Here's a small tutorial on how you can use an Arduino board to program a KK2.0 board or your ESCs.

All you need is an Arduino board and a few connecting wires.

Step 1: Burn the ArduinoISP code onto your Arduino board. The instructions for the same are given at: http://arduino.cc/en/Tutorial/ArduinoISP

Step 2: Connect your Arduino board to your KK2.0 board/ESC. Basically you have to connect the MOSI of Arduino to MOSI of board, MISO of Arduino to MISO of board, and so on for SCK, RST, VCC, GND.

Diagrams for the pinouts are attached.

Step 3: Download the latest version of avrdude from: http://download.savannah.gnu.org/releases/avrdude/

A short tutorial on avrdude is given here: http://www.ladyada.net/learn/avr/avrdude.html

Once you have downloaded avrdude. Open command prompt by typing 'cmd' at RUN. Go to the directory of the downloaded avrdude by using 'cd' command and then type 'avrdude' to open the program.

Step 4: Once your avrdude is ready to burn the code, check whether the connection between the boards is alright by typing the command:

avrdude -P COM4 -b 19200 -c avrisp -p m324pa -v -F

COM4 represents the serial port at which your Arduino board is connected to your computer. You would have to change it according to your computer. If all goes well, you would get a similar output:




Having done this, you can go ahead and finally burn the KK2.0 code onto your KK board. The latest firmware can be found at: http://www.rcgroups.com/forums/showpost.php?p=23209042&postcount=6371

You would have to copy the HEX file and paste it into your avrdude folder.

The command to burn the code is:

avrdude -P COM4 -b 19200 -c avrisp -p m324pa -v -e -U flash:w:kk2.hex:i

You would get this output:



You would notice that the display on your KK2.0 board changes during the code is being burnt. Once the procedure is completed, the board will automatically restart and you would notice that the new firmware has been installed.  :thumbsup:

I used the procedure to update my KK2.0 board, but I'm pretty sure you can use it change the firmware for your ESCs too.  ;D

Warning – It is possible to ruin your board while attempting this process.  :P

Great work buddy   :thumbsup:

Hello jaspreet.guitar,

I am brand new to AVR programming. I found your post very informative, but I am confused on 1 point. When you download the file "avrdude-5.11svn-20111019.tar.gz" from http://download.savannah.gnu.org/releases/avrdude/ where is the executable? I see that there is an avrdude.conf.in file that contains the 324pa configuration, but I do not know what is supposed to run from the command line. Any help would be appreciated!

note: I am on a Windows machine

That .tar.gz is just the source code, which you have to compile with some kind of compiler (like Visual C++ in Microsoft Visual Studio) to make the executable.

Seems like you have to use the precompiled version, like WinAVR from here :

http://sourceforge.net/projects/winavr/
http://sourceforge.net/projects/winavr/files/WinAVR/20100110/  (this seems to be the latest).

To get avrdude for Windows, either get hold of WinAVR or build from source. Since you're beginning, I'd suggest use WinAVR. Once setup, edit you path variables so it points to the WinAVR installation directory. More information here:

http://www.nongnu.org/avrdude/user-manual/avrdude_19.html

May be we should edit the first post to clear this confusion.  Something like "If you are Windows, get WinAVR from .....".

Thank you for the suggestions. As far as I can tell, WinAVR has an older version of avrdude that does not have the configuration for the 324pa board on the KK2.0. I will try compiling from source and see how it goes

Success!

In case there are other beginners trying to do this, I will share the tricks I used.

If you try using an Arduino Leonardo like I did, please follow the suggestions by PeterVH: http://petervanhoyweghen.wordpress.com/2012/09/16/arduinoisp-on-the-leonardo/

Instead of trying to compile the source code myself in Windows, I ended up using WinAVR, even though the version available on SourceForge does not use the newest version of avrdude (5.10 instead of 5.11svn). To get around this, I simply downloaded the uncompiled code for version 5.11svn from savannah.gnu, opened the file "avrdude.conf.in" and searched for the part definition for the ATmega324PA. I then copied and pasted this section into the "avrdude.conf" found in the \bin directory where WinAVR was installed.

Thanks to everyone for your help!!!

congratulations

Hi there,
this workaround doesnt work for me. I have an arduino uno with a 328P on it so i have to change the command to avrdude -P COM4 -c arduino -p m328p -v -e -U flash:w:kk2.hex:i

The answer of the command window is:

C:\kkflashtool\lib\avrdude\windows>avrdude -P COM4 -c arduino -p m328p -v -e -U
flash:w:kk2.hex:i

avrdude done.  Thank you.

And you see, the transfer of the data takes 5.31 s and not 31.86 s. I think my arduino isnt transfering the data to the KK board...

Could anyone help me out with that?

I found the fault - i used a 10 µF Capacitor instead of a 22 µF Capacitor between RST and GND. Now it works flawlessly.

Dear Japreet
after the command

avrdude -P COM4 -b 19200 -c avrisp -p m324pa -v -F

I am getting
