How do I synchronize PTP clocks between two Speedgoat target computers?

Can you give me an example for clock synchronization between two Speedgoat target computers using PTP?

For MATLAB R2020b and later:

PTP functionality is provided by the Blackberry QNX real-time operating system which is used by Simulink Real-Time. See the QNX documentation to learn more about the PTP daemon and flags: ptpd, ptpd-avb (qnx.com)

See the following prerequisites for enabling PTP on an Ethernet interface: 

PTP Prerequisites - MATLAB & Simulink (mathworks.com)

The following example shows how to sync PTP clocks on two Speedgoat machines:

The example files were added in R2023a, but the same commands and principles should work in any release starting from R2020b.

 

For MATLAB R2020a and earlier:

Please follow the Simulink Real-Time example below:
