Beeaglebone black with simulink can't handle 1kHz. I am trying with just a Led blinking example. When I put 0.001s of sample time in the model configuration panel and StopTime simulation of 10s. Looks like the BBB is taking longer than 10s to finish the code. I am also deploying the code to the hardware, not seeing any signal in "real time".

Hi Pedro,
To address the BeagleBone Black's inability to handle a 1 kHz LED blinking task with Simulink:
  • Reduce the sample rate to improve performance.
  • Use a fixed-step solver with an appropriate step size.
  • Simplify the model and use Embedded Coder for optimized code.
  • Ensure the BBB runs in real-time mode; consider using an RTOS.
  • Use hardware PWM for precise timing.
  • Verify deployment settings and use external mode for real-time monitoring.
  • Add diagnostics to log execution times and check system load.
These steps should help optimize the setup and improve performance.
