have already tried searching on various forums, reinstalling the software and driver on my PC, pressing the reset button... No help so far.

avrdude done.  Thank you.

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

Answer 1

Connecting to the 5v/2A power supply would cause no trouble at all. Taking 4 minutes to compile is strange but unlikely to be related to the Arduino board. "programmer is not responding" errors are communication errors.

• Did the program compile without errors?
• Are any LEDs lit or blinking on your board?
• Is the correct board selected in the Tools | Boards menu?
• Is the correct port selected in the Tools | Ports menu?
• Is the correct programmer selected in the Tools | Programmer menu?
• Try another USB cable.
• Try pressing/releasing the board's reset button right after you click the upload button.

Answer 2

I am getting the same exact errors. Tried different boards, cables, upgrade to 1.6.7, etc. Maybe will go back to pre1.6 and try. Will also try via tinyisp when I get a chance. FYI - having no issues with studio 6/tinyusb/avrdude combination, just on arduino. Wonder if it is a USB driver or arduino version of avrdude problem?
