March 9, 2018

 

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 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

cp ../proj/robust-kernel.txt .

vi robust-kernel.txt

# http://vim.wikia.com/wiki/Search_and_replace

#

#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

 

cp /home/org/zach/proj/proj2/project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi project-spec/meta-user/recipes-bsp/device-tree/

 

# 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
