Software Matters, or How SinoVoIP Crippled Banana Pi M2+ Performance.

The most common way to use a development board is to simply go to the manufacturer website, and download the images from there. They are the ones who made the hardware after all, and they should be the most knowledgeable about their platform. But it may not always be true as tkaiser found out when he ran some Phoronix benchmarks on Banana Pi M2+ (aka BPI M2+) board with SinoVoIP (the manufacturer), Armbian, and Raspbian images. The results speak for themselves. The last three columns are what is of interest here, and in some benchmark Banana Pi M2+ is about 3 times slower with SinoVoIP image compared to Armbian, while with others the performance is quite similar. John The Ripper password cracker benchmark shows a massive difference between distributions… … while FLAC audio encoding not so much. So what’s going on here? First Jon the Ripper is a multi-threaded applications, […]

Raspberry Pi 3, ODROID-C2 and Pine A64+ Development Boards Comparison

Raspberry Pi 3 and hardkernel ODROID-C2 launched the same day, and together with Pine A64/A64+, are the only ultra low cost (<$40) 64-bit ARM development boards available or soon-to-be available, so I’ve decided to make a comparison of the three boards the same way I did with ~$10 boards with a Raspberry Pi Zero, C.H.I.P, and Orange Pi One comparison. I’ve used features of Pine A64+ instead of Pine A64 since features and price are closer to the other two boards. Text highlighted in green means a board is clearly better than the other two for a given features, while a red highlight means it’s the weakest of the three. Raspberry Pi 3 ODROID-C2 Pine A64 Plus Processor Broadcom BCM2837 quad core Cortex A53 processor @ 1.2 GHz(4x ~2760 DMIPS) Amlogic S905 quad core Cortex A53 processor @ 2.0 GHz(4x ~4600 DMIPS) Allwinner A64 quad core Cortex A53 processor @ […]

Raspberry Pi 3 Board is Powered by Broadcom BCM2837 Cortex A53 Processor, Sells for $35

Raspberry Pi 3 board was first found on the FCC website, and thanks to various other leaks we had a pretty good idea of the board specifications including a Broadcom 64-bit ARM processor coupled with 1GB RAM, WiFi and Bluetooth, as well as basically the same features and ports as Raspberry Pi 2 Model B. But with the fourth anniversary of the Raspberry Pi Model 1 board, Raspberry Pi 3 has now officially been launched, and you can now purchase the board for $35. Raspberry Pi 3 specifications: SoC – Broadcom BCM2837 64bit ARMv8 quad core Cortex A53 processor @ 1.2GHz with dual core VideoCore IV GPU @ 400 MHz supporting OpenGL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode. Capable of 1Gpixel/s, 1.5Gtexel/s or 24GFLOPs with texture filtering and DMA infrastructure System Memory – 1GB LPDDR2 Storage – micro SD slot Video & Audio Output – HDMI 1.4 […]

Open Source Operating Systems News – Maru OS, Zephyr, ReactOS, Tizen 3.0, and Raspbian

There have been several news related to open source operating systems in the last couple of weeks including Maru OS to run Debian on Android, Zephyr Project real-time OS managed by the Linux Foundation, ReactOS an open source port of Windows XP, and Raspberry Pi boards are getting a Tizen 3.0 port, as well as a new Raspbian release. Maru OS – Mobile <-> Desktop Convergence Maru OS mobile operating system is supposed to do what Ubuntu convergence promised: it runs in mobile mode on the go with Android Lollipop mobile OS, once you connect the phone to an HDMI screen, and pair Bluetooth keyboard and/or mouse, it will switch to desktop mode running Debian Linux. The downside is that so far it a single developer (Preetam D’Souza) worked on it, and the beta version only works on Nexus 5 smartphone. However, since the project went viral, dozen of other […]

Orange Pi One Quad Core ARM Linux Development Board Launched for $9.99

Orange Pi One board was unveiled at the end of last year as a cheaper alternative to Orange Pi PC with Allwinner H3 quad core processor, 512 MB RAM, an Ethernet Port and HDMI output. I’ve already compared it to C.H.I.P and Raspberry Pi Zero, and found that it was both much more powerful and cheaper to use as an Internet connected board with HDMI output than the two more well-known competitors. The good news is that Orange Pi One is now selling for $9.99 + shipping on Aliexpress, which in my case would be $13.38 in total. Orange Pi One technical specifications: SoC – Allwinner H3 quad core Cortex A7 @ 1.2 GHz with an ARM Mali-400MP2 GPU up to 600 MHz System Memory – 512 MB DDR3 Storage – micro SD card slot Video & Audio Output – HDMI with CEC support Connectivity – 10/100M Ethernet USB -1x […]

Raspberry Pi Zero, C.H.I.P, and Orange Pi One Boards’ Features and Price Comparisons

With Raspberry Pi Zero, Next Thing C.H.I.P, and Orange Pi One, we now have have three ARM Linux development boards selling (now or soon) for less than $10 excluding shipping and taxes. So I’d think it would be interesting to compare the features of the boards, and prices for different use cases. The comparison table below shows the three boards features side-by-side with items highlighted in green for the best or extra features, and in red for the weakest. Some cells will have to be filled later as data is currently not available (marked TBD). Raspberry Pi Zero C.H.I.P Orange Pi One Processor Broadcom BCM2835 single core ARM11 processor @ 1GHz (~1250 DMIPS) Allwinner R8 Cortex A8 processor @ 1 GHz (2000 DMIPS) Allwinner H3 quad core Cortex A7 processor @ 1.2 GHz (4x 2280 DMIPS) GPU VideoCore IV ARM Mali-400 ARM Mali-400MP2 Video Decoding 1080p30 for H.264, MPEG2* and […]

DietPi is Lightweight, Easy to Use Debian Based Distribution for Raspberry Pi, ODROID, and Orange Pi Boards

Raspberry Pi, Hardkernel ODROID, and Orange Pi are some of the most popular and cost effective development boards on the market today, and one British developer, going under Fourdee nickname, has released a lightweight distribution called DietPi working for all Rasbperry Pi boards, ODROID-C1(+), ODROID-XU3/XU4, and Orange Pi PC, with Orange Pi 2 and Orange Pi Plus support coming soon, as well as a VMWare virtual machine also available for evaluation. The compressed downloads are about 80 to 100MB depending on the target, the image that can be dump with dd or Win32DiskImager requires a 1GB or greater micro SD card as the image itself is about 500MB large, Internet access (Ethernet or Wifi), and optionally a USB Drive to allow installation on a USB drive for better performance, which of course does not apply if you have an eMMC module with your ODROID board. The image also contains some […]

Raspberry Pi Zero is a $5 Board Based on Broadcom BCM2835 Processor

The Raspberry Pi board had some serious competition price-wise with products such as Orange Pi PC, NanoPi, or even C.H.I.P, but the Raspberry Pi foundation has lowered the price barrier even further with the Raspberry Pi Zero board, based on the same processor as the original Raspberry Pi (model 1) boards but clocked at a higher speed, and in a much smaller form factor, and launching at an unbeatable price: $5. Raspberry Pi Zero specifications: Processor – Broadcomm BCM2835 ARM11 processor @ 1GHz with VideoCore IV GPU System – 512MB RAM Storage – microSD slot Video Output – mini HDMI port and composite video (via 2 unpopulated pins) USB – 2x micro USB OTG ports for data and power Expansion – 40-pin through-holes Power Supply – 5V via micro USB port Power Consumption – 0.5-0.7W (100-140mA at 5.09V) according to Raspi.TV Dimensions – 65mm x 30mm x 5mm The board […]
