FOSDEM 2022 schedule with embedded Linux, IoT, automotive… sessions

While typically taking place in Brussels, Belgium, FOSDEM 2022 will take place online just like FOSDEM 2021 due to COVID-19 restrictions. The good news is that it means anybody can attend it live from anywhere in the world, and makes it more like “FOSDIM”, replacing European with International, in “Free and Open Source Developers’ European Meeting”. FOSDEM 2022 will take place on February 5-6 with 637 speakers, 718 events, and 103 tracks. I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Computer Aided Modeling and Design”, “FOSS on Mobile Devices”, “Libre-Open VLSI and FPGA”, and others. Saturday, February 5, 2022 12:30 – 13:00 – Five mysteries in Embedded Linux by Josef Holzmayr Once you start out in embedded Linux, there is a lot to do. Some things are obvious, some less so. First and foremost, […]

Building a NanoPi M4V2 based All-in-One Linux PC running Armbian (Ubuntu/Debian)

At the end of my review of “RPI All-in-One” PC with Raspberry Pi 4, I noted the system also appeared to be compatible with NanoPi M4V2 single board computer. I’ve now tried it out, and assembling the board inside the 10.1-inch display is even easier than I initially thought. That means I now have a NanoPi M4V2 All-in-One PC running Ubuntu Hirsute or Debian Buster with XFCE desktop environment from Armbian, and most features work including the display and wireless connectivity, but I still have an issue with the touchscreen function. Here are the steps I followed initially: Download Armbian Buster XFCE image from Armbian and flash it to a microSD card with tools like USBimager. Insert the microSD card in the board Install the USB Type-C and HDMI-A adapters in the display. Insert the USB Type-C and HDMI port of the NanoPi M4V2 SBC into the adapters Install the […]

MOREFINE M6 – An ultra-thin Jasper Lake mini PC (Crowdfunding)

We’ve seen a fair amount of Jasper Lake mini PCs, and even reviewed one with Beelink U59. MOREFINE M6 stands out due to its size and thickness, being about the size of two smartphones stacked together. The features are also promising with an Intel Celeron N5105 quad-core processor coupled with up to 16 GB RAM, up to 1TB M.2 NVMe SSD, as well as dual 4K video output through HDMI and USB-C ports, a 2.5GbE ports WiFi 6 & Bluetooth 5.2 connectivity, and three USB 3.1 ports. MOREFINE M6 specifications: SoC – Intel Celeron N5105 quad-core Jasper Lake processor @ 2.0GHz / 2.9GHz (Turbo) with Intel UHD graphics 605; 10W TDP System Memory – 8GB or 16GB LPDDR4 Storage – 512GB or 1TB M.2 NVMe 2280 SSD, or 256GB M.2 SATA SSD Video Output 1x HDMI 2.0 port up to 4Kp60 1x DisplayPort Alt Mode via USB-C port up to […]

Radxa E25 carrier board, 2.5GbE switch, and WiFi 6 router

Radxa E25 2.5GbE switch-Xiaomi AX6000 WiFi 6 router

I’ve just received an early sample of Radxa E25 dual 2.5 GbE carrier board for Radxa CM3 Plus (RK3568) system-on-module, a 2.5GbE TP-Link switch, and Xiaomi AX6000 WiFi 6 + 2.5GbE router. Here’s the back story before looking into the devices. I’ll soon have to review UP Xtreme i11 mini PC with a 2.5GbE port, and after writing about the upcoming ROCK5 Model B SBC with both 2.5GbE and WiFI 6/6E, I realized I should really get some hardware to test 2.5GHz and WiFi 6. So I started to ask what could be the best options for a $200 budget. While thinking about it, I remember Radxa was working on the Radxa E23 board with 2.5GbE, and adding a WiFi 6 USB dongle might be an option. But they told me Radxa E25 would be a better option with two 2.5GbE ports and support for WiFi 6, although that one […]

10.1-inch RPI All-in-One PC review with Raspberry Pi 4

A couple of months ago I received “RPI All-in-One”, a 10.1-inch touchscreen display for Raspberry Pi boards, listed the specifications, checked out the package content, installed a Raspberry Pi 4 inside the display before booting my new all-in-one (AiO) PC successfully. I’ve now had time to spend more time with the PC/display and see how it performs under various conditions. I also tested HDMI and USB-C input features with a laptop and mini PC. Fan or fanless operation? After updating Raspberry Pi OS, I ran sbc-bench.sh script together with rpi-monitor to see how the Raspberry Pi 4 with 1GB RAM would perform under load with the (noisy) fan enabled.

No throttling was detected, and the temperature never exceeded 56°C in a room with an ambient temperature of 26°C. I then disconnect the fan, but it turns out the fan can also be easily disabled in the OSD menu […]

PineNote Developer Edition mainline Linux e-Reader is now available for $399

Pine64 community has been on a tear in 2022, with the launch of the PineNote Developer Edition Linux e-reader following the availability of the PinePhone keyboard case and PinePhone Pro Explorer Edition Linux smartphone in the last 2-3 weeks. So far a limited number of PineNote prototypes had been sent to developers, but it’s now possible to order the PineNote Developer Edition for $399 directly on the Pine64 store. As its name implies, the e-Reader is not ready for end-users, but recent progress with mainline Linux makes it suitable for developers and enthusiasts who want to play around with the device knowing much more work is needed to make it a usable device. The specifications remain the same as in the initial PineNote announcement: SoC – Rockchip RK3566 quad-core A55 processor @ 1.8 GHz with Arm Mali-G52 EE GPU, 0.8 TOPS NPU (AI accelerator) System Memory – 4GB of LPDDR4 […]

Intel launches NUC 11 Essential mini PC, Kits, and SBC with Jasper Lake SoC

Details about the Intel NUC 11 Essential “Atlas Canyon” mini PCs with Jasper Lake processor were leaked in May 2021, but Intel has now made it official with the “launch” of five NUC 11 Essential SKUs with one Windows 11 mini PC with 4GB RAM and 64GB storage, three kits (bare mini PC), and one bare board all listed on Ark Intel. I put “launch” between quotes because it’s only “launched” as stated on Ark Intel, but it does not look like it’s available for sale just yet, but now at least we get confirmation about the specs from the leak that was fairly accurate, except Intel did not launch 10W Jasper Lake J-Series processors, and both 6W and 10W Jasper Lake processors are part of the N-Series. Intel NUC 11 Essential specifications: SoC/memory/storage NUC11ATKC2 Mini PC SoC – Intel Celeron N4505 dual-core processor clocked at 2.0 GHz / 2.9 […]
