sudo dd if=/dev/zero of=/dev/sdc bs=1024 count=1024
Before use anyway of partition one good practise is unmount the dev where is inserted the SD. -> <code>umount /dev/sdx</code>
 
Now we are ready to create the corresponding partitions in our MicroSD Card.
* Copy MLO and u-boot.img to primary into the ''root folder'' of the '''boot partition'''
<pre>cp [your_u-boot_directory]/u.boot.img /media/user/boot cp [your_u-boot_directory]/MLO /media/user/boot
</pre>
You can follow this post [[The bootloader U-Boot|U-boot Bootloader]] if you want build the MLO and u-boot
* Copy u-boot.imx using dd before primary partition in raw mode as
<pre>sudo dd ifsudo dd if= /[your_u-boot_directory]/u-boot.imx of=/dev/ [your_sd] bs=512 seek=2 </pre>You can follow this post [[The bootloader U-Boot|U-boot Bootloader]] you want build the u-boot.imx  '''How to configure Uenv<br />''' It is need to indicate how start the boot. For this reason it will be created a file called uenv.txt with the correct configuration. We present two examples of help to start the system from the MicroSD Card or from an nfs server.
You can follow this post * If we want boot from the bootable microSD Card. [[The bootloader U-Boot|U-boot Bootloaderhttp://downloads.isee.biz/pub/relaunch/uenv.txt uenv.txt]] you * If we want build the u-bootfrom nfs server.imx[http://downloads.isee.biz/pub/relaunch/uenv_nfs.txt uenv.txt]
These two examples have an ip address assigned to them that can be modified as you want.
