Ampere eMAG 64bit Arm Workstation Enables Native Arm Development

Over the last few years, several companies have come up with 64-bit Arm workstation to allow developers to test Arm code natively which may be important to avoid network delays or test applications requiring video or graphics. Those started to become available in 2018 from the relatively low-end 24-core Cortex-A53 Linaro “Synquacer” Developerbox to the much more powerful (and expensive) GIGABYTE ThunderXStation Workstation powered by up to two 32-core ThunderX2 processors. In the fall of 2019, SolidRun started to ship HoneyComb LX2K 16-core Arm Workstation motherboard with and NXP LX2160A 16-core Cortex-A72 processor that offers significantly more performance than the Linaro Box at a reasonable price ($750). While reading a recent Anandtech post with photos of an engineering sample, I found out Avantek was also offering the Ampere eMAG 64bit Arm Workstation powered by an Ampere eMAG 8180 32-core server processor. Ampere eMAG 64-bit Arm workstation specifications: SoC – Ampere […]

Raspberry Pi 4 vs ODROID-C4 Features Comparison

Yesterday, Hardkernel launched ODROID-C4 Amlogic S905X3 SBC as an update to ODROID-C2 SBC launched in 2016. We’ve seen the board can compete with Raspberry Pi 4 4GB board thanks to benchmarks released by Hardkernel, but since those boards are so versatile, meaning they can be used in a variety of applications, it’s impossible to benchmark all use cases. One way to find out which board might be right for your application without going through benchmarks is to look at a list of features for each, and that’s exactly what we’ve done in this post. Let’s get straight to the Raspberry Pi 4 (4GB RAM) vs ODROID-C4 comparison table. Features/Specs Raspberry Pi 4B (4GB) ODROID-C4 Release date 24th June 2019 23rd April 2020 SoC Broadcom BCM2711 quad-core Cortex-A72 @ 1.5 GHz (overclockable to 2.0+ GHz) with NEON, FPU Amlogic S905X3 quad-core Cortex-A55 processor @ 2.0 GHz with NEON, FPU, Armv8 Crypto […]

Panfrost Gets First 3D Renders on Bifrost GPU (Mali-G31) including Basic Texture Support

Collabora has been working on Panfrost open-source Arm Mali GPU driver for over a year. The drive aims to support both Midgard and Bifrost families. But so far, the company had mostly focused on Midgard (Mali-T6xx/T7xx) GPUs with for example experimental OpenGL ES 3.0 support announced last February. Collabora engineers, such as Alyssa Rosenzweig, have now started to work on Bifrost support, and some good progress has been made since they managed to have Panfrost render the first 3D graphics with basic texture support using a platform with an Arm Mali-G31 GPU. Alyssa notes that while Midgard and Bifrost have a similar command stream requiring a few changes, the Bifrost instruction set is completely different and required building a new compiler from scratch. This leads to changes to the Intermediate Representation (IR), 16-bit data support, a different register allocation mechanism due to adapt to irregular vector architectures, and the latter […]

Ubuntu 20.04 LTS Released – What’s New?

Ubuntu 18.04 “Bionic Beaver” was released nearly exactly two years ago, and that means it’s time for another LTS (Long Term Support) release with Canonical officially releasing Ubuntu 20.04 “Focal Fossa” today. There are a few changes to the graphical user interface, Amazon Icon is now gone, a recent Linux 5.4 kernel is used by default with Wireguard VPN backport, and snap becomes a first citizen in Ubuntu 20.04. This is also the first LTS version of Ubuntu that does not provide 32-bit x86 images. Ubuntu 20.04 ISO files will soon be found on Ubuntu website, and if you already a machine with Ubuntu 18.04 or 19.10, you should be able to upgrade with the following commands:

sudo apt update 
sudo apt dist-upgrade 
sudo apt install update-manager-core
sudo do-release-upgrade

sudo apt update

sudo apt dist-upgrade

sudo apt install update-manager-core

sudo do-release-upgrade

It’s possible the release has not been pushed to your mirror, so you may need to wait for a little while, or use the command to install the development release :

