PetaLinux v2019.1 on Ubuntu 18.04 LTS

Detlev Zundel — Tue, 09 Jul 2019 08:05:51 GMT

Although Xilinx PetaLinux officially supports the Ubuntu 18.04 LTS GNU/Linux distribution, there is a small glitch in the installation procedure. Following UG1144 the installation aborts like this:

dzu@zarniwoop:~/Downloads$ bash petalinux-v2019.1-final-installer.run
INFO: Checking installation environment requirements...
awk: read error (Bad address)

Please refer to the PetaLinux Tools Installation Guide.

Check the troubleshooting guide at the end of that manual, and if you are
unable to resolve the issue please contact customer support with file:
   /home/dzu/Downloads/petalinux_installation_log

petalinux-v2019.1-final-installer.run: line 140: /tmp/tmp.rlFbcgKOQZ/petalinux-env-check: No such file or directory
ERROR: Failed to extract Petalinux installer...
dzu@zarniwoop:~/Downloads$

The fix is rather straightforward and easy, but I'll include the explanation for a better understanding.

Vivado 2018.3 and DocNav on Debian 10 (Buster)

Late last year the ageing effects of my old GNU/Linux desktop system became so severe that ignoring them would soon not be an option anymore. One of the hard disks developed problems a while ago and although I was able to fix it so that finally the extended SMART test passed again without errors, it still continued to report errors in the form of "unreadable (pending) sectors". The on-board USB controller also complains about one of the internal USB ports for a long time and one DDR3 ram module had to be replaced as diagnosed by the wonderful Memtest86.

On top of all this, the Club 3D Radeon X1300PRO dual DVI graphics card started to occasionally hang the whole system a few seconds after waking up from suspend. Or at least that is what I suspect as the system never recorded error messages in the log files. The display however did visibly degrade and I think I saw some drm error message flash by at some point.

Be that as it will, I was glad that I got the chance to replace the system in time and gradually move stuff off a functioning system instead of attaching disassembled hard disks to a new system. The AMD Ryzen 5 2400G system from ARLT Computer, available without Windows, looked like very good value for money. Together with an HDMI to DVI adapter it should also easily power my two DVI monitor setup and so it did not take long until one of them stood beside my desk for installation. As the Ryzen CPU was introduced early in 2018 and the Linux 4.9 kernel at the core of Debian Stretch was released end of 2016, it was clear that I needed to go for the yet unreleased Debian Buster based on Linux 4.19.

All in all things went smoothly until I turned to the Xilinx tool chain that already gave me minor problems described in my previous post Fixing DocNav 2017.04 on Debian Stretch.

Fixing DocNav 2017.04 on Debian Stretch

Having installed Vivado 2017.04 on one of my GNU/Linux machines that run Debian 9.3 (Stretch), I realized that DocNav fails to start:

dzu@deepthought:~$ . /opt/Xilinx/Vivado/2017.4/settings64.sh
dzu@deepthought:~$ docnav
docnav: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory
