Hi Andrew and Artem,<br>
Per your suggestion, I try to enable SELinux with Yocto SELinux layer(<a href="http://git.yoctoproject.org/cgit/cgit.cgi/meta-selinux" target="_blank">http://git.yoctoproject.org/cgit/cgit.cgi/meta-selinux</a>) and 64MiB flash part.<br>
But encountered one problem which is when I use command "getenforce" to check SELinux mode, it always returns "Disabled" even if SELinux mode in config file '/etc/selinux/config' is permissive or enforcing by default.<br>
<br>
Please help to advise it. <o:p></o:p></span></p>
