$60 MarsBoard RK3066 (Partially) Open Source Hardware Development Board Supports Android & PicUntu

Until now if you wanted a low cost Rockchip development board you’d have to go with Radxa Rock (Quad core RK3188) or WaxBerry Pi2 (Dual core RK3066). Thanks to Haoyu Electronics , the company who made MarsBoard A10, there’s now another option with MarsBoard RK3066 powered by Rockchip RK3066 dual core Cortex A9 SoC with 1 to 2 GB RAM, 4 to 8 GB Flash and lots of ports and expansion connectors. MarsBoard RK3066 is composed of a baseboard (SOM-RK3066) and a computer on module (CM-RK3066) with the following specifications: CM-RK3066 Computer-on-Module: SoC – Rockchip RK3066 dual core ARM Cortex A9 @ 1.6Ghz + Mali-400MP4 GPU System Memory – 1GB DDR3 SDRAM up to 2GB Storage – 4GB Nand Flash & eMMC FLASH Power Management Unit – TPS659102 Misc – TX indicator LED use for debug, Power Indicator LED 10/100M Ethernet PHY – LAN8720A SOM-RK3066 Baseboard: Storage – micro SD […]

Raspberry Pi Gets Open Source 3D Graphics Drivers and Documentation

The Raspberry Pi was launched 2 years ago, and for its birthday, Broadcom decided to release documentation and open source OpenGL ES 1.1 and 2.0 driver for the Videocore IV GPU.  You may remember the Raspberry Pi Foundation already release an open source GPU driver in 2012, but this was only for the part running on the ARM11 core for Broadcom BCM2835 SoC, which is just a few hundred lines of code long, and communicates with a binary blob which does all the work in the GPU itself. This new release however goes much further with a 111 page document entitled “VideoCore IV 3D Architecture Reference Guide“, and open source driver for the 3D System of the GPU. Strangely the release is however not for BCM2835, but instead BCM21553. Broadcom clearly has the source for BCM2835 too, so this must have been made for legal reasons. VideoCoreIV packs a lot […]

AMLogic S802 / M802 Android 4.4 SDK, Documentation and Reference Schematics Are (Almost) Available

We’ve seen in the past AMLogic sometimes pushes some updated GPL software releases on their Open Linux website. So I went to have a look a few days ago, and to my surprise they already had instructions to download and build Android 4.4 for AMLogic M802 (Tablet) and S802 (STB), “user’s guides”, as well as links to reference schematics for the tablets… Nice!!! I started with 4.4_ReleaseInfo for “Mbox” (S802), which explains how to get the SDK release on 2014-01-27 (kk-amlogic-20140127):

Unfortunately the joy stopped right there, as you need to send your SSH public key to your representative. I’ve just done that, and sent an email to support [at] amlogic.com, and mbox-android [at] amlogic.com on Sunday, and I have yet to gain access. I’ve found the “mbox-android” email in from Mbox page (similar to screenshot above) in a field right of “reference schematics” column, which has been removed […]

STMicro Unveils $10 mbed-enabled and Arduino Compatible Nucleo Development Boards

STMicro already announced a $24 NFC development kit a few days ago, and they’ve now announced new ultra low cost STM32 development boards. STMicro Nucleo development boards are based on different STM32 MCU based on ARM Cortex M0, M3 and M4, feature Arduino headers, and are supported by mbed platform. There are currently four boards available: NUCLEO-F401RE – Based on STM32F401RET6 ARM Cortex M4 MCU @ 84 MHz with 512KB flash memory, 96 KB SRAM NUCLEO-F030R8 – Based on STM32F030R8T6 ARM Cortex M0 MCU @ 48 MHz with 64KB flash memory, 8KB SRAM NUCLEO-F103RB – Based on STM32F103RBT6 ARM Cortex M3 MCU @ with 128KB flash memory, 20 KB SRAM NUCLEO-L152RE – Based on STM32L152RET6 ARM Cortex M3 MCU @ 32MHz with 512KB flash memory, 32KB SRAM All four boards share the following specifications: STM32 microcontroller with LQFP64 package Two types of extension resources Arduino Uno Revision 3 connectivity STMicroelectronics […]

Intel Bay Trail Graphics Overview – FOSDEM 2014

Bay Trail SoCs are new low power Intel ICs for tablets (Bay Trail-T, Z3000 series), mobiles (Bay Trail-M, N2800, N2900 and N3500 series), desktops (Bay Trail-D, J1800, J1900 and J2900 series) and embedded / industrial platforms (Bay Trail-I, E3800 series). Many Atom processors used to features PowerVR GPU, but it has now been replaced by Intel HD graphics in Bay Trail SoC. Jesse Barnes, working at Intel on software and drivers for Intel graphics devices, gives a presentation about Bay Trail SoCs with a focus on graphics. After an overview, and some ARM bashing regarding performance (Nvidia Tegra 4 and Qualcomm Snapdragon 800), and even power consumption (Tegra 4 only), he describe further details about Intel HD graphics found in the new Intel processors. Everything is basically in mainline, and you’ll need Linux 3.10 or greater, Mesa 9.2 or greater, and libva 1.2.1 or greater for proper support. Some initial […]

AllWinner Linux-sunxi Community Presentation and Status Report – FOSDEM 2014

Oliver Schinagl, a member of linux-sunxi community working on open source kernel and bootloader for AllWinner SoCs, has given a presentation of the community at FOSDEM 2014 to give an overview, and show what progress has been made to date. I’ll write a summary in this post, but if you want to watch the video and/or access the slides scroll down at the bottom of the post. After explaining what sunxi is, and introducing himself, he gave some information about AllWinner and their SoCs: Founded in 2007 in Zhuhai, Chiang now with 550 employees including 450+ engineers 15% market share in 2013 for tablet SoCs, only behind Apple. Products: F-series SoC (2010), A10 (2011), A13, A10s (2012), and A20 (2013). (cnsoft He skipped A31(s) and A80 here as they are not really supported by the community). They list “Open Source Source” and “GPLv3” in their marketing materials although they clearly […]

DragonBox Pyra Open Source Handheld Game Console To Feature TI OMAP5432 SoC.. or AllWinner A80, or Intel Bay Trail, or Qualcomm Snapdragon…

Pandora is an open source handheld console which development started as far back as 2007. The project has had ups and downs, and some people have yet to receive the device they pre-ordered. As many components are now more difficult to source, Pandora has reach end-of-life, as Pandora 2 is now being developed with a subset of the original team, but has been renamed to DragonBox Pyra to start afresh. The new version aims to take to the good aspects of the original Pandora, and improve on the bad ones, so that DragonBox will have a faster hardware with a better looking case and better control. Here are the specifications listed on the project website: SoC – Texas Instruments OMAP 5432 SoC with 2x ARM Cortex-A15 @ 1.7Ghz with NEON SIMD, 2x ARM Cortex-M4, Imagination Technologies PowerVR SGX544-MP2 GPU for 3D graphic, and Vivante GC320 GPU for 2D graphics System […]
