Setup

You can run the Ethernet timestamps sample with command-line options. This guide provides examples of commands and outputs. Before running the sample, make sure you have completed the following setup.

Prerequisites

This guide is based on a host-target setup. Confirm that you have a host system and a target system that are configured according to the Get Started Guide.

Confirm Real-Time Kernel

Confirm that the target system is running the real-time kernel.
  1. From your host system, connect to the target system:
    ssh <user>@<target>
  2. In the SSH session, run the following command to run
    tcc_rt_checker
    :
    tcc_rt_checker
  3. In the output, find the
    RT Kernel Checker
     row and confirm that it contains
    RT_READY
    .
    +-----+-------------------+--------------------------+----------------------+----------+
|  4  | RT Kernel Checker | Checks that RT kernel is | Current kernel is RT | RT_READY |
|     |                   | used                     |                      |          |
+-----+-------------------+--------------------------+----------------------+----------+
  4. If the
    RT Kernel Checker
     row does not report
    RT_READY
    , reboot the target system and make sure to select the RT kernel.

Build the Sample

The Intel® TCC Tools package for the target system contains a prebuilt binary of this sample. The binary is configured to run from any directory on the target system.
If you want to build the sample, use the provided makefile.

Run the Sample

After completing the setup, run the sample:
