RasPiComm – Raspberry Pi Expansion Board

Daniel Amesberger has designed a tiny expansion board called the RasPiComm to make use of the extension header of the Raspberry Pi board. It connects to the RPi in a similar way to the shields for the Arduino board. The board comes with the following extensions: RS-485 port – Mainly used to control stepper motors. RS-232 (‘serial’) port – It can be used to access the serial console over “/dev/ttyAMA0″ serial device, which can be very useful for headless systems. 5 inputs connected to an onboard joystick and screw terminals 2 outputs (5V) with LEDs (green and red) also connected to screw terminals I2C connection – There are plenty of things you can do with I2C connections (Sensors, RTC, …), and Daniel successfully connected a tiny 128×64 I2C OLED display. Real time clock (RTC) with backup battery – Very useful for offline use if you need to keep track of the […]

HackBerry AllWinner A10 Board is Now Available for $60

The Hackberry “development board” is now available for sale on Miniand. This board powered by AllWinner A10 processor comes in 2 versions: 512 MB RAM version – Available now for $60 1GB RAM version – Available by the end of the month for $65. Both boards features a 4GB Flash, a SDHC slot, 2x USB 2.0 port, 10/100 Ethernet, Wi-Fi, HDMI & composite outputs,  headphone & microphone ports and a IR sensor. The good thing is that serial interface and FEL connectors will be soldered on the board for easy debugging and recovery. The FEL recovery port allows to reflash the board using Livesuit. As a side note, Henrik, a developer involved in Allwinner A10 software development, has done some work to reverse engineer FEL USB protocol, wrote a small program to enter into Livesuit mode with an SD card (Go to the bottom of the page section “Forcing FEL […]

AllWinner A10 Initramfs Support and Linaro 12.07 Image

An initramfs is a minimal root filesystem that is loaded at an early stage of the boot process, before the rootfs partition is mounted. This is optional but is now used by many Linux distributions such as Ubuntu in order to speed up boot time among others things. Up to recently, there was no support for this in the AllWinner A10 nightly builds, and there would be lot of error messages due to ureadahead process with Ubuntu, but I’ve changed that by: Using a boot.scr file (U-Boot Script) for each supported device in order to either follow the default init boot method or do an initramfs boot if uInitrd file is present in the FAT partition. Adding a script (a1x-initramfs.sh) to generate and install uInitrd initramfs in the rootfs. The initramfs can’t be generated at build time since the hardware packs are (mostly) distribution agnostic. If you want an initramfs, […]

$39 Variscite VAR-SOM-AM33 SoM Powered by TI Sitara AM335x

Variscite has announced a new system-on-module based on Texas Instruments Sitara Cortex A8 AM335x processors (AM3352 or AM3354) named VAR-SOM-AM33, which sells for as little as $39 US (in large quantities I assume). This SoM is available in commercial and industrial grades, and the company expects the module to be used in applications such as automotive, control systems, lighting, refining and processing. Here are the specs of this module: CPU – Texas Instruments AM335x Processor @ up to 720 MHz withPowerVR SGX530 GPU (AM3354 only) System Memory – 256MB 606MHz DDR3 Storage – 128 to 512MB SLC NAND Flash Display interface – LCD interface – Parallel RGB Supporting 1400×1050 24bit and4/5/8-Wire touch panel interface Audio – Line-in, line-out, stereo headphone out, digital microphone, analog microphone and S/PDIF Out Connectivity: 10/100Mbps Ethernet PHY 10/100/1000Mbps RGMII Wi-Fi 802.11 b/g/n (via TI WiLink 6.0) Bluetooth V4.0 + EDR (via TI WiLink 6.0) Interfaces: 2 […]

How To Root CX-01 Android mini PC

CX-01 is a cool low cost Android mini PC (as low as $40), but unlike many other Chinese Android device it is not rooted. Here are the instructions to root it: Download Unlock Root http://www.unlockroot.com/. NB: The download link does not appear to work right now, but the filename is unlockroot23.exe, so here are some alternative untested download links. Find Unlockroot\driver\android_winusb.inf in the directory where you install Unlockroot Open the file in a text editor, and add the following lines: For Win 7 (64-bit): [Google.NTamd64] 64-bit] ;TCC8920 %SingleAdbInterface% = USB_Install, USB\Vid_18D1&Pid_DEED&MI_01 %CompositeAdbInterface% = USB_Install, USB\Vid_18D1&Pid_DEED&Rev_0231&MI_01 For WinXP (32-bit): [Google.NTx86] ;TCC8920 %SingleAdbInterface% = USB_Install, USB\Vid_18D1&Pid_DEED&MI_01 %CompositeAdbInterface% = USB_Install, USB\Vid_18D1&Pid_DEED&Rev_0231&MI_01 Connect CX-01 to your PC via USB, it should then detect your new device. If it doesn’t simply press “fn” key on CX-01 TV Stick. Select the driver that you edited in Unlockroot\driver\android_winusb.inf Once the driver is installed, run unlockroot Press ROOT, then […]

Android 4.0 Running on Raspberry Pi with Hardware Acceleration

Eben of the Raspberry Foundation announced that a developer (Naren) has been working on a port of Android 4.0 for the Raspberry Pi, and the port already appears to be a an advanced stage with hardware-accelerated graphics and video working smoothly. The only major issue is the lack of support for AudioFlinger. The demo below shows Android 4.0 running in the Pi without audio as it’s not implemented yet. The UI is relatively smooth, and video playback and YouTube video streaming work pretty well. This is quite impressive considering the Raspberry Pi has less than 256 MB of memory available to the system, and I suppose they must have made some compromises to make this work. Moreover, I would expect that many applications won’t run properly due to the ARMv6 processor and low system memory. The source code and binary release are not available yet, as this port uses a […]
