The linked post seem to discuss a hardware-specific optimization, I'm interested in general solutions. But they also link to <A href="http://processors.wiki.ti.com/index.php/Sitara_Linux_Training:_Boot_Time_Reduction" title="http://processors.wiki.ti.com/index.php/Sitara_Linux_Training:_Boot_Time_Reduction">Sitara Linux Training: Boot Time Reduction - Texas Instruments Wiki</A>, which gives really a detailed explanation of how to reduce general Linux boot time - so perfect for Linux!</P><P></P><P>Anyway, I'm still also interested in the other possible solutions and would be glad for other recommendations.</P></BODY></HTML> Thu, 05 Feb 2015 08:14:10 GMT https://community.nxp.com/t5/i-MX-Processors/OS-GUI-options-for-fast-bootup/m-p/347736#M48150 kubiznak_petr 2015-02-05T08:14:10Z
