Embedded Open Source Summit 2024 schedule – Embedded Linux, Zephyr OS, and Real-time Linux

Embedded Open Source Summit 2024

The Embedded Open Source Summit 2024 (EOSS 2024) will take place on April 16-18 and the Linux Foundation has already announced the schedule with conference sessions, lightning talks, and birds of a feather (BoF) sessions covering embedded Linux, Zephyr OS, and real-time (RT) Linux. While I won’t be attending in person, I still find it interesting to check out the schedule as we may learn more about the current status of embedded Linux. So I’ve created my own little virtual schedule out of the available talks. Tuesday, April 16 – Day 1, Embedded Open Source Summit 2024 9:05 – 9:45 – No, It’s (Still) Never Too Late to Upstream Your Legacy Linux-Based Platforms by Neil Armstrong, Linaro Nearly 7 years ago, Neil already spoke about this subject in Berlin, and it’s still very true. Do you maintain or used to maintain a Linux-based board or SoC off-tree? Then there are […]

FOSDEM 2024 schedule – Open-source embedded, mobile, IoT, robotics, RISC-V, etc..

FOSDEM 2024

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where thousands of developers meet in Brussels on the first week-end of February to discuss open-source software & hardware projects. FOSDEM 2024 will take place on February 3-4 with 880 speakers, 818 events, and 66 tracks. Although I won’t attend, I’ve created a virtual schedule like every year with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms including “FOSS Mobile Devices”, “ Energy: Reimagining this Ecosystem through Open Source”, “RISC-V”, and others. FOSDEM Day 1 – Saturday, February 3, 2024 10:30 – 10:55 – Screen Sharing on Raspberry Pi 5 Using VNC in Weston and Wayland with the Yocto Project and OpenEmbedded by Leon Anavi In 2023, embedded Linux developers received eagerly awaited news: […]

Giveaway Week 2023 – Elecrow ESP32 Terminal with a 3.5-inch touchscreen display and OV2640 camera

Elecrow ESP32 Terminal giveaway

If I remember correctly, Elecrow sent me an end-of-year gift with a notebook (paper style), a pen, and a 3.5-inch ESP32 terminal. I had completely forgotten about it, and while wondering what I would give for Giveaway Week 2023, and looking around in drawers and on shelves, I found an “ESP32 Terminal” package, and I was like “What the F is that and where is it coming from?”. Long story short, the 6th prize of this year’s giveaway week is Elecrow’s ESP32 Terminal with a 3.5-inch touchscreen display that also comes with a front-facing OV2640 camera and six Crowtail connectors for expansion plus a LiPo battery connector. Elecrow ESP32 terminal specifications: Wireless module – ESP32-S3 2.4 GHz Wi-Fi and Bluetooth 5 (LE) module with 16MB flash and 8MB PSRAM Storage – MicroSD card slot Display – 3.5-inch TFT LCD display with 480×320 resolution (ILI9488 driver), capacitive touchscreen Camera – 2MP […]

Alibaba T-Head TH1520 user manuals released

Alibaba T-Head TH1520 user manuals

Further Alibaba T-Head TH1520 quad-core RISC-V processor documentation has been released with nine user manuals covering video and audio processing, peripheral interfaces, memory interfaces, system registers, and the built-in NPU for video acceleration. We first noted the TH1520 RISC-V SoC in the expensive web3-focused ROMA laptop in October 2022, but since then there have been some very interesting developments with the release of Sipeed’s Lichee Pi 4A SBC and various other platforms based on the LM4A system-on-module plus the BeagleBoard.org’s BeagleV Ahead. Both boards also have preliminary support in mainline Linux with the Lichee Pi 4A making it to Linux 6.5, and the BeagleV Ahead was added to the just-released Linux 6.6 kernel. However I had not noticed documentation for the processor was not released publicly until now as both Sipeed and Beagleboard.org have now made available nine user manuals in English, and the Sipeed link has the Chinese versions […]

Qualcomm Snapdragon X Elite – A 4.3 GHz 12-core Arm AI processor for next gen PCs and laptops

Qualcomm Snapdragon X Elite highlights

Qualcomm has now provided Arm chips for mobile PCs (aka laptops) for several years, but apart from a 20-hour battery life, the performance and price of Snapdragon laptops have often been disappointing. The Snapdragon X Elite aims to change that at least on the performance front. The new Qualcomm 12-core 64-bit Arm processor is clocked at up to 3.8 GHz boosting to up to 4.3 GHz, and is said to deliver up to twice the CPU performance against the competition (Intel/AMD/Apple) or provides the same level of performance at a third of the power consumption. The SoC will also be able to run on-device generative AI with over 13B parameters thanks to 75 TOPS of AI performance and support the latest wireless connectivity technologies such as 5G and WiFi 7 through external chips from the company. Qualcomm Snapdragon X Elite specifications: CPU – 12-core 64-bit Armv8 Oryon processor clocked at […]

Arm: “Panfrost is now the GPU driver for the Linux community”

Arm Panfrost Linux

Arm is now saying that “in effect, Panfrost is now the GPU driver for the Linux community” after having extended and expanded the collaboration with Collabora for the development of the open-source Panfrost driver for Arm Mali GPUs, following their first official collaboration in the fall of 2020. Arm goes even as far as to claim that “through the Arm and Collabora partnership, device manufacturers can confidently choose SoCs containing a Mali GPU regardless of the software operating system (OS) and graphics middleware… delivering a high-quality open-source Linux implementation which can be used in their products”. Collabora confirmed the new partnership saying Arm will be instrumental in getting Vulkan support in Panfrost alongside the existing OpenGL and OpenGL ES implementations. Going forward that means SBC vendors will have no excuse for not getting 3D graphics acceleration working on Linux with Panfrost when using an Arm SoC with a recent Mali […]
