Error downloading Simulink Model to Arduino Mega 2560 Rev3

Hi,

I'm using Matlab 2013a (on a Windows 8 64-bit PC) with Arduino support package 3.0. Downloading models to an Arduino UNO is wokring without problems. But I can't download any model to a new Arduino Mega 2560 Rev3. Tested with the arduinomega2560_gettingstarted model. When Simulink says "Downloading.." RX/TX LEDs are just blinking twice and I get the following error:

_The call to realtime_make_rtw_hook, during the after_make hook generated the following error: Could not download the model to the target hardware. Verify the connection between the computer and target hardware.

The build process will terminate as a result.

Caused by: Could not download the model to the target hardware. Verify the connection between the computer and target hardware._

But the target is definitely connected, and downloading programs with Ardino IDE is working fine. I've also tested this on a different PC with Windows 7 with the same result. Can anyone give me a hint please?

Thanks to the MathWorks support team, I reported this problem and they found a working solution (at least in my case):

1. Shutdown MATLAB

2. Go to the folder inside the Arduino Mega support package (by default this should be in

c:\MATLAB\SupportPackages\R2013a\arduinomega2560\+realtime\+internal)

Note : This is the location which the user installed the support package for Arduino.

3. Make a backup of the existing file "toolsInfoDataArduinoMega2560.p"

4. Overwrite the file "toolsInfoDataArduinoMega2560.p" with the attached P-file (unzip first).

5. Restart MATLAB and execute "rehash toolboxcache"

6. Try the code generation and deployment for the boards in question and verify functionality

I have the same problem in Matlab 2012b (on a Windows 7 32-bit PC) and want the attached P-file "toolsInfoDataArduinoMega2560.p". How do I get it?

please Arne i need that file >> my email : [e-mail] thanx very much :)

[RISHEEK]

please Arne or zaid_mka i need that file ;MY EMAIL : [e-mail] ,It would be of great help

Ok, here is the file again.

Hi, I am using Matlab 2013b on Mac OS 64bit, and I have the same problem of connection of the Arduino2560 R3. I couldn't find the file toolsInfoDataArduinoMega2560.p in the Matlab folder, I think because that file exists in the older versions of the Arduino support package. I have the last one, just downloaded from Mathworks Arduino Package Support. Is there another file or another way to solve my connection problem?

Thank you,

Andrea

Hello all;

I have used this procedure and the external mode does work with certain very simple models. For example an analog input>double conversion>Embedded function for a y = u(5/1024); voltage conversion> scope combination works flawlessly.

However, as soon as I add another analog input, I get the same error as sri. The minimum not working example is two analog inputs with two scopes. The exact procedure goes like this: the building process is successful, and it says " Model Successfully Downloaded to Arduino Mega 2560 ". But then, upon trying to connect to the board, the process hangs at " Initializing " and after a while I get " Error occurred while executing External Mode MEX-file 'ext_serial_win32_comm': Timed-out waiting for first connect response packet. " I've also tried to run a simple embedded function with an extended Kalman filter inside (no inputs or outputs on Arduino) and a scope, but the same thing happened.

Details:

• MATLAB Version: 8.0.0.783 (R2012b)
• Operating System: Microsoft Windows 7 Version 6.1 (Build 7601: Service Pack 1)
• Java Version: Java 1.6.0_17-b04 with Sun Microsystems Inc. Java HotSpot™ 64-Bit Server VM mixed mode
• Board: Arduino Mega 2560
• Fixed Step Discrete Solver (tried 1, 0.1 sec)
• External mode enabled.
• Baud rates 9600
• Overrun detection enabled, on pin 13
• Computer Lenovo ThinkPad T410i

Any help would be much appreciated.
