Ubuntu 16 arm32 on PetaLinux with custom hdf

Basically I needed to load Ubuntu 16.04 on a SBC ARMv7. I listed down the pages I used for references.

Links for custom hdf for fpgma

Links for kernel configuration

Links that I used to troubleshoot:

JunOS EX2200 Firmware Upgrade

Since I have a EX2200, I thought I should at least upgrade its firmware. But JunOS firmware upgrade didn’t go as user-friendly as I thought. Anyways, this is what I did to upgrade from 11.1R3.5 to 12.3R12.4

Key Notes:

  • Don’t use the Web Interface to upgrade. It is slow and does not seem to work.
  • Upload the firmware to a web server that allows direct linking.
  • The reboot process takes more than 15 minutes. Do not be alarmed if the switch seems to be dead during the process.

Steps via Cli

PetaLinux 2019.1 Installation Steps on Ubuntu 18.04 64-bit

Xilinx’s PetaLinux installation guide doesn’t give a simple one liner to install all of its dependencies. So I wrote down what I did.

Tried and tested on Ubuntu 18.04 LTS 64-bit (under non-root user)

Key Notes:

  1. Installation takes about 15 minutes on a ssd due to the extraction and copying of data
  2. Takes up about 5 GB of space.
  3. Remember to use a non root user or else the installer will not continue and you have to restart from scratch

Dependencies:

sudo apt-get install gcc-multilib build-essential libsdl1.2-dev libglib2.0-dev python2.7 tofrodos gawk xvfb gcc-4.8 g++-4.8 git make net-tools libncurses5-dev tftpd zlib1g-dev libssl-dev flex bison libselinux1 gpg wget diffstat chrpath socat xterm autoconf libtool tar unzip texinfo zlib1g:i386 libsdl1.2-dev libglib2.0-dev

Installation:

mkdir -p /opt/pkg/petalinux/2019.1
sudo chmod 755 -R /opt
sudo chown admin:admin -R /opt
./petalinux-v2019.1-final-installer.run /opt/pkg/petalinux/2019.1
export PATH="/opt/pkg/petalinux/2019.1/tools/common/petalinux/bin/:$PATH"
source /opt/pkg/petalinux/2019.1/settings.sh
