* Fledge and Fledge GUI were not installed by using <code>apt</code>. They were built on the target instead , even though the Linux distribution is still [[ORCA-TN-001_—_Running_Armbian_Bullseye_(Debian_11)|Debian 11]]. This configuration approach may be more suited for development purposesto address different situations. For instance, think about the case in which you have to develop some new functionalities or test custom north/south plugins. This At large, this set-up allows to develop the plugins code on a PC host running the ''same'' distribution, and to migrate them to the target later on when they are it is already tested and debugged thoroughly.* As the target platform features an HDMI port, Fledge GUI can be displayed locally, too. This solution can be convenient for building products that require a local display without having to implement a new graphics application. Interestingly, this HDMI port is provided by a LVDS/HDMI bridge that, in turn, is connected to the LVDS native port of the i.MX8M Plus SoC. The display used for this test is [http://www.magedok.com/product02.html?id=157 Magedok T080A 8-inch touchscreen monitor].

TBDTo visualize the GUI on the local display, we run a web browser configured to operate in kiosk mode.===Installing Weston===First of all, we install [https://wayland.freedesktop.org/ Weston], the compositor required by the browser. <pre class="workstation-terminal"> armbian@sbcorca-00a5:~$ sudo apt updateHit:1 http://deb.debian.org/debian bullseye InRelease...armbian@sbcorca-00a5:~$ sudo apt-get install weston...</pre> Create the file <code>/lib/systemd/system/weston.service</code> with the following contents: ‎<syntaxhighlight>[Unit]Description=Weston wayland compositorAfter=systemd-logind.service # D-Bus is necessary for contacting logind.

To install it, please follow these steps. <pre class="workstation-terminal">armbian@sbcorca-00a5:~$ sudo apt-get install chromiumReading package lists...

To make the change effective, issue the following commands:<pre class="workstation-terminal">armbian@sbcorca-00a5:~$ sudo systemctl daemon-reloadarmbian@sbcorca-00a5:~$ sudo systemctl restart browser</pre>The home page of Fledge GUI will be displayed: [[File:ORCA-TN-003-5.png|center|thumb|600x600px]]
