hello folks.

first post here and first time holding something called "arduino" in my hands.

so. just finished soldering my project. i´m about to build my own chronome

http://flipmu.com/work/chronome/

and can´t figure out what i´m missing here.

here is what i´m have done so far:

http://flipmu.com/work/chronome/changing-the-serial-number/

had no problems thru steps 1-12

now, when putting (or actually trying to put) my mega 2560 R3 into DFU Mode, i get following results.
there is a little yellow LED which blinks just another couple of times after released the green pads (see pic in link) and then turns off.

open up arduino, tools/serial ports -> my arduino is no longer is the device list, which is a good sign that my 2560 is in dfu mode.

now, when typing in termial:

sudo make dfu

i get this result:
dfu-programmer at90usb82 erase
dfu-programmer: no device present.
make: *** [dfu] Error 1

what am i doing wrong?

any help highly appreciated.

greetings to all.

The Mega 2560 R3 uses the Atmega16u2 for serial conversion.

You will need to update the dfu programmer to recognize the Atmega16u2 part.

The following post discusses the steps to patch the dfu programmer:

hi louis,

thanks for the quick help.

just downloaded libusb-1.0.8 from here

http://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.8/libusb-1.0.8.tar.bz2/download.

after typing in terminal

./configure

i get this error:

hi louis,

o.k lets go on step back.

i think @dhunt has the solution

"...


Ah yes, dfu-programmer 0.5.4 does not know about the atmega16u2 and the developers don't seem to have updated it yet.

Download the dfu-programmer source from http://sourceforge.net/projects/dfu-programmer/files, apply the attached patch and build your own:
Code:
tar xzf ~/Downloads/dfu-programmer-0.5.4.tar.gz
cd dfu-programmer-0.5.4
patch -p0 < ~/Downloads/atmega16u2.diff

# Make sure you have the tools needed to build it
sudo apt-get install build-essential libusb-1.0-0-dev

# configure and build it
./bootstrap.sh
./configure
make

# install it
sudo make install

"""

this is the error i get when trying to install libusb:

Claudio-MacBook-Pro:dfu-programmer-0.5.4 claudiobattista$ sudo apt-get install build-essential libusb-1.0-0-dev
Password:
sudo: apt-get: command not found


seems like i dont have the tool i need?!

[Reply #5 on:]

I suggest you follow the steps that @dhunt suggests further down in the thread.
@dhunt used macports as the package manager to get the necessary packages.

I got the dfu-programmer to build on OSX Lion 10.7.3 with the following steps:

Install Xcode 4.3 from the Appstore
Install Xcode command line tools from Xcode preferences (see https://developer.apple.com/library/ios/#documentation/DeveloperTools/Conceptual/WhatsNewXcode/Articles/xcode_4_3.html).
Tell Xcode where Xcode is installed: sudo xcode-select -switch /Applications/Xcode.app
Set up a link for the missing clang executable: cd /Applications/Xcode.app/Contents/Developer/usr/bin; sudo ln -s clang llvm-gcc; cd -
Install macports from http://www.macports.org/
Install autoconf tools via macports: sudo port install pkgconfig automake
Install libusb via macports: sudo port install libusb-devel
Configure and build dfu-programmer: cd dfu-programmer-0.5.4; ./bootstrap.sh; ./configure; ./make; ./sudo make install

[Reply #6 on:]

just tried.

after ./configure i get this error

[Reply #7 on:]

Attached is the patched version of dfu-programmer that I built on my system...

[Reply #8 on:]

hi louis.

sorry for the dump question, but i have no idea where to put your attached file and which command to type in terminal...

thanks.

[Reply #9 on:]

You can use the instructions at the following link as a guide:

http://arduino.cc/en/Hacking/DFUProgramming8U2

Put the dfu-programmer file that you downloaded in any folder of your choosing.

Download the following file and put it in the same folder:
https://github.com/arduino/Arduino/blob/master/hardware/arduino/firmwares/arduino-usbserial/Arduino-usbserial-atmega16u2-Mega2560-Rev3.hex

Then open the terminal and cd to the folder you just put the files in and execute the following commands:

sudo ./dfu-programmer atmega16u2 erase

When this command is done and you get a command prompt again, type

sudo ./dfu-programmer atmega16u2 flash Arduino-usbserial-atmega16u2-Mega2560-Rev3.hex

Finally, type

sudo ./dfu-programmer atmega16u2 reset

[Reply #10 on:]

did so.

The ./ is used to make sure you execute the dfu-programmer app that is in the local directory.

When you removed the ./ , you are executing the old dfu-programmer app that does not have the patch.

If you look at the dfu-programmer file in Finder does it have an icon that shows "exec" and has a Kind of Unix Executable File?

If not, you will need to execute the command: chmod +x dfu-programmer

This will let you execute the file.  Make sure your terminal's local directory is the one with the downloaded dfu-programmer and hex file.
Make sure you use the ./ when you execute the commands.

[Reply #12 on:]

the dfu-programmer file didn´t had any exec icon until i did

chmod +x dfu-programmer

now my dfu-programmer file has an exec icon (see picture attached)

now, when i´m typing sudo ./dfu-programmer atmega16u2 erase

i get this:

Claudio-Battistas-MacBook-Pro:chronome_v2 claudiobattista$ sudo ./dfu-programmer atmega16u2 erase

what am i doing wrong?

[Reply #13 on:]

Now it is telling you that libusb library is not installed or it can't find it.

Since you have macports installed from a previous step, you need to run:

sudo port install libusb

Hopefully that will fix up your libusb library install.
