I setup all tutorial of this example as the below link

https://www.mathworks.com/help/supportpkg/px4/ref/simulator-plant-model-example.html

But it show the following error.

"The base rate of the Simulink model 0 millisecond is less than 1 millisecond. This is not

supported by the PX4 Autopilot since the tick rate of NuttX OS is 1 millisecond. To fix

this error, change sample times of blocks in the Simulink model which is causing the base

rate to be 0millisecond."

I fixed this error by uncheck continuous time of some blocks. However, after I uncheck this mode, it show the error that need use mode continuous time

"

=== Simulation (Elapsed: 4 sec) ===

Error:Block 'Quad_Plant_dynamics/Quadcopter model/6DOF Rigid body dynamics /Calculate DCM &

Euler Angles/phi theta psi' uses continuous time, which is not supported with the current

configuration."

These two errors are contradictory. So, I can not fix them.

Can you help me?

are you trying to generate code for the plant model? The plant model is supposed to run on the host (by clicking run in Simulink). The code needs to be generated for the controller.