sudo do-release-upgrade -d

1	sudo do-release-upgrade -d

$50 ODROID-C4 Raspberry Pi 4 Competitor Combines Amlogic S905X3 SoC with 4GB RAM

Hardkernel has just launched an update to its ODROID-C2 board, with ODROID-C4 SBC equipped with a 2.0 GHz Amlogic S905X3 quad-core Cortex-A55 processor combined with up to 4GB RAM, four USB 3.0 ports, Gigabit Ethernet, HDMI 2.0 video output, and the usual 40-pin I/O header. That makes it a worthy competitor to Raspberry Pi 4 with 4GB RAM, especially since it supports Ubuntu 20.04, CoreELEC, Android 9, and LineageOS operating systems, and comes with a proper heatsink for cooling for just $50 plus shipping. ODROID-C4 specifications: SoC – Amlogic S905X3 quad-core Cortex-A55 processor @ 2.0GHz with Arm Mali-G31MP2 GPU supporting OpenGL ES 3.2, Vulkan 1.0 and OpenCL 2.0 System Memory – 4GB DDR4 Storage 1x eMMC connector (8/16/32/64GB modules available) 1x Micro SD slot with support for DS/HS mode up to UHS-I SDR104 Video & Output – HDMI 2.0 port up to 4K@60Hz with HDR, CEC, EDID Audio – Digital […]

Qt for MCUs 1.1 Adds Support for more STM32 and NXP i.MX RT Boards, FreeRTOS

The first stable version of Qt for MCUs was released in August 2019 in order to bring Qt graphical toolkit to microcontrollers such as STMicro STM32F7, Renesas RH850, or NXP i.MX RT1050. Qt for MCUs would run bare metal on supported boards, and software engineers would develop graphical interface using QML and C++. Qt for MCUs 1.1 has just been released with the addition of more STM32 and i.MX RT boards, support for FreeRTOS real-time operating system, and more. Qt for MCUs 1.1 highlights: Five new supported boards: NXP i.MX RT 1064 EVK, STM32 H750B-DK, STM32 F469i-disco, STM32 L4R9i-disco, and STM32 L4R9i-eval Asset management Optional PNG compressions for assets to lower storage footprint Option to read data directly from flash memory for lower RAM consumption, or copy to RAM for better performance, at the cost of higher RAM consumption. FreeRTOS support (technology preview) to run background tasks without blocking the […]

Is MIPS Dead? Lawsuit, Bankruptcy, Maintainers Leaving and More…

When in 2018, Blu posted a guest post entitled “Baikal T1 MIPS Processor – The Last of the Mohicans?” I thought maybe it was too pessimistic with regard to the future of MIPS architecture. At the time, MIPS belonged to Imagination Technologies, but soon the company had its own financial problems and had to sell MIPS assets to Wave Computing. The latter eventually announced the launch of MIPS Open Initiative early last year, so there was some hope as interest might pick up to compete against RISC-V and Arm again. But in recent months, MIPS related news has not been so good. First, Wave Computing decided to end MIPS Open Initiative in November 2019, then Paul Burton and Ralf Baechle removed themselves from the Linux kernel MIPS maintainer list in February 2020, as their work with MIPS ended leaving Thomas Bogendoerfer as the only maintainer. But this month, things turned […]

AAEON Compact Fanless Embedded Box PC Features NVIDIA Jetson Xavier-NX or Nano SoM

NVIDIA Jetson Xavier-NX module was officially launched about a week ago, and at the time we noted several carrier boards and mini PCs were launched or announced from companies like D3 Engineering, Diamond Systems, and Connect Tech. We should expect many new Jetson Xavier-NX embedded mini PC announcements over the next few weeks and months, and AAEON has now announced two new similar compact fanless embedded box PCs namely Boxer-8221AI and BOXER-8251AI with the same designed but powered by respectively Jetson Nano and Jetson Xavier-NX modules. Both models should share the same specifications except for the module: SoM Boxer-8221AI – NVIDIA Jetson Nano with quad-core Arm Cortex-A57 processor @ 1.43 GHz, 128-core Maxwell GPU, 4GB LPDDR4, 16GB eMMC flash Boxer-8251AI – NVIDIA Jetson Xavier-NX with 6-core NVIDIA Carmel ARM v8.2 64-bit CPU, a 384-core NVIDIA Volta GPU with 48 Tensor Cores, 2x NVDLA deep learning accelerators (up to 21 TOPS […]
