How do I get rid of this error message?

Hello,

I am currently following the SITL example to deploy my model to px4 but keep getting this 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."

Please, how do I resolve this? How do I locate blocks having 0 milliseconds? I have followed the solution given in a somewhat related post on this community but not working in this case.

Thank you.

Hi,

The error message you're encountering suggests that the base rate of your Simulink model is set to 0 milliseconds, which is not compatible with the PX4 Autopilot since its tick rate is 1 millisecond. To resolve this issue, you need to locate the blocks in your Simulink model that have a sample time of 0 milliseconds and change them to a non-zero value.

Hello @Shaik,

Thank you. Please, how do I locate the blocks having a sample time of 0 milliseconds? I am using Matlab 2022b.

In MATLAB 2022b, you can use the Model Advisor to locate blocks that have a sample time of 0 milliseconds in your Simulink model.
