96-Core NanoPi Fire3 Boards Cluster is a DIY Portable Solution to Teach or Develop Distributed Software

96-Core NanoPi Fire3 Cluster

Nick Smith has been messing around with clusters made of Arm boards for several years starting with Raspberry Pi boards, including a 5-node RPI 3 cluster, before moving to other boards like Orange Pi 2E, Pine A64+, or NanoPC-T3. His latest design is based on twelve NanoPi Fire3 boards with 8 cores each, bringing the total number of cores to 96.  The platform may not be really useful for actual HPC applications due to limited power and memory, but can still be relied upon for education and development, especially it’s easily portable. Nick also made some interesting points and discoveries. It’s pretty with shiny blinking LEDs, and what looks like proper cooling, and the cluster can deliver 60,000 MFLOPS with Linpack which places it in the top 250 faster computers in the world! That’s provided we travel back in time to year 2000 through 🙂 By today’s standard, it would be rather slow, but that’s an interesting historical fact. Nick …

TECHBASE ModBerry​ M300 IoT Gateway Adds Support for NanoPi and Orange Pi Allwinner H5 Boards

Announced at the end of last year TECHBASE launched the ModBerry​ M300, a Linux IoT gateway powered by FriendlyELEC NanoPi NEO board equipped with Allwinner H3 Cortex A7 processor. The company has now made four extra variants of the gateway with Allwinner H5 quad core Cortex A53 based development boards from FriendlyELEC and Shenzhen Xunlong: Modberry M300 N2 – Based on NanoPi NEO2 Modberry M300 N2+ – Based on NanoPi NEO Plus2 adding 8GB eMMC flash, WiFi & Bluetooth 4.0, and an extra USB port over the N2 model Modberry M300 O1 – Based on Orange Pi Zero Plus Modberry M300 O2 – Based on Orange Pi Zero Plus2 adding 8GB eMMC flash, HDMI, one extra USB port, and Bluetooth 4.0 over the O1 model, but falling back to 10/100 Ethernet, while all three models above come with Gigabit Ethernet To avoid confusion, the original NanoPi NEO model has changed name to ModBerry M300 N1. The specifications summary / comparison …

Linux 4.15 Release – Main Changes, Arm and MIPS Architectures

Linus Torvald has released Linux 4.15 last Sunday: After a release cycle that was unusual in so many (bad) ways, this last week was really pleasant. Quiet and small, and no last-minute panics, just small fixes for various issues. I never got a feeling that I’d need to extend things by yet another week, and 4.15 looks fine to me. Half the changes in the last week were misc driver stuff (gpu, input, networking) with the other half being a mix of networking, core kernel and arch updates (mainly x86). But all of it is tiny. So at least we had one good week. This obviously was not a pleasant release cycle, with the whole meltdown/spectre thing coming in in the middle of the cycle and not really gelling with our normal release cycle. The extra two weeks were obviously mainly due to that whole timing issue. Also, it is worth pointing out that it’s not like we’re “done” with …

Year 2017 in Review, Top 10 Posts, and Some Fun Stats

2017 is coming to an end, and as I do every year, I’ll take a look back at the year that was on CNX Software. The pace of development boards launches has not slowed down this year, and we get an even wider range from the low-end with Orange Pi or NanoPi boards, to much more powerful ARM boards, and some new entrants like Libre Computer. The same is true for TV boxes, most of which now support 4K HDR, ranging from ultra cheap models selling for less than $20 to higher end Android TV boxes, while mini PCs were dominated by Intel Apollo Lake models, although some Cherry Trail products were also launched. Processor-wise, Amlogic launched more Amlogic S905X derivatives with S905W/S905D/S905Z, which are popular in the TV box market. Rockchip’s most interesting processor this year was RK3328 quad core Cortex A53 processor designed for 4K HDR Android TV boxes, but also popular with single board computers thanks to …

NanoPi NEO Core and NEO Core2 Allwinner H3/H5 Systems-on-Module Launched for $7.99 and Up

FriendlyELEC has launched many cool NanoPi development boards such as NanoPi NEO2, NanoPi A64, or more recently NanoPi Duo based on Allwinner H- or A- series ARM processors, as well as some models based on Samsung/Nexcell or Amlogic SoC. The company has now launched two other NanoPi products that are a bit different since they are systems-on-module – or could even be considered minimal development boards – with namely NanoPi NEO Core powered by Allwinner H3 quad core 32-bit processor, and NanoPi NEO Core2 based on Allwinner H5 quad core 64-but processor. NanoPi NEO Core Specifications: SoC – Allwinner H3 quad core ARM Cortex-A7 processor up to 1.2GHz with Mali-400MP GPU System Memory – 256MB or 512MB DDR3 RAM Storage – NC/8GB/16GB/32GB eMMC flash, micro SD slot USB – 1x micro USB OTG port also used for power input Expansion – 2x 2.54mm pitch 24-pin headers, 1x 2.54mm pitch 20-pin header exposing: Connectivity – 10/100M Ethernet USB – 3x USB …

Armbian v5.35 Released with Linux 4.13, U-boot v2017.09, New Boards Support

Armbian v5.35 has been released last Friday as a major update that brings Linux mainline kernel to version 4.13, U-Boot mainline to version v2017.09, adds support for 7″ Raspberry Pi display, Realtek WiFi drivers (mainline), and new stable hardware support for NanoPi Duo, Pinebook, and Orange Pi R1. Some other boards got experimental support, including Le Potato, NanoPi NEO 2, Orange Pi Zero Plus, Orange Pi Zero Plus 2 (H5). The desktop version of the images gets a full featured XFCE terminal, OpenVPN connector, a new wallpaper, and various other changes and fixes. armbian-config is normally used to configure the board for example networking configuration, but the utility has become even more useful with support for Hotspot, Bluetooth, SSH server configuration, swtich between stable & beta builds and between kernel applications, adds the ability to start an RDP server, and install third party software such as SAMBA, OpenMediaVault, PiHole, Transmission BT, and so on. If you have an existing installation, …

TECHBASE ModBerry​ M300 Linux IoT Gateway ​is Powered by NanoPi NEO Board

Linux 4.14 Release – Main Changes, ARM & MIPS Architecture

Linus Torvalds has announced the release of Linux 4.14: No surprises this week, although it is probably worth pointing out how the 0day robot has been getting even better (it was very useful before, but Fengguang has been working on making it even better, and reporting the problems it has found). Sure, some of the new reports turned out to be just 0day doing things that just don’t work (ie KASAN with old gcc versions, but also doing things like loading old ISA drivers in situations that just don’t make sense – remember when you couldn’t even ask if the hardware existed or not, and just had to know), but even then it’s been all good. The appended shortlog is obviously only for the (small) haul since rc8, and it really is tiny. Not very many commits, and they are small. The biggest thing that stands out in the diffstat is the “leaking_addresses” perl script, which is actually under active …
