[[Image:Gparted boot flag.png|thumb|center]]Now we have the microsd prepared for copy the boot files
==Boot Partition StructureMLO + u-boot IGEP Boards Texas Instruments based boards==We commented in the theory point the OMAP needs only After build or download the MLO (xand u-loader) file for boot, we will start checking this point.you should follow the next steps:
Before you follow the next points you should mount the microsd * Copy MLO and u-boot.img to primary boot partition in your host pc.
Select $ cp MLO u-boot.img /media/user/bootYou can follow this [[U-Boot Texas Instruments Series|HowTo]] if you want build the MLO and u-boot partition and mount it in your host.
[[Image:Microsd partitions==u-boot.png|thumb|center]]imx IGEP Boards based on NXP-Freescale Processors==* Copy u-boot.imx using dd before primary partition in raw mode as
sudo dd if=/home/user/u-boot-imx/u-boot.imx of=/dev/sde bs=512 seek=2
Where /dev/sde is your microsd card
==X-Loader (MLO) - IGEPv2 - IGEP COM Module - IGEP COM Proton==You can follow this other howto about the [[The IGEP X-loader|IGEP-X-loader]]. <pre>We will compile the sources and get it from our git repository: $/home/jdoe> git clone git://git.isee.biz/pub/scm/igep-x-loader.git $/home/jdoe> cd igep-x-loader $/home/jdoe/igep-x-loader> make igep00x0_config CROSS_COMPILE=<put here your cross compiler> $/home/jdoe/igep-xU-loader> make CROSS_COMPILE=<put here your cross compiler> Starting from version 2.5 it's not necesary sign the MLO due the build system generate directly the MLO fileif you're using a old version then you must sign it as: $/home/jdoe/igep-x-loader> contrib/signGP</pre>Alternatively you can download the binary package from [http://downloads.isee.biz/pub/releases/IGEP_xloader/igep-x-loader-2.5.0-2.tar.bz2 here] If you're using 2.5.0.x x-loader copy directly the MLO to your boot partion or if you use older version then follow the next instructions: Copy the xFreescale-loader.bin.ift into the boot partition. [[Image:Copy Xloader.pngNXP iMX6 Series|thumb|centerHowTo ]] Rename the x-loader.bin.ift to MLO [[Image:Rename Xloader to MLO.png|thumb|center]]Now we're ready for test the board boot from the microsd card. ===X-Loader Boot===We will eject the boot and rootfs partitions from our Host PC, this step it's a lot important due the Linux must sync all changes before eject the microsd card. We will insert our microSD card into the IGEP board, connect the serial debug cable and open the serial terminal [[Image:Putty Serial Configuration.png|thumb|center]]Power UP the board.

==Kernel==
You can follow this other howto about [[The Linux kernel|how compile and install the Linux Kernel]].
We will get from our git repository the kernel sources and build it:
<pre>a) Clone the Kernel git repository
$/home/jdoe/> git clone git://git.isee.biz/pub/scm/linux-omap-2.6.git
$/home/jdoe> cd linux-omap-2.6
b) Checkout your desired branch (we used for this howto 2.6.37.y IGEPv2, IGEP COM Module and IGEP COM PROTON)
if you're using IGEP COM Aquila or IGEPv5 you must select your right branch:
IGEPv5: linux-3.8.y-omap5
IGEP COM Aquila: linux-3.8.y-am335x
$/home/jdoe/linux-omap-2.6> git checkout origin/linux-2.6.37.y -b linux-2-6-37.y
c) Configure the kernel (IGEPv2, IGEP COM Module, IGEP COM Proton)
$/home/jdoe/linux-omap-2.6> make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- igep00x0_defconfig
If you use IGEPv5 or IGEP COM Aquila you should use:
$/home/jdoe/linux-omap-2.6> make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- omap2plus_defconfig
d) Build the kernel and Modules (IGEPv2, IGEP COM Module, IGEP COM PROTON)
$/home/jdoe/linux-omap-2.6> make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- zImage modules
e) Build the kernel, modules and dtbs (IGEPv5, IGEP COM Aquila)
$/home/jdoe/linux-omap-2.6> make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage modules dtbs
</pre>
Notes: The kernel binary resides inside the directory: $/home/jdoe/linux-omap-2.6/arch/arm/boot/'''zImage''' <br />
Notes: Alternatively you can download the kernel binary from this [http://downloads.isee.biz/pub/releases/linux_kernel/v2.6.37-7/zImage-2.6.37-7.bin link] and modules from [http://downloads.isee.biz/pub/releases/linux_kernel/v2.6.37-7/modules-2.6.37-7.tar.gz this].<br />
Notes: You can download directly all releases using this [http://downloads.isee.biz/pub/releases/linux_kernel link]<br />
Notes: Kernel 3.8.y use dtb file for describe the board configuration, these files resides inside the directory: $/home/jdoe/linux-omap-2.6/arch/arm/boot/dtbs/ and you must copy the right dtb for your board.
