Error while running a model on Raspberry pi

20 views (last 30 days)
I am using a raspberry pi camera for taking a continuous video for my image processing network. At first, when I tried to run my model, it worked fine. But later on when I tried to run the same model, I got error messah=ge like:
The model that you are trying to run in External mode does not match the application running on your target. Checksum test (TARGET_CONNECT) failed. The host model's structural checksum is [3952797520, 3164253609, 4022928347, 1013116400] and the target application's structural checksum is [812222564, 2062717974, 3160967008, 2531862615]. Rebuild the model, run it on your target, and start External mode simulation again. Component:Simulink | Category:Model error Unable to connect to the 'Raspberry Pi' target for 'TRIAL_2'.
Please help me out this problem ASAP. Thanks in advance.

Try the following
1) If you have made changes to your model, save the model before deploying.
2) Clean up all the files related to your model on the Raspberry Pi. Relaunch the model in External Mode.
Hope this helps.

Hello Mr. Prabhu,
How can I clean up all the files related to model on the raspberry as you mentioned on second step?
Thank you!

From your MATLAB command window, execute the following
>> mypi = raspberrypi();
>> openShell(mypi)
In the putty window which opens up, execute the 'ls' command to find out all the folders under /home/pi.
If for eaxmple, your model is named 'myModel', the there would be a folder named 'myModel' inside which all the files related to that model would exist. Delete this model by executing 'rm -rf mymodel'.
This should clean up all the files related to your model.
