This post just lists the commands used to create, build and run a PetaLinux build. It may be useful if you need to refer to a flow that worked. The commands were run using PetaLinux 2017.4.
Before you Start
Instructions to set up download and install PetaLinux Tools are here.
Commands
Commands to rebuild
In one terminal:
# Set up ENV
source /home/org/zach/tools/opt/pkg/petalinux/settings.sh
source /home/org/zach/set_petalinux_env.sh
which make
which petalinux-create
cd /home/org/zach/proj/proj2/
export DISPLAY=dummy; /opt/Xilinx/SDK/2017.4/bin/xsct robust-kernel.txt
# Run again to ensure we can reset the target
export DISPLAY=dummy; /opt/Xilinx/SDK/2017.4/bin/xsct robust-kernel.txt
In another terminal:
minicom -o -w -C today.log
Rebuild
petalinux-build
You should see:

Commands to Create your Own Build
To create your own build
cd /home/org/zach/proj
# Check your environment
source /home/org/zach/tools/opt/pkg/petalinux/settings.sh
source /home/org/zach/set_petalinux_env.sh
which make
which petalinux-create
# Create a project
petalinux-create --type project --template zynqMP --name proj4
cd proj4
# Get the HDF, stored in the directory above
petalinux-config --get-hw-description=../
# Select S and E
# done with petalinux-config --get-hw-description=../ *************
# Build it
petalinux-build
# This vvvv is not needed since we’re going to overwrite it, but its useful to see what PetaLinux is doing
petalinux-boot --jtag --kernel --tcl kernel.txt --hw_server-url 192.168.13.111:3121

#VI command to change the dir :%s/proj/proj4/gc
# Test the build
# start a minicom in another terminal
minicom -o -w -C 20180309.log
# Program the build over JTAG
export DISPLAY=dummy; /opt/Xilinx/SDK/2017.4/bin/xsct robust-kernel.txt
# Save boot to proj3_no_change_boot.txt
# Now update kernel config and add dtsi

# if you try and run this, when export DISPLAY=dummy has been set it will fail. You need to open a new window and re-run the set up
petalinux-config -c kernel
#Has an errror in petalinux-config-error1.txt, when I tried to run: export DISPLAY=dummy; /opt/Xilinx/SDK/2017.4/bin/xsct robust-kernel.txt in the same window so open a new window and run: /opt/Xilinx/SDK/2017.4/bin/xsct robust-kernel.txt
