Arduino Uno R3 SMD Edition: Uploading Issue

Development Tools IDE 1.x
1

Hi everybody! :slight_smile:
I bought a new Arduino few days ago (Arduino Uno R3 SMD Edition, ATmega16u2 for communications, ATmega328P-MU as microcontroller) and when i plugged it for the first time to the PC i noticed my board wasn't programmed with bootloader (led "L" didn't blink on power on). I did few researches and, as explained in the tutorial, I used another Arduino Uno R3 as an ISP programmer (with ATmega328P-PU no smd). I burnt the bootloader and now the led "L" blinks 3 times, then it stays on with the "ON" led.
So i tried to test the "Blink" sketch, but when uploading, led "L" blinks few times, then led "RX" blinks 3 times, i wait few seconds, and the ArduinoIDE console says

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

The COM port is the right one, even the selected board, I have Win7 (x64) and I have successfully installed the drivers. Somewhere i read i have to push RESET button just before uploading, i did and it didn't work.
I also tried the DFU programming, I installed FLIP and uploaded the firmware "Arduino-usbserial-atmega16u2-Uno-Rev3", with no success.
I reinstalled everything, I used different USB wire and USB port, I rebooted Windows, but it didn't work anyway. =(

My questions are:

  1. Have I used the right Arduino as ArduinoISP?
  2. Does DFU-programmer actually program the board?
  3. Did i brick my Arduino using the wrong bootloader?

Thanks for answers!

The solid LED may not indicate an actual issue. The R3 uses an op-amp circuit to light the LED which occasionally gets stuck on.

The next thing to try would be the loopback test to verify your computer is communicating correctly. Instructions are found at the top of this forum.

Ok, I will give it a try soon :slight_smile: what happens if the test fail?

[EDIT] OK! The loopback test works fine! :smiley:

Is it a good try burning the optiboot bootloader? Maybe default bootloader doesn't work well...

The bootloader included with 1.0.5 should be the latest. Couldn't hurt to try others.
