Linux 5.1 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has just announced the release of Linux 5.1: So it’s a bit later in the day than I usually do this, just because I was waffling about the release. Partly because I got some small pull requests today, but mostly just because I wasn’t looking forward to the timing of this upcoming 5.2 merge window. But the last-minute pull requests really weren’t big enough to justify delaying things over, and hopefully the merge window timing won’t be all that painful either. I just happen to have the college graduation of my oldest happen right smack dab in the middle of the upcoming merge window, so I might be effectively offline for a few days there. If worst comes to worst, I’ll extend it to make it all work, but I don’t think it will be needed. Anyway, on to 5.1 itself. The past week has been pretty calm, […]

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 […]

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 […]

Pioneer Edition FreedomBox Home Server Launched with Olimex A20-OLinuXino-LIME2 Board

Olimex works on open source hardware boards, while the FreedomBox Foundation has been developing FreedomBox, a free and open source private server system, since 2010 with the goal of empowering regular people to host their own internet services, like a VPN, a personal website, file sharing, encrypted messengers, a VoIP server, a metasearch engine, and more. When you mix open source hardware, open source software, and a bit of Internet freedom it gives birth to a product called “Pioneer Edition FreedomBox Home Server” based on Olimex A20-OLinuXino-LIME2 board and running FreedomBox software. Pioneer Edition FreedomBox Home Server specifications: SoC – Allwinner A20 dual-core ARM Cortex-A7 CPU @ 1.0 GHz with dual-core Mali 400 GPU System Memory – 1GB DDR3 Storage – microSD slot fitted with 32GB class 10 card loaded with FreedomBox, SATA data and power connectors, 2KB EEPROM for MAC address and custom data Connectivity – Gigabit Ethernet Video […]

MIPS Based TritonAI 64 AI IP Platform to Enable Inferencing & Training at the Edge

After announcing their first MIPS Open release a few weeks ago, Wave Computing is back in the news with the announcement of TritonAI 64, an artificial intelligence IP platform combining MIPS 64-bit + SIMD open instruction set architecture with the company’s WaveTensor subsystem for the execution of convolutional neural network (CNN) algorithms, and WaveFlow flexible, scalable fabric for more complex AI algorithms. TritonAI 64 can scale up to 8 TOPS/Watt, over 10 TOPS/mm2 using a standard 7nm process node, and eventually would allow both inference and training at the edge. The platform supports 1 to 6 cores with MIPS64r6 ISA boasting the following features: 128-bit SIMD/FPU 8/16/32/int, 32/64 FP datatype support Virtualization extensions Superscalar 9-stage pipeline w/SMT Caches (32KB-64KB), DSPRAM (0-64KB) Advanced branch predict and MMU Integrated L2 cache (0-8MB, opt ECC) Power management (F/V gating, per CPU) Interrupt control with virtualization 256b native AXI4 or ACE interface Here’s the […]
