Raspberry Pi 2 / ODROID C1+ Development Boards Comparison

Raspberry Pi 2 Model B board has just been released, and although it’s not a direct answer to ODROID-C1, as Broadcom started the design for BCM2836 SoC for RPI2 a long time ago, both low cost development boards have similar specifications, with a quad core processor, 1GB RAM, Ethernet, and four USB ports, as well as the exact same price: $35. So I’ve decided to compare both in details to find out the actual differences, and which one may be more suitable to a particular application. Let’s get straight to the comparison table. [Updated on November 24 to use ODROID C1+ instead of ODROID C1] Hardkernel ODROID C1+ Raspberry Pi 2 Model B Comment Processor Amlogic S805 quad core Cortex A5 @ 1.5 GHz (Overclockable to 1.7 GHz or more) Broadcom BCM2836 quad core Cortex A7 @ 900 MHz (Overclockable to 1.1GHz or more) Despite the architecture advantage for Cortex […]

Linaro 15.01 Release with Linux 3.19 and Android 5.0

Linaro has just announced the first release of the year with Linux 3.19-rc3 (baseline), Linux 3.10.65 and 3.14.29 (LSK), Android 5.0.2, and Ubuntu Linaro Utopic. Changes seem to have focused on ARM, Qualcomm, and HiSilicon hardware platforms such as Juno, and IFC6410, and some work has been done on Debian ARM64 rootfs. Here are the highlights of this release: Linux Linaro 3.19-rc5-2015.01 GATOR topic updated to version 5.20.1 builddeb topic: fixes for the dtb files location changes in 3.19 (vendor subdir introduced) updated integration-linaro-vexpress64 topic by ARM LT (FVP Base and Foundation models, and Juno support) updated topic from Qualcomm LT (IFC6410 board support) updated topic from HiSilicon LT (Hi36xx, HiP04, and X5HD2 families support) updated LLVM topic (uses the community llvmlinux-latest branch) Included ILP32 patch set v3 rebased on 3.19-rc5. Initial tests using syscalls LTP tests are done: msgctl07 stalls when using ILP32 userland (no stall with LP64 userland). […]

Online Labs pBox (C1 Node) is a mini ARM Server with 4 Gigabit Ethernet Ports, mSATA and mPCIe Slots

Online Labs, a subsidiary of Iliad (free), recently launched hosting services with dedicated ARM servers based on Marvell processor with modules they call C1. The company has decided to design a baseboard (pBox) for C1 module, and, as I understand it, plans to sell it to the public. It’s an exciting development for those who are looking for affordable and tiny purpose built Linux ARM servers. Preliminary C1 Node / pBox mini server specifications (based on C1 specs and bits of information gathered online): SoC – Marvell Armada 370/XP quad core ARMv7 processor @ up to 1.2 GHz System Memory – 2GB RAM Storage – 256 MB NAND flash + mSATA slot + eSATA port + micro SD slot Connectivity – 4x Gigabit Ethernet ports USB – 1x micro USB port Expansion – mini PCie, 1x 20-pin header for expansion (no details yet) Debugging – 20-pin JTAG connector Power Supply […]

X29 Intel Celeron J1800 / J1900 mini PC Sells for $125 and Up

Today, somebody asked me to test 4K output on Intel Atom Z3735F, but I can’t do that since the platform only supports 1080p. As I just posted my unboxing of MeLE PCG03 mini PC, I noticed several ICs where added for extra functionalities, and people also started to complain about lack of Gigabit Ethernet, Fast Ethernet via a USB bridge, no USB 3.0, and no SATA. That’s what happens when you use a Tablet SoC in a mini PC, but if you’re ready to pay a little more, you could still get a mini PC with a proper desktop processor (Bay Trail-D) including SATA, USB 3.0, and Gigabit Ethernet (maybe) for about $125 (shipped) with X29-J1800 computer powered by Intel Celeron J1800 (10W TDP). That’s the price for the barebone system without RAM or storage, and if you want a complete system with 32GB eMMC and 4GB RAM the price […]

Linux 3D GPU Acceleration Demo on Rockchip RK3288 based Firefly Board

Several devices and development boards based on Rockchip RK3288 processor already support Linux, usually with images based on Ubuntu, including Ugoos UM3 / UT3, Open Hour Chameleon, and Firefly-RK3288 among others. What these images lack however, is support for 2D and 3D graphics acceleration with the GPU, and hardware video decoding/encoding with the VPU. But Jas-hacks has made some progress with 3D graphics support. He has managed to add GPU acceleration via EGL/OpenGL ES bringing 3D acceleration to the platform, but 2D support is not there yet, meaning X11 still heavily relies on software rendering. But the implementation is still good enough to run the usual es2gears and glmark2-es2 benchmarks. as well as some WebGL demos in Chromium. Performance is currently underwhelming, with 50 points in glmark-es2, even a bit lower than the score (54 points) I got with ODROID-X board powered by Exynos 4412 SoC with a Mali-400MP4 GPU, […]

Ugoos UT3S is an Update to UT3 Android & Ubuntu TV Box with a Fan

Many people like ARM based media player because most of them run Android providing access too many apps available via Google Play Store, a similar experience to what they got used with phones and tablets, and also because they are small, inexpensive, and fanless. However, the latest ARM processors such as Rockchip RK3288, can get really hot, so most of the time CPU frequency needs to be limited to avoid overheating and stability, which reduces performance. Which may be why, Ugoos decided to launch UT3S mini PC, an upgrade to UT3 mini PC with a mini Fan placed on top of a larger heatsink. Ugoos UT3S specifications and look remain very similar to the original model: SoC – Rockchip RK3288 quad core CortexA17 @ 1.80 GHz + Mali-T764 GPU with support for OpenGL ES 1.1/2.0 /3.0, and OpenCL 1.1 System Memory – 2GB to 4GB DDR3 Storage – 16GB or […]
