all of them.<br> First you have to learn how to make and boot a new kernel, taken form <a href=3D"http://kernel.org" target=3D"_blank" moz-do-not-send=3D"true">kernel.org= </a> and associated to any of the patches coming with your RTAI of choice. For that read the README in the LINUX kernel, with special care to the options:=C2=A0 "make localmodconfig" and=C2=A0 "make localyesconfig".<br> Once you have a LINUX .config that works, you'll remake the kernel anew, applying the related RTAI patch first and using the working .config you have.<spa= n class=3D"gmail-"><br> <br> Paolo<br> <br> <br> <br> On 02/12/2018 02:23 PM, Guo Yunfei wrote:<br> </span></div> <blockquote type=3D"cite"> <div> <div class=3D"gmail-h5"> <div dir=3D"ltr"> <div><span><br> </span></div> <div><span>Hi. everybody.</span></div> <div><span><br> </span></div> <div><span>I always install RTAI 4.0 and RTAI 4.1 on Debian as below steps and using it perfect.</span></div> <div><span>When I install RTAI 5.1 as same steps. =C2=A0the RTAI 5.1 can be make successfully.</span></div> <div><span>But the system not reponse after I test the latency by that "run " command.</spa= n></div> <div><span><br> </span></div> <div><span>Could some one give me a guide of installation of RTAI 5.1 on Debian?</span></d= iv> <div><span><br> </span></div> <div><span>Best Regards</span></div> <div><span>Guo Yunfei</span></div> <div><span><br> </span></div> <span> <div>My steps:<span><br> </span></div> <div><span>//----------------------------<wbr>-= -------------</span></div> <div>This document describes how to install RTAI 4.0 on a Ubuntu 12.04.4 LTS using a 3.8.13 kernel, either 32bit or 64 bit version.<br> </div> </span> <h4><a name=3D"m_4933134306362649551_Prerequisites" moz-do-not-send=3D"true"></a>Prerequisites</h= 4> <p>Install Ubuntu 12.04.4 using one of the following images:</p> <p><a href=3D"http://releases.ubuntu.com/precise/ubuntu-12.04.4-desktop-amd64.i= so" target=3D"_blank" moz-do-not-send=3D"true">ht= tp://releases.ubuntu.com/<wbr>precise/ubuntu-12.04.4-<wbr>desktop-amd64.i= so</a></p> <p><a href=3D"http://releases.ubuntu.com/precise/ubuntu-12.04.4-desktop-i386.is= o" target=3D"_blank" moz-do-not-send=3D"true">ht= tp://releases.ubuntu.com/<wbr>precise/ubuntu-12.04.4-<wbr>desktop-i386.is= o</a></p> <p>And then follow the installation instructions here:=C2=A0<a href=3D"https://help.ubuntu.com/community/Ins= tallation/" target=3D"_blank" moz-do-not-send=3D"true">ht= tps://help.ubuntu.com/<wbr>community/Installation/</a></p> <h4><a name=3D"m_4933134306362649551_Introduction= " moz-do-not-send=3D"true"></a>Introduction</h4= > <p>If the ROOT user is not created yet, log as your usual user, open a terminal and type -></p> <pre style=3D"color:rgb(0,0,0)"># sudo su - # sudo passwd root </pre> <p>Enter the password for the ROOT user.
