'''Note:''' Starting from this '''DESK-MX8M-L-2.0.0''' release the support for the SPL has been introduced in UbootU-Boot. Previous versions of this script will no longer produce a fully functional and bootable microSD card. <br>

The procedure has been tested on a Linux PC running Ubuntu LTS (>=16MVM released with '''DESK-MX8M-L 4.0.04) distribution 0''' release with *a 16 32 GB microSD card [1]*a USB SD card reader*the binary files delivered along with the [[DESK-MX8M-L/General/Release_Notes#Downloadable_binary_imagesDownloadable_binary_images_3|DESKMX8MDESK-MX8M-L 24.0.0]].

The script - named <code>mksddesk-mx8m-l-4.0.0_mksd.sh</code> - can be realized with the following code: <preclass="workstation-terminal">

Here is an example that shows how to use this script. Let's assume that the binary We use here files were downloaded in the <code>sdcard<delivered with [[DESK-MX8M-L/code> subdirectory of the working directoryGeneral/Release_Notes#Downloadable_binary_images_3|DESK-MX8M-L 4.0.0]] release. Before invoking the script, the following files has to be renamed in order to make them compatible with the default U-Boot environment variables:

* Device tree blob: <code>imx8mp-mito8mplus-cb1008.dtb</code> or <code>imx8mm-mito8mmini-cb100a.dtb</code> Let's start with creating <code>boot.scr</code>. On MVM there is <code>/home/dvdk/desk-mx-l/desk-mx8m-l-4.0.0_bootscript.txt</code> file that we can use to create needed file. Here below there is an example on how to create a <code>boot.scr</code> file from the '''desk-mx8m-l-4.0.0_bootscript.txt''' for booting from SD card: <pre class="workstation-terminal">echo 'bootscript generated with command "mkimage -A ARM -T script -C none -n DESK-MX8M -d bootscript.txt boot.scr"' setenv desk_release 'desk-mx8m-l-4.0.0' if test 0x${cb_configid#} = 0x00001001;then setenv fdtfile imx8mp-mito8mplus-cb1001.dtbelif test 0x${cb_configid#} = 0x00001004;then setenv fdtfile imx8mp-mito8mplus-cb1004.dtbelif test 0x${cb_configid#} = 0x00001005;then setenv fdtfile imx8mp-mito8mplus-cb1005.dtb # CM7 boot setenv cm7_loadaddr 0x48000000 setenv cm7_tcm_start 0x7e0000 setenv cm7_boot 'fatload mmc ${sd_dev}:1 ${cm7_loadaddr} stress_m7.bin;cp.b ${cm7_loadaddr} ${cm7_tcm_start} 20000; bootaux ${cm7_tcm_start}'elif test 0x${cb_configid#} = 0x00001008;then setenv fdtfile imx8mp-mito8mplus-cb1008.dtbelif test 0x${cb_configid#} = 0x0000100a;then setenv fdtfile imx8mm-mito8mmini-cb100a.dtbelse echo Invalid CB ConfigID!
