<div dir="ltr">Hi all,<br> <br>Following our previous post (<a href="http://lists.ros.org/lurker/message/20140918.011916.e0e9cd9e.en.html">http://lists.ros.org/lurker/message/20140918.011916.e0e9cd9e.en.html</a>) and the feedback we received, we make some update here in a separate thread.<br> <br>1. We use Linux kernel version 3.8.13, and PREEMPT_RT patch version 3.8.13-rt16 to generate the Debian package. They can be downloaded from the following links:<br>kernel (32-bit): <a href="http://micros.nudt.edu.cn/ros/attachments/download/6418/linux-3.8.13.tar.bz2" target="_blank">http://micros.nudt.edu.cn/ros/attachments/download/6418/linux-3.8.13.tar.bz2</a><br>patch (32-bit): <a href="http://micros.nudt.edu.cn/ros/attachments/download/6417/patch-3.8.13-rt16.patch.bz2" target="_blank">http://micros.nudt.edu.cn/ros/attachments/download/6417/patch-3.8.13-rt16.patch.bz2</a></div><div dir="ltr">kernel (64-bit): <a href="http://micros.nudt.edu.cn/ros/attachments/download/6421/linux-3.8.13.tar.bz2" target="_blank">http://micros.nudt.edu.cn/ros/attachments/download/6421/linux-3.8.13.tar.bz2</a></div><div dir="ltr">patch (32-bit): <a href="http://micros.nudt.edu.cn/ros/attachments/download/6420/patch-3.8.13-rt16.patch.bz2" target="_blank">http://micros.nudt.edu.cn/ros/attachments/download/6420/patch-3.8.13-rt16.patch.bz2</a><br> <br>2.

<div dir="ltr">Hi everyone,<div><br></div><div>A real-time host OS may be needed when one is dealing with real-time guarantees in ROS applications. To make the installation of an rt-patched Linux kernel much easier, we created two Debian packages which do most of the work. They uses the Linux 3.8.13-rt16 RT-PREEMPT patch for 32-bit and 64-bit systems, respectively.</div><div><br></div><div>If you would like to give them a try, you can download the packages from the following links:</div><div>32-bit: <a style="font-size: 12pt;" href="http://micros.nudt.edu.cn/ros/attachments/download/6409/linux-image-3.8.13-rt16-i386-v0.0.1.deb" target="_blank">http://micros.nudt.edu.cn/ros/attachments/download/6409/linux-image-3.8.13-rt16-i386-v0.0.1.deb</a></div><div>64-bit: <a style="font-size: 12pt;" href="http://micros.nudt.edu.cn/ros/attachments/download/6413/linux-image-3.8.13-rt16_3.8.13-rt16-10.00.Custom_amd64.deb" target="_blank">http://micros.nudt.edu.cn/ros/attachments/download/6413/linux-image-3.8.13-rt16_3.8.13-rt16-10.00.Custom_amd64.deb</a></div><div><br></div><div>Place the corresponding package in any directory, and then run the following command and reboot the system.</div><div><span style='color: rgb(72, 72, 72); line-height: 21px; font-family: "Source Code Pro"; font-size: 13px; background-color: rgb(255, 255, 255);'>sudo dpkg -i linux-image-XXXX.deb</span></div><div><br></div><div>Now the real-time kernel will be there.</div><div><br></div><div>We would be grateful if you can try them out and any feedback would be greatly appreciated.</div><div><div><br>Best regards,<div>Yanzhen</div><div><br></div></div></div></div>
