BalenaOS may be the First Fully Functional 64-bit OS for Raspberry Pi 4

Raspberry Pi 4 64-bit OS

BalenaOS 64-Bit OS Balena just announced the release of a 64-bit OS for the Raspberry Pi 4, that latest release of the iconic SBC. BalenaOS is designed to run 32-bit and 64-bit Docker containers side-by-side and simultaneously.  It also supports up to 4GB of memory, to accomplish that feat. The balenaOS also supports several other embedded systems and versions of Raspberry Pi How BalenaOS Is Set Up The BalenaOS is opensource, Yocto Linux-based host OS made for containers. The workflow is fast and current and allows for a number of different embedded systems, but especially Raspberry Pi 4 in a 64-bit environment. The Main Advantage With the advances in the Raspberry Pi 4 platform, the faster data throughput, improved graphics handling, and the faster processor speeds, the BalenaOS is taking full advantage of the Raspberry Pi 4.  It adds a wide variety of possibilities to a platform that was waiting for this improvement.  Embedded System Function The OS has developed …

How to Sandbox an arm64 GCC on aarch64 Hardware with armv7 Userspace

Arm64 GCC Armv7 Userspace

CNXSoft: Guest post by Blu about setting up arm64 toolchain on 64-bit Arm hardware running a 32-bit Arm (Armv7) rootfs. Life is short and industry progress is never fast enough in areas we care about. That’s an observation most of us are familiar with. One would think that by now most aarch64 desktops would be running arm64 environments, with multi-arch support when needed. Alas, as of late 2019, chromeOS on aarch64 is still shipping an aarch64 kernel and an armhf userspace. And despite the fine job by the good folks at chromebrew, an aarch64 chromeOS machine in dev mode ‒ an otherwise excellent road-warrior ride, is stuck with 32-bit armhf. Is that a problem, some may ask? Yes, it is ‒ aarch64 is the objectively better arm ISA outside of MCUs, from gen-purpose code to all kinds of ISA extensions, SIMD in particular. That shows in contemporary compiler support and in the difference in quality of codegen. Particularly with the …

NetBSD ARM64 Images Now Available with SMP for Raspberry Pi 3, Some NanoPi Boards, and Pine64 Boards

ROCK64 NetBSD ARM64

NetBSD on Arm started in 2014 with the release of version 7.0, and last year device tree support was implemented and tested on some Allwinner H3 boards. But apparently, so far NetBSD only supported 32-bit Arm, with initial support for 64-bit Arm (ARM64) committed last April, but good progress has been made, and NetBSD ARM64 bootable firmware images are now available with SMP (multi-core) support. Eight different NetBSD ARM64 images can be downloaded: Generic NetBSD 64-bit image for Raspberry Pi 3 and NVIDIA Tegra X1 Two images for FriendlyELEC boards namely NanoPi NEO2 and NEO Plus2 boards Five images for the following Pine64 boards and hardware platforms Pine A64/A64+ Pine A64-LTS / Sopine with baseboard Pine H64 Pinebook laptop ROCK64 (ROCK64Pro not yet supported) The supported hardware matrix shows most features are supported, but there are still a few things missing such as GPU, crypto and MIPI CSI on all platforms, USB OTG is still experimental, and PCIe support is …

Red Hat Enterprise Linux 7.4 Now Fully Supports Arm servers

When hardware vendors announced Arm based servers they also claim support for operating systems such as Ubuntu 16.04 LTS and Red Hat Enterprise Linux, so I assumed software support was more or less where it needed to be with regards to Arm server. But apparently, it may not have been so, as Red Hat only announced full support for Arm servers in Red Hat Enterprise Linux for ARM a few days ago. It also started with SBSA (Server Base System Architecture) specifications in 2014, that aimed to provide a single operating platform that works across all 64-bit ARMv8 server SoCs that complies with the said specification. Red Hat then released a developer preview of the OS for silicon and OEM vendors in 2015, and earlier this week, the company released Red Hat Enterprise Linux 7.4 for Arm, the first commercial release for this architecture. RHEL 7.4 for Arm come with Linux 4.11 kernel and support networking drivers from various vendors …

MACCHIATOBin based DIY ARM Desktop, DragonBoard 820c based DIY ARM Laptop (Video)

2017 may be the year of the (ARM based) Linux desktop, sort of. We’ve already seen GIGABYTE ARM development PC powered by a Socionext SC2A11 Synquacer 24-core ARM Cortex A53 processor that will be available in December, and apparently working fairly well already. But there are even more options, as Bernhard Rosenkränzer (Bero) from the Linaro Mobile Group, and unofficial Linaro superstar, has decided to create his own ARM based desktop and laptop, based on respectively MACCHIATOBin board with a Marvell ARMADA 8040 quad core Cortex  A72 processor, and DragonBoard 820c board with a Qualcomm Snapdragon 820 quad core Krait processor. Since MACCHIATOBin board complies with mini-ITX form factor, he could simply use off the shelf parts with a standard desktop case with power supply, NVIDIA or AMD Radeon graphics card, 16GB memory modules, and a 2 TB SSD drive. The AMD Radeon card fried due to overheating, so the demo was made with an NVIDIA card driven by Nouveau …

How ARM Nerfed NEON Permute Instructions in ARMv8

This is a guest post by blu about an issue he found with a specific instruction in ARMv8 NEON. He previously wrote an article about OpenGL ES development on Ubuntu Touch, and one or two other posts. This is not a happy-ending story. But as with most unhappy-ending stories, this is a story with certain moral for the reader. So read on if you appreciate a good moral. Once upon a time there was a very well-devised SIMD instruction set. Its name was NEON, or formally — ARM Advanced SIMD — ASIMD for short (most people still called it NEON). It was so nice, that veteran coders versed in multiple SIMD ISAs often wished other SIMD ISAs were more like NEON. NEON had originated as part of the larger ARM ISA version 7, or ARMv7, for short. After much success in the mobile and embedded domains, ARMv7 was superseded by what experts acknowledged as the next step in the evolution …

SolidRun MACCHIATOBin is Another Marvell ARMADA 8040 Networking Mini-ITX Board

We’ve already seen SolidRun is working on a Marvell ARMADA 8040 quad core Cortex A72 community board for networking and storage applications, but based on a picture taken at Linaro Connect, the company is also working on a similar board with extra connectivity options called MACCHIATOBin. Apart from the picture, there’s no info on the web about this board, so we’ll have to derive specs from the photo, the community board features, and info provided by Marcin Juszkiewicz, so all details are preliminary and subject to change: SoC – ARMADA 8040 (88F8040) quad core Cortex A72 processor @ up to 2.0 GHz System Memory – 1x DDR4 DIMM up to 16GB RAM Storage – 3x SATA 3.0 port + micro SD slot Connectivity – 1x Gigabit RJ45 port, 1x SFP SGMII @ 2.5Gbps, 2x 10Gbps copper (RJ45) with auto switchover to dual SFP+ Expansion – 1x PCIe-x4 3.0 slot, Marvell TDM module header USB – 1x USB 3.0 port, 1x …
