Pinebook Pro Arm Laptop Video Demo

Pine64 first revealed working on Pinebook Pro Arm Linux laptop at FOSDEM 2019 back at the end of January. The first Pinebook laptop had limited hardware resources, and as such was meant for simple tasks, but Pinebook Pro equipped with Rockchip RK3399 processor, 4GB RAM, 64GB to 128GB flash, and a 14″ Full HD display is designed to be used as your main laptop. That means everything needs to work from 3D graphics acceleration, to hardware video decoding, and USB-C video output. Lukasz Erecinski very recently shot a demo of the laptop in action, and everything looks very good, meaning the laptop should be come available soon. You can watch the demo further below, but if you are in a rush here’s what has been tested and works: Ubuntu & Debian with MATE desktop 4K video playback 3D graphics acceleration for games (Quake demo) 3D graphics acceleration in Chromium web […]

Toradex Torizon Industrial Linux Distribution Targets Windows Developers

When we interviewed Toradex right before Embedded World 2019, they told us they would focus on their new software offering called Torizon, an easy-to-use industrial Linux Platform, especially targeting customers are coming from the Windows / WinCE environment or who have only experience with application development and are not embedded Linux specialists. The company has now officially launched Torizon, and provided more details about their industrial open source software solution especially optimized for their NXP i.MX modules. Torizon specifically relies on foundries.io Linux microPlatform which provides full system with a recent stable kernel, a minimal base system built with OpenEmbedded/Yocto, and a runtime to deploy applications and services in Docker containers. The microPlatform is part of TorizonCore (light blue section above) that also includes an OTA client (Aktualizr). TorizonCore is free open-source software, and serves as the base to run software containers. To get started, Torizon provides a Debian container […]

This Open Source Hardware Smartwatch Project is Fully Documented

While there are plenty of smartwatches available, they may not perfectly match your requirements and needs. But did you wake up one day and just decided to build your own? Probably not. But Samson March had his own plans, and as a professional electrical engineer and product designer, he decided to start a smartwatch project during his spare time. What makes it really interesting is that he provided a long list of photos and short videos explaining in details the process, and open-sourced all materials from hardware design files, to firmware source code, and 3D print files for the body and charging dock! The OSHW watch does not have a name (yet) and features the following hardware: Wireless MCU – Dialog Semiconductor DA14683 Arm Cortex-M0 microcontroller up to 96 MHz 128KB RAM, 128KB ROM, 64KB OTP, and with Bluetooth 5.0 connectivity Storage – 128 Mbit SPI flash Display – 1.3″ […]

Facebook Oculus Quest Standalone VR Headset Launched for $399 and up

One year ago, Facebook introduced their very first standalone virtual reality headset with Oculus Go. At $199 the price was fairly attractive, but the headset only supported 3DOF motion tracking. The company announced a new model at F8 2019. Oculus Quest is equipped with a more powerful Snapdragon 835 processor, two 1600 x 1440 displays, and support for 6DOF (degrees of freedom) virtual reality thanks to two handheld motion controllers. Oculus Quest specifications: SoC – Qualcomm Snapdragon 835 octa-core processor with 4x high performance Kryo 280 cores @ 2.20 GHz/ 2.30 GHz (single core operation), 4x low power Kryo 280 cores @ 1.9 GHz, Adreno 540 GPU System Memory – 4GB RAM Storage – 64GB or 128GB flash storage Display – 2x 1600×1440 OLED displays up to 72 Hz Camera – 4x wide-angle tracking cameras for inside-out position tracking Audio – Integrated speakers, 2x 3.5mm audio jacks Battery – Lithium-Ion […]

Rockchip RK1808 Datasheet, TRM, Schematics and Linux SDK Released

Rockchip RK1808 is the first chip from the company fully dedicated to artificial intelligence applications. The Neural Processing Unit (NPU) features an accelerator delivering up to 3.0 TOPS and is coupled with two low power Arm Cortex-A35 cores allowing it to run Linux. We’ve had the specifications for RK1808 for a while, but the company has recently posted hardware and software resources on their open source website. On the hardware side we’ve got: RK1808 Technical Reference Manual (TRM) RK1808 datasheet PDF Schematics for the company’s official RK1808-EVB On the software side we can get the Linux SDK from Github as explained in the Wiki:

git clone https://github.com/rockchip-linux/repo
mkdir linux
cd linux
../repo/repo init --repo-url=https://github.com/rockchip-linux/repo -u https://github.com/rockchip-linux/manifests -b master -m rk1808_linux_release.xml
../repo/repo sync

git clone https://github.com/rockchip-linux/repo

mkdir linux

cd linux

../repo/repo init --repo-url=https://github.com/rockchip-linux/repo -u https://github.com/rockchip-linux/manifests -b master -m rk1808_linux_release.xml

../repo/repo sync

Finally configure the build and start the build process:

sudo apt install liblz4-tool build-essential
source envsetup.sh rockchip_rk1808
./build.sh

sudo apt install liblz4-tool build-essential

source envsetup.sh rockchip_rk1808

./build.sh

After a while, or more accurately close to two hours on a Laptop with Ryzen 7 2700U processor, 8GB RAM, and hard drive, we’ll get U-boot, Linux, buildroot based rootfs, and firmware files and in […]

Giggle Score Says ODROID-N2 Best Value, Raspberry Pi Zero Worst Value

[Update May 7, 2019: Giggle Score has been updated to use 7-zip to benchmark the boards instead of sysbench, and the “best value” rankings are now quite different] People like to compare single board computers, and usually want to have a simple answer as to which is better than the others. But in practice it’s impossible, because the beauty of SBCs is that they are so versatile and can be used in a wide variety of project, and that means in some cases the “best board” may be completely useless to you since it lacks a critical feature and interface for YOUR project be it H.265 video encoding or a MIPI DSI display interface. Still, it’s still always fun to look at benchmark scores and trying to compare SBCs, and for projects that mostly require CPU processing power it may also be useful. Robbie Ferguson has been developing and maintaining […]
