AVR-ISP not burning sketches

Hi everyone!

I've just started using an AVR-ISP to burn sketches on my arduino Uno. Problem is: it does not work. I always get the following error message:

"Serial port '/dev/ttyACM0' not found. Did you select the right one from the Tools > Serial Port menu?"

Well... the so called Tools > Serial Port menu is greyed out! I cannot select anything from there.

A few additional details:

  • I use Arduino 1.0.6
  • I was selecting AVR-ISP in Tools > Programmer, and Arduino Uno in Tools > Board
  • I have another Uno that works perfectly (but on that one I still use the bootloader), no matter what sketch I try to run. Serial port ttyACM0 is found.
  • I run Ubuntu 12.04

Any idea how I could solve that/check what's wrong?

Thanks in advance,

Best,

Alex

Perhaps you accidentally overwrite the firmware on the Atmega16U2.The Atmega16U2 is programmed as a USB-to-serial converter and if does not have the firmware correctly then you will not have a "Serial port '/dev/ttyACM0"

make ensure you choosen proper programmer. if you using avr pocket programmer then u should select

tools->programmer-> usbtinyISp

make ensure the mounting of AVR-ISP is proper .

let us error you got.

Also check your controller IC name.

for example arduino uno avilable in two version

atmega328pu ;atmega328p-pu whos signature are totally different.So it might also one reason.

Thanks for the answers!

Well I've just started using my external programmer so if I already did something wrong, that would be extremely unfortunate! I've only tried to upload a basic sketch to my Uno, nothing else... I hope I have not erased anything... But as I've never been able to send a sketch to the Uno it seems unlikely

Concerning the programmer: I bought this guy:

I was sure it was an AVR-ISP because of the title, but it actually looks like a usbtinyISP. So I selected tools > programmer > usbtinyisp and tried to upload a sketch --> got the same error "Serial port not found etc..."

My Uno is a R3 Uno with a 328P-UP chip. It used to work perfectly until I erased the bootloader and tried to burn sketch with an external programmer.

I'm a little bit concerned about the fact that the computer does not even recognize there is an ISP connected!
Any thoughts?

Best,

Alex
