I try to test a new Arduino Due from eBay. (Other customers of the same seller don't have problems.)
I have experience with Arduno Mega2560 and Nano . I work with latest Arduino IDE version 1.5.4.r2.
- I have received my old Arduinos with preprogrammed program "blink.ino" from IDE Examples (subfolder "c:\Program Files(x86)\Arduino\examples\01.Basics\Blink" ) and onboard LED on pin 13 was blinking, but now the case is not the same.
I tried to compile and load (through the program port) the same BLINK program as it is described in "Arduino DUE - 1st Look" youtube video. - With me, the test not pass neither before my attempts to reload compiled by me program, neither after that.
- During my attempt to flash my program (i.e. blink.ino) the programming LEDS on the board (RX/TX next to programming port) don't blink
- The Arduino IDE messages during programming seems OK (nevertheless of not blinking RX/TX LEDS on the board): Here are the messages:
Sketch uses 10 076 bytes (1%) of program storage space. Maximum is 524 288 bytes.

Set boot flash true
CPU reset.
But it not works (does not blink yellow onboard LED - connected to pin 13 )!
My board is not OK.
5) I wonder, if the missing or faulty bootloader may be a possible cause.
6) I have working Arduino Mega2560 and may try to use it as a programmer to reburn the Due board bootloader.
What is your opinion if you have such experience?
7) Unfortunately I have not any experience with bootloaders.
I red "Using an Arduino as an AVR ISP (In-System Programmer)" : http://arduino.cc/en/Tutorial/ArduinoISP
and "Upgrading the firmware of the Arduino Due Programming port 16U2" :http://arduino.cc/en/Hacking/Upgrading16U2Due
I am not sure that this is valid for Arduino Due.
I wont to do all possible, before unpleasant eBay returning procedure .
Please excuse my English.
Any help will be appreciated.
Thanks in advance.
