LEDs do not blink. Upload ends with timeout.

I use Arduino IDE 1.0.5

Arduino is detected as a device (see the image). But in Arduino IDE or my own program which lists all available serial ports it is not listed. There is COM3, but it obviously is the native COM3 - because the programs does not communicate with Arduino.



4  Using Arduino / Installation & Troubleshooting / Arduino Uno serial port conflict on Windows on: January 23, 2014, 07:43:44 am
I have PC with 7 native serial ports with Windows 7 32 bit running on it. I installed Arduino IDE 1.0.5 with the USB/serial driver.
When I plug in Arduino Uno new COM port is added in device manager "Arduino(COM3)". But there is already native COM3!
No program, not even Arduino IDE, is able to communicate with Arduino. No new COM port is listed. That same Arduino and IDE works perfectly on a laptop without native serial ports.
I cannot communicate with Arduino on this PC at all ! Is there a way to solve it?

Problem solved - I selected Mega 2560 in IDE while I have Mega 1280. There is no problem uploading after selecting the correct board.
Sorry for bothering you, my mistake.

OK, I will try that. If it will be clear that avrdude is the source of troubles what info can I try extract so that we know more about the core cause ? Is there any log ?

No shield. The question is why does it work with the old version.

Even the blink example is not uploaded. RX LED twinkles a little bit and that's all.

I have windows XP, SP3.
I thought there is a driver problem, but  anything I did with the drivers didn't help.
I was desperate and I tried older version of Arduino IDE and uploading was working smoothly.
More info about the problem: when I click upload button in IDE rev 1.0, the progress bar gets filled for ~ 80% and than the program hangs. It's not possible to open the serial port any more. There is a deadlocked process "avrdude". If I kill it, IDE is responsing again and serial port is accessible.
10  Development / Other Hardware Development / Powering Mega 2560 with 5V on: March 08, 2012, 03:38:00 am
In my project I have stabilized 5V power supply to power Arduino Mega 2560.
May I connect it to +5V pin ? Will it not damage Arduino builtin stabilizer, or will not the stabilizer take some (significant) current ?

Arduino IDE 1.0 doesn't upload to Arduino Mega 2560.
Older versions do.
