NanoPi Duo Quick Start Guide – Ubuntu, Breadboard, Mini Shield & mSATA SSD

As far as I know NanoPi Duo is the only quad core ARM Linux development board that can fit on a breadboard. We’ve already seen it’s much smaller than Raspberry Pi Zero, and the company offer a mini shield exposing USB ports, Ethernet, a few I/Os, and an mSATA slot in in NanoPi Duo Starter Kit Review – Part 1: Unboxing and Assembly. I’ve finally played with it this week-end, and will report what I had to do to blink a LED when connected to breadboard, and my experience using the mini shield with an mSATA SSD, WiFi connectivity, and cooling under load. Flashing Ubuntu 16.04.2 firmware image to NanoPi Duo As with many other Allwinner development boards, you should first check if Armbian is available for the board. NanoPi Duo is not supported, but it’s said to work with Orange Pi Zero image minus support for WiFi. Since the […]

Emcraft Releases Linux BSP for NXP i.MX RT1050 Cortex M7 Evaluation Board

NXP iMX RT series is a family of ARM Cortex M7 processors clocked at 600 MHz, making the solution a “crossover embedded processor” bridging the gap between real-time capabilities of micro-controllers and the performance of application processors. This week, NXP provided some benchmark numbers for i.MX RT1050 processor, which delivers a CoreMark score of 3020, DMIPS of 1284, and 20ns interrupt latency at 600 MHz, which means it could be a good candidate for embedded Linux, and Emcraft Systems has just released a uCLinux BSP for the NXP i.MX RT1050 EVK board. The BSP features U-Boot v2017.09-rc1, Linux Kernel 4.5 with relevant device drivers such as key I/O interfaces, Wi-Fi, SD card, LCD, etc…, and GNU development tools such as a GCC 4.7 toolchain, GDB, and so on. The company has made a demo with a GUI application designed with Crank Software’s Storyboard Suite, and running in Linux on the […]

Purism Librem 5 Open Source Linux Smartphone Meets its 1.5 Million Dollars Funding Target

Back in the summer, we reported about Purism Librem 5, a privacy-focused, open source Linux smartphone. The hardware has not been developed yet, at the time the company was still considering either i.MX 6 Cortex A9 processor or i.MX8 Cortex A53 processor for the phone, and asked for 1.5 million dollars in their self-managed crowdfunding campaign to get the phone delivered in 2019. The project was interesting but with the current status for the project, amount to be raised, and delivery timeline, it was a long shot. But it turns out there’s some demands for smartphones outside of Android and iOS ecosystem, and since then, KDE and the GNOME foundation have joined the project leading to more coverage & people getting involved, and Librem 5 phone is now fully funded with 13 days to go. The processor will likely be NXP i.MX 8M Quad quad core Cortex A53 SoC, as […]

Mecool VS-RK3399 Board Linux Benchmarks

I’ve just showed how to install Debian, and build a Linux image from source on VS-RD-RK3399 board (aka Mecool VS-RK3399) last week-end, but at the time I did not run any benchmarks on the board. We already have plenty of benchmarks for Rockchip RK3399 in Android, so instead I started by installing the latest Phoronix Test Suite in Debian:

sudo apt install php-cli php-gd php-xml php-zip 
wget http://phoronix-test-suite.com/releases/repo/pts.debian/files/phoronix-test-suite_7.4.0_all.deb 
sudo dpkg -i phoronix-test-suite_7.4.0_all.deb

sudo apt install php-cli php-gd php-xml php-zip

wget http://phoronix-test-suite.com/releases/repo/pts.debian/files/phoronix-test-suite_7.4.0_all.deb

sudo dpkg -i phoronix-test-suite_7.4.0_all.deb

… and ran the tests I did on NanoPi NEO 2 earlier:

phoronix-test-suite benchmark 1704029-RI-1704017RI65

1	phoronix-test-suite benchmark 1704029-RI-1704017RI65

For whatever reasons OpenSSL and Mafft failed to download, but we still have the other benchmarks to compare with. Note that the Debian image is likely not optimized, and while the system runs an Aarch64 kernel, the rootfs is only 32-bit, which may have affected some of the benchmarks.

Banana Pi BPI-W2 is a Features-Packed Realtek RTD1296 Development Board

I’ve reviewed several Realtek RTD1295 platforms with Zidoo X9S and Eweat R9 Plus, and I was generally impressed by the storage, Ethernet, and WiFi performance. 4K video playback was good too, as long you don’t have any 4K H.264 videos at 30 fps or more. Most devices would also run Android and OpenWrt side-by-side bringing the best of both operating for respectively apps & multimedia, and server functions. HDMI input – with PVR, time-shifting and PiP functions – was also a bonus, However so far, nobody cared to design a maker board powered by RTD1295 processor. Since then we’ve learned Realtek was working on RTD1296 processor with even more Gigabit Ethernet, USB 3.0, and SATA interfaces, and SinoVoIP has now designed a board based on the SoC called Banana Pi BPI-W2. Banana Pi BPI-W2 preliminary specifications: SoC – Realtek RTD1296 quad core Cortex A53 processor with ARM Mali-T820 MP3 GPU […]

Short Demo with 96Boards SynQuacer 64-bit ARM Developer Box

Even if you are working on ARM platforms, you are still likely using an Intel or AMD x86 build machine, since there’s not really a good alternative in the ARM world. Linaro talked about plans to change that at Linaro Connect Budapest 2017 in March, and a few days ago, GIGABYTE SynQuacer software development platform was unveiled with a Socionext SynQuacer SC2A11 24-core Cortex-A53 processor, and everything you’d expect from a PC tower with compartment for SATA drives, PCIe slots, memory slots, multiple USB 3.0 ports, and so on. The platform was just demonstrated a Linaro Connect San Francisco right after Linaro High Performance Computing keynotes by Kanta Vekaria, Technology Strategist, Linaro, and Yasuo Nishiguchi, Socionext’s Chairman & CEO. If you have never used a system with more than 14 cores, you’d sadly learn that the tux logos at boot times will only be shown on the first line, skipping […]

Allwinner SoCs with Mali GPU Get Mainline Linux OpenGL ES Support

OpenGL ES support in Linux for ARM SoC is usually pretty hard to get because of closed source binary blobs coupled with the manufacturers focus on Android. Workarounds include open driver projects such as Freedreno for Qualcomm Adreno GPU, Nouveau for Tegra, or Etnaviv for Vivante GPUs, as well as libhybris library that converts Linux calls into Android calls in order to leverage existing Android GPU binary blobs. Allwinner processors relies on either PoverVR or ARM Mali GPU, and the former does not have any open source project, while some work is still being going for the latter with Lima project, but it’s not ready yet. That means so far, you’re only option was to use libhybris for either GPU family. The good news is that Free Electrons engineers have been working on OpenGL ES support for ARM Mali GPU for Allwinner processor, and have been allowed to release the […]
