In the following paragraphs we will explain how to get or build those binaries to be combined in a single binary to be flashed in the bootable storage device.
=== Instructions Prepare environment === 
It is assumed that the development environment has been set up properly as described [[DESK-MX8M-L#Quick_start_guide|here]].
* start the Linux development VM and login into the system
* open a terminal window and ''cd'' into <code>desk-mxmx8-lmkimage</code> directory
<preclass="workstation-terminal">dvdk@vagrant:~$ cd desk-mx-l/desk-mx8-mkimagedvdk@vagrant:~/desk-mx-l/desk-mx8-mkimage$
</pre>
=== Clone * in case of needs you can update your local repository with the repositories ===following git command* clone ''recursively'' the Boot repositories
<pre class="workstation-terminal">
dvdk@vagrant:~/desk-mx-l$ git clone --recursive git@git.dave.eu:desk-mx-l/desk-mx8-mkimage.$ git -b desk-mx8m-l-2.0.0Cloning into 'desk-mx8-mkimage'...remote: Enumerating objects: 57, done.remote: Total 57 (delta 0), reused 0 (delta 0), pack-reused 57Receiving objects: 100% (57/57), 7.14 KiB | 7.14 MiB/s, done.Resolving deltas: 100% (28/28), done.dvdk@vagrant:~/desk-mx-l$ pull
</pre>
* update configure the submodule (i.e. sync the sub-repositories)build environment 
<pre class="workstation-terminal">

In case of ca=== Build U-certificates failures, which may appears during https access Boot === First step is to some repobuild U-Boot binaries:the same instructions can be found in the dedicated [[DESK-MX8M-L/Development/Building_U-Boot | wiki page]]

a possible solution is to disable * select the SSL verification setting:proper <code>defconfig</code> and start the ''make'' compilation

</pre>
=== Build U-Boot ===
First step is to build U-Boot binaries: the same instructions can be found in the dedicated [[DESK-MX8M-L/Development/Building_U-Boot | wiki page]]
<pre>
cd u-boot-imx
</pre>
* select the proper <code>defconfig</code> and start the ''make'' compilation
<pre>
make imx8mp_mito8mplus_defconfig
make
</pre>
This steps produce the <code>u-boot-spl.bin</code> and <code>u-boot.bin</code> files used at the last step.
 
<pre class="workstation-terminal">
dvdk@vagrant:~/desk-mx-l/desk-mx8-mkimage/u-boot-imx$ ls -la spl/u-boot-spl.bin
