Arduino uno v3 not load any program.
avrdude: stk500_getsync(): not in sync: resp=0x00
Green and orange led always light. Push Reset button not blink any led.
The RX and TX led is no flashing.
echo test not work.
Windows xp view is "arduino uno" on com 12
Dead 328P-PU or 16u2 ?
If loop back is failing and pin 13's LED never blinked, return it.
"return it" ? its total dead board?
Return to shop?
Or something I could not understand? My English is not very good.
Yes, return to shop. Why waste more time troubleshooting? It arrived broken.
Thanks.I buy new arduino, but try restore this board.
are you using arduino IDE 1.0 or above? try switching to 0023 see if it works
ttttkk,try old version IDE, no changes.
If burned 16u2, the computer did not specify how Arduino uno in Device Manager. Am I correct think?
Could there be a problem in 328P-PU?
I can replace it if I buy this chip.
I'm pretty sure I blew my ATmega328 on the Arduino Uno R3.
I bought pre-programmed chip from Adafruit and got the same error...until I read the website:
Be sure to select "DUEMILANOVE with ATMEGA328" in the Arduino IDE
Be sure to select "DUEMILANOVE with ATMEGA328" in the Arduino IDE
Be sure to select "DUEMILANOVE with ATMEGA328" in the Arduino IDE
Be sure to select "DUEMILANOVE with ATMEGA328" in the Arduino IDE
Be sure to select "DUEMILANOVE with ATMEGA328" in the Arduino IDE
yes even with the UNO. Be sure to select "DUEMILANOVE with ATMEGA328" in the Arduino IDE
hope this help. I know I didn't find a solution very easily, well at least not very quickly!!!!
go to \hardware\arduino\boards.txt, find this line "uno.name=Arduino Uno uno.upload.protocol=arduino", replace the protocol=arduino to =stk500.
I don't know if it works on Uno, but it did save me from similar issue with Duemilanove.
By the way, did you install the Uno driver?
Inverse chip replacement is another case. Check Atmega328 replacement.
I have had the same error, nothing worked. Tried almost every option mentioned.
But the solution for me was simple. I have Windows 7 64-bit.
First remove all drivers and everything wat looks likes al (virtual) USB to COM port driver.
Reboot (its Windows)
Install the right drivers from the Arduino IDE drivers\ map, in my case the 64-bit drivers.
Go to http://www.ftdichip.com/Drivers/VCP.htm make the right choice for your OS and install.
Reboot (not asked but he its Windows)
Then I connected the Arduino en tried to upload the Blink-sketch.
And everything worked as expected.
Thank you, DirkLuijendijk. Yes, this was indeed the issue. You have saved me hours of debugging.
