View source for UDOO kernel update procedure

[[Category:UDOO]]
Updating UDOO's kernel ensures you're aligned with latest Official build of UDOO Kernel Unico. This kernel is developed to suit a general purpose system, so it is the suggested kernel for UDOO Board.

==On UDOO Board with internet connection==

If you have access to a wifi or an ethernet connection download the update package directly on UDOO running UDOOUbuntu.
Turn on your UDOO following the [[http://www.elinux.org/UDOO_Getting_started|Getting Started Guide]] 

Once the OS has booted open a terminal and type the command:

 wget http://download.udoo.org/files/udooupdate.tar.gz


==On UDOO board without internet connection==

If you don’t have any internet connection on UDOO, you can download the package on your computer from the UDOO website:

 http://download.udoo.org/files/udooupdate.tar.gz

Copy the package on a USB pen drive.
When Ubuntu OS on UDOO is ready insert the usb pen and copy the update file in the home folder.

==Update Procedure==

*Open the terminal and extract the package using the command:


 tar -xzvf udooupdate.tar.gz

*Navigate into the folder you just created:


 cd udooupdate

*run the script as administrator replacing –cpu option value with the cpu type of your board [dual,quad] e.g.:

FOR QUAD
 sudo ./udooupdate.sh --cpu=quad

FOR DUAL
 sudo ./udooupdate.sh --cpu=dual


This script basically copy the new U-boot image and Kernel image on SD. Once the update has finished reboot the UDOO board using the command:

 sudo reboot

Done.
