Part 8 - Enable Petalinux webserver & create basic website to serve

This tutorial details the steps required to enable the PetaLinux webserver and create an application to install the files required to form a static & dynamic website.

Setup Xilinx design environment for the 2021.2 toolset.

steve@Desktop:~$ xilinx
Xilinx tools available tools at /opt/Xilinx :-
1) 2021.2 - Vivado - SDK - Vitis - PetaLinux
0) Exit
Please select tools required or exit : 1

Tools are as follows :-
vivado @ /opt/Xilinx/Vivado/2021.2/bin/vivado
vitis @ /opt/Xilinx/Vitis/2021.2/bin/vitis
petalinux-build @ /opt/Xilinx/PetaLinux/2021.2/tool/tools/common/petalinux/bin/petalinux-build

Change the present working directory to be the project directory.

steve@Desktop:~$ cd ~/projects/zedboard_linux/os/petalinux

Launch the PetaLinux configuration tool.

steve@Desktop:~/projects/zedboard_linux/os/petalinux$ petalinux-config -c rootfs

Navigate the menu selecting Filesystem Packages » base » busybox, enable busybox-httpd and then save the configuration and exit the tool. Missing Image!

Create a new auto-enabled installer application.

steve@Desktop:~/projects/zedboard_linux/os/petalinux$ petalinux-create --type apps --template install --name website --enable

Examine the file structure of the newly created installer application.

do_install() {

}

The website will consist of an index page that displays an image of the Zedboard hardware.

Download the ZedBoard image file from Digilent into ~/Downloads. Rename & move this file into the website application area.

steve@Desktop:~/projects/zedboard_linux$ mv ~/Downloads/zedboard-2.png os/petalinux/project-spec/meta-user/recipes-apps/website/files/zedboard.png

Create a simple HTML index page and save this in the website application area.

Edit the BitBake recipe to remove the webserver entries that would allow installation of this application into /usr/bin. Add the entries for index.html & zedboard.jpg to allow installation of these into /srv/www.

Remove the now unused webserver application.

steve@Desktop:~/projects/zedboard_linux$ rm os/petalinux/project-spec/meta-user/recipes-apps/website/files/website

Rebuild the project to include the updated files.

steve@Desktop:~/projects/zedboard_linux$ cd os/petalinux
steve@Desktop:~/projects/zedboard_linux/os/petalinux$ petalinux-build

Package up the project ready for deployment.

steve@Desktop:~/projects/zedboard_linux/os/petalinux$ petalinux-package --prebuilt --force

If not already, connect up the hardware as follows :-

Xubuntu PC USB ⇄ Zedboard USB JTAG/Debug
Xubuntu PC USB ⇄ Zedboard USB UART
Zedboard Ethernet ⇄ Router
Xubuntu PC Ethenet ⇄ Router
Router ⇄ Internet

Set the boot mode jumpers on the Zedboard for JTAG. Missing Image!

Power on the Zedboard.

If not already running, open up a new terminal and launch the MiniCom terminal emulator.

steve@Desktop:~$ minized

Welcome to minicom 2.7.1

OPTIONS: I18n
Compiled on Dec 23 2019, 02:06:26.
Port /dev/ttyACM0, 06:34:25

Press CTRL-A Z for help on special keys

Power cycle the Zedboard and deploy the project via JTAG.

steve@Desktop:~/projects/zedboard_linux/os/petalinux$ petalinux-boot --jtag --prebuilt 3

Access the webserver running on the Zedboard using a browser pointing at the Zedboard's IP address (192.168.2.87). All being well the following static webpage should be displayed. Missing Image!

Add and commit the new & updated files to the repository. Push the updated files but do not tag this release as it is a stepping stone.

steve@Desktop:~/projects/zedboard_linux/os/petalinux$ git add project-spec/meta-user/recipes-apps/website
steve@Desktop:~/projects/zedboard_linux/os/petalinux$ git commit -a -m "Enabled webserver application and created website installer application (static)."
steve@Desktop:~/projects/zedboard_linux/os/petalinux$ git push

The dynamic (server side) website will contain the same elements as the static website plus some extra system information that will be provided live when the page loads or is reloaded.

Create a shell script like the one shown below that outputs what the previous index.html provided directly along with the additional information. This shell script will be called index.cgi and ultimately reside in /srv/www/cgi-bin.

steve@Desktop:~/projects/zedboard_linux/os/petalinux$ cd ../..

Modify the BitBake recipe to reflect the addition of the cgi-bin directory and index.cgi script, ensure the script entry sets the execution bit of the file. The webserver looks for the index file in /srv/www before looking in /srv/www/cgi-bin so the original index.html is temporarily renamed to take this out of the equation.

Reload the page to refresh all the information displayed, most of which is static except for elements such as time, uptime, load & memory. The index.cgi page can be accessed directly via [Zedboard IP]/cgi-bin/index.cgi and the original index.html via [Zedboard IP]/index_original.html.

Add and commit the new & updated files to the repository. Push the updated files but do not tag this release as it is a stepping stone.

steve@Desktop:~/projects/zedboard_linux/os/petalinux$ git push

The dynamic (client side) website will contain the same elements as the previous dynamic (server side) website along with the ability to refresh the uptime element without reloading the whole page.

Create a shell script that returns the uptime in seconds.

steve@Desktop:~/projects/zedboard_linux/os/petalinux$ cd ../..

Create a Javascript file that contains the functions required to send & receive data to & from the webserver. Also add a function to enable & disable a timer.

steve@Desktop:~/projects/zedboard_linux$ subl os/petalinux/project-spec/meta-user/recipes-apps/website/files/uptime.js

var timer_req;

    txtObj = document.getElementById("uptime_text");
    if (txtObj !== null) {
      txtObj.innerHTML = uptime_req.responseText;
    }
  }

Modify the index.cgi webpage as follows :-

Add an include entry for the new uptime.js Javascript file (line 25).
Modify the uptime entry (line 36) to wrap the data inside an element with the unique ID of uptime_text as used by the GotUpTime Javascript function.
Add a button (line 37) to call the GetUpTime Javascript function such that the uptime can be refreshed when the button is pressed without reloading the whole page.
Add a dropdown (lines 38-42) to call the SetTimeout Javascript function such that a timer can be used to automatically refresh the uptime without reloading the whole page.

The source files relating to this tutorial for the OS can be obtained from Bitbucket. The OS repository contains both PetaLinux and a local copy of the exported hardware (firmware).

The instructions below assume that Part 1 - Installation of tools, setup of environment and creation of project area has been completed in full and that the environment has been setup as per 1. Setup environment. The root project area ~/projects should be present and contain the common project. The zedboard_linux projects should NOT be present. Adjust the commands below to suit if the above differs.

Obtain OS source, build & deploy on Zedboard.

steve@Desktop:~$ cd ~/projects
steve@Desktop:~/projects$ git clone -b v4.0 https://bitbucket.org/spacewire_firmware/zedboard_linux
steve@Desktop:~/projects$ cd zedboard_linux/os/petalinux

Do something with the OS (if required) then perform the following steps :-

Build PetaLinux
Package PetaLinux
Setup Zedboard hardware
Launch MiniCom terminal emulator
Run PetaLinux on Zedboard via JTAG
Check everything is working as expected
