This article shows how to create a bootable microSD for the [[DESK-MX6UL-L/General/Release_Notes_(DESK-MX6UL-L)Release_Notes|DESK-MX6UL-L Release Notes]] kit by using a simple bash script. <br>'''Note:''' Note: Starting from this '''DESK-MX6UL-L 1.0.1''' 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-MX6UL-L 4.0.04) distribution 1''' release with *a 16 32 GB microSD card [1]*a USB SD card reader*the binary files delivered along with the [[Axel_Embedded_Linux_Kit_(XELK)DESK-MX6UL-L/General/Release_Notes#Downloadable_binary_imagesDownloadable_binary_images_3|DESK-MX6UL-L 14.0.10]]The resulting card is partitioned as depicted [[Axel_Embedded_Linux_Kit_here below: * bootable partition (mmcblk0p1, vfat) containing:** binary images (U-Boot and kernel images)* root file system partition (XELKmmcblk0p2, ext3)#XELK_microSD_Layout|here]]** root file system binaries and init scripts

The script - named <code>desk-mx6ul-l-1.0.0_mksdmksd.sh</code> - looks like thiscan be realized with the following code:

#!/bin/bash if [[ -z $1 || -z $2 || -z $3 || -z $4 || -z $5 ]] then echo "$0 Usage:" echo " $0 <device> <u-boot.img> <SPL> <binaries directory> <rootfs tar.bz2>" echo " Example: $0 /dev/sdc u-boot.img SPL binaries/ rootfs.tar.bz2" exit

then echo "you must be root to run this script!" exit

then echo "$1 is not a valid block device!" exitfi

then echo "Incorrect u-boot.img location!" exit fi if ! [[ -e $3 ]] then echo "Incorrect SPL location!" exit

echo "Incorrect Binaries location!" exit fi

if ! [[ -f $5 ]]

echo "Incorrect rootfs location!" exit fi

if [[ "$DRIVE" == *"mmcblk"* ]] then echo "You're using a mmc device, I need to fix partition names" PART="p"else PART=""fi UBOOT=$2

BINARIES=$4 RFS=$5

read ans

exit

{ echo 40,1380,0x0c,* echo 1420,,83,- } | sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE

Here is an example that shows how to use this script. Let's assume that the binary files were downloaded in the We will copy them into <code>~/desk-mx-l/desk</code> subdirectory of the working directory. Before invoking the script, the following Needed binary files has to can be renamed in order to make them compatible with the default U-Boot environment variables:* bootscript: found on <code>boot.scrMVM</code>* Linux kernel: <code>uImage</code>* Device tree blobin the following location: <code>imx6ul-lynx-som0013-cb002f.dtb</code> (or <code>imx6ul-axelulite-cb003a.dtb</code> or <code>imx6ul-axelulite-cb006c.dtb</code>)
