The reason for this is that the "CAN Log" block is intended solely for host-based analysis and does not support code generation for deployment to target hardware.
As a workaround for logging signals on targets such as Arduino and Rasperry Pi, consider using "Simulink Data Inspector" while running the model in the "Model and Tune" mode.
First, instead of clicking on "Build, Deploy and Start", instead select the "Monitor & Tune" mode. This deploys the model and communicates with the deployed model on your hardware board during runtime.
For more information on this step, please refer to the documentation on signal monitoring and parameter tuning.
Next, to enable Simulink Data Inspector, you can select a signal and click the Wi-Fi icon that appears:
For more information on this step, please refer to the following documentation on data logging.
