    Zynq guide #1 - getting started


    This is the first article of a series about the Zynq-7000 SoC from Xilinx. Though not a particularly new SoC, it is still quite unique as it features an FPGA in conjunction with a Cortex-A9 CPU. This opens a bunch of interesting application scenarios since the FPGA can act as a customisable co-processor or hardware accelerator. In this article, I will guide you through the very basic board bring-up to get a first sign of life from this hardware with Genode. Continue...

    Mobile networking in Sculpt


    Last year, ssumpf added basic LTE modem support to Genode. Since many Sculpt-compatible laptops come with integrated LTE modems already or can be easily upgraded, I started a little side project to equip Sculpt with easy-to-deploy mobile networking support. In this article, I summarise how to reap the fruits of this project. As a side effect, it showcases the varied possibilities of component compositions. Continue...

    Dynamically changing keyboard remapping rules


    When setting up my Sculpt-based work environment, my intent was to run an unmodified Linux installation as VM in Sculpt. Being strongly accustomed to i3wm, I quickly noticed the lack of the Windows key that is used for controlling the i3 window manager but which is intercepted by Sculpt for the same job. A bit reluctant to change my habits and retrain new key combos, I needed a better solution. With advice from Norman, I came to a pretty neat solution that I would like to share with you. Continue...

    Native screenshot component


    Martin had recently expressed to me that a native screenshot component using the Capture session would be really helpful. Moreover, when writing the VNC server article, I also encountered the need to make a screenshot myself. As I already got in touch with the Capture session, I briefly switched contexts to bring the screenshot component into being right away. Continue...

    Remote desktop solution for Sculpt via VNC


    Thanks to alex-ab, we already have a native VNC client available in Sculpt to connect to VMs remotely. How nice would it be to also bring a VNC server to Sculpt and thereby enable remote desktop scenarios? In this article, I want to share my experiences made when developing a VNC server application with Goa and ultimately present a ready-to-use package for Sculpt. Continue...

    Do you 🖤 your 💻?


    Once in a while, I come across a website that uses unicode emoji for illustration. Github is one of these that uses such symbols in the sidebar of the notification view. However, if you do not have a font installed that contains the corresponding glyphs, you will only see those beautiful inexpressive boxes ⌷ (or even whitespace). This is the case for the falkon browser packaged for Sculpt. Yet, it is pretty easy to augment it with emoji support. Continue...

    Troublesome guest additions


    On my journey towards transitioning to Sculpt as a day-to-day OS, I already desribed how to access an existing Linux installation in my previous article. Since I recently struggled with installing the VirtualBox Guest Additions, I want to share my findings with a short follow up article. Continue...

    Starting an existing Linux installation from Sculpt


    In the last years, I've had an on-and-off relationship with Genode mostly because other commitments kept me from spending time with the framework. Although I was keen on using Sculpt as a day-to-day OS, I didn't manage to make a smooth transition. Initially, my idea was to use my existing Linux system and install Sculpt in parallel. Ideally, I would be able to start my existing Linux system in Virtualbox on Sculpt. My first efforts were stalled by some EFI boot issues and due to a lack of time this idea slumbered for about two years...until recently. Continue...
