The one addition is to create the tsinit.ub file in the root of the USB drive. In order to do this, a U-Boot script must be created and then converted to the .ub format. This process requires a set of U-Boot specific tools. These are available on most every linux distribution, the instructions below are for Debian, either run 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.scr in the root of the USB drive with the linux filesystem: 

# Prepare with:
# mkimage -A arm -T script -C none -n 'ts7553v2 usb' -d tsinit.scr tsinit.ub

# DO NOT MANUALLY EDIT THE .UB FILE

load usb 0:1 ${fdtaddr} /boot/imx6ul-ts7553v2${variant}.dtb;

load usb 0:1 ${loadaddr} /boot/zImage;

setenv bootargs root=/dev/sda1 ${cmdline_append};
bootz ${loadaddr} - ${fdtaddr};

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

mkimage -A arm -T script -C none -n 'ts7553v2 usb' -d tsinit.scr tsinit.ub
