Setup
You can run the multiple measurements sample with command-line options to see how it uses the measurement library. This guide provides examples of commands and outputs. Before attempting to run the sample, make sure you have completed the following prerequisites.
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.
- From your host system, connect to the target system:ssh <user>@<target>
- In the SSH session, run the following command to runtcc_rt_checker:tcc_rt_checker
- In the output, find theRT Kernel Checkerrow and confirm that it containsRT_READY.+-----+-------------------+--------------------------+----------------------+----------+ | 4 | RT Kernel Checker | Checks that RT kernel is | Current kernel is RT | RT_READY | | | | used | | | +-----+-------------------+--------------------------+----------------------+----------+
- If theRT Kernel Checkerrow does not reportRT_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.
For systems running the PR1 release of the Yocto Project*-based BSP for Intel Atom® x6000E Series processors, you must take additional steps to build samples on the target system:
- Go to the sample directory:cd /usr/share/tcc_tools/samples/<sample_name>
- Change the library name in the Makefile to libittnotify64.a:sed 's/ittnotify/ittnotify64/g' -i Makefile
