Additionally, a U-Boot script file, "tsinit.scr", must be created and placed in the root folder of this partition. In order to do this, a script must be created and converted to the U-Boot .scr format. This process requires a set of U-Boot specific tools. These tools are available on most every Linux distribution, the instructions below are for Debian, either on a host PC or on the device itself. See the package installation documentation for other respective distributions.

Install U-Boot tools in Debian 

apt-get update && apt-get install u-boot-tools -y

Create the file "tsinit.source" in the root of the USB drive with the Linux filesystem: 

# Prepare with:
# mkimage -A arm -T script -C none -n 'imx6ul usb' -d tsinit.source tsinit.scr

# DO NOT MANUALLY EDIT THE .scr FILE

if load usb 0:1 ${loadaddr} /boot/ts${model}-fpga.vme;
        then fpga load 0 ${loadaddr} ${filesize};
fi;

if load usb 0:1 ${fdtaddr} /boot/imx6ul-ts${model}-${baseboardid}.dtb;
        then echo "${baseboardid} detected;"
else echo "Booting default device tree";
        load usb 0:1 ${fdtaddr} /boot/imx6ul-ts${model}.dtb;
fi;

load usb 0:1 ${loadaddr} /boot/zImage;
setenv bootargs root=/dev/sda1 rootwait rw ${cmdline_append} bbid=0x${baseboardid} bbrev=0x${baseboardrev};
run silowaitcharge;
bootz ${loadaddr} - ${fdtaddr};
fi;

Then in the same directory generate the tsinit.scr file: 

mkimage -A arm -T script -C none -n 'imx6ul usb' -d tsinit.source tsinit.scr
