After somehow I couldn´t upload any new software to my Arduino I learned how to use the Popolu USB AVR Programmer I luckily already had purchased before.
Even worse than that I didn´t immediately recognize that my software updates weren´t loaded to the Arduino, because somehow I didn´t see the upload error messages when working with the Arduino VS plugin; only in the Arduino programming software I saw those messages.

- I was getting upload verification errors
- Messages like ‘not in sync’
I still have no clue. My best guess is that I had some voltage glitches from the electronics attached to my Arduino….
Connecting Programmer with PC and Arduino
- Connect Polulu to USB (PC)
The Green light must be constantly on; anything else indicates that the PC connection doesn´t work (e.g. wrong USB driver)
- Power up Target Device (in my case Arduino Duemilanove)
- Connect ISP cable from Polulu to Target Device
The yellow led on Pololu must blink
Uploading the Bootloader to the Arduino
As the whole procedure didn´t work from the Arduino IDE, I learned to use AVRDude from the command line. As an additional hurdle, avrdude.conf was missing on my windows installation.
http://www.ladyada.net/learn/avr/avrdude.html was a great help 🙂
I then created the following batch file
Attention: be sure to use the right COMxx interface
” avrdude -p m328p -P COM2 -c avrispv2 -e -U flash:w:bootloader.hex
” avrdude options doku under http://www.nongnu.org/avrdude/user-
” my Pololu connects on COM15
” -e erases what´s been there before
” -U flash says that the flash ROM shall be written
” -v verbose
rem Geocities 🙂 LOL. Didn´t know it still exists 😉
rem COM16 !!! Argh. Cost mw 30min to find out I´d used the wrong COM 🙁
cd “C:\Program Files\ArduinoSoftware\Entwicklungsumgebung\Windows\arduino-1.0.1\hardware\arduino\bootloaders\atmega\”
\bin\avrdude.exe” -C “C:\Users\Robert\Desktop\Arduino\avrdude.conf” -p m168 -P com16 -c avrispv2 -e -v -U flash:w:ATmegaBOOT_168_diecimila.hex
As no avrdude.conf file was on my machine, I created the following avrdude.conf
Attention: This must of course fit your programmer and target device.
had errorswhen writing the bootloader to a 328p : stk500v2_command() command failed rc=-1. When using the -F option of AVRDUDE, it said the device signature was invalid:
avrdude.exe: Device signature = 0x000000
avrdude.exe: Yikes! Invalid device signature.
avrdude.exe: Expected signature for ATMEGA328P is 1E 95 0F
I then added the -B and -i options to the AVRDUDE call:
“C:\Program Files (x86)\Arduino\hardware\tools\avr\bin\avrdude.exe” -C “C:\Program Files (x86)\Arduino\hardware\tools\avr\etc\avrdude.conf” -p m328p -P
com3 -c avrispv2 -e -v -U flash:w:ATmegaBOOT_168_atmega328.hex -i 90 -B 22 -F
