Hi Hocine YAKOUBI,
The error that you see in the build "Cannot identify a ROS distrubution in /opt/ros" can be worked around by executing the below commands on the pi terminal,
echo "MW_ROSDISTRO=melodic" |sudo tee -a /etc/environment
Bascially, we need to tell Simulink the version of ROS present on pi. This is currently done via setting a specific environment variable in /etc/environment file. I am guessing the environment file may be corrupted. You can check the contents of it by executing "cat /etc/environment". By running tha above cmd, we are appending the needed environment variable to the file.
Please let me know if this works.
Thanks,
Prasanth
