Adafruit Launches Raspberry Pi Starter Pack for $69.95

The Raspberry Pi is supposed to be great for hardware prototyping, but you may not know where to start and/or depending where you live it might be difficult to buy the small components needed at a decent price. That’s where Adafruit Raspberry Pi starter pack comes into play. It includes a case, some cables and power supplies, as well as a breadboard and a whole bunch of components. The package includes: Adafruit clear acrylic Pi Box USB Micro-B Cable to connect the Raspberry Pi to a power source 5V 1A power adapter USB TTL console cable to be used to access the serial console. Useful to debug the kernel or if you run your device without display and/or network. 4GB SD Card Adafruit Pi Cobbler kit with GPIO cable for connection to the GPIO/I2C/SPI/Power pins. USB microSD card reader for loading the image onto the SD card. Large full-size clear […]

WordPress for Raspberry Pi using Nginx and MySQL

I’ve been wondering how the Raspberry Pi would handle WordPress. I’ve found some instructions using Apache 2, but this may not be the best server to use for this type of low-end hardware. nginx server requires less resources, and as it is what I already setup for this blog, I decided to give it a try on the Pi. I’ll provide all the detailed steps I followed below, but you can also download the compressed SD card image (113 MB), uncompress it and copy it to an SD card the usual way. After the system boots, find your Raspberry Pi’s IP address, type it in your PC’s browser, and you should see the page pictured below. If you want to login to the dashboard, the username is “admin” and the password “raspberry”. Instructions to Install WordPress on Raspberry Pi You can use your default Debian Linux distribution (e.g. Raspbian) if […]

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, […]

84 MB Minimal Raspbian ARMHF Image for Raspberry Pi

Many embedded systems applications do not require a desktop environment or graphical interface on the screen (e.g. server), and you may want to only install the files you really need on the SD card either to reserve as much space as possible for data and/or your program or to reduce costs. After searching for a minimal image based on Raspbian ARMHF distribution for the Raspberry, I could only find Linux Systems minimal image based on the Alpha version of the Raspbian Wheezy. Their compressed image is 109 MB in size, has a custom kernel, sshd and ntpd are enabled, but the wireless tools were deleted, and at the time the swap was located in another partition instead of a file inside the rootfs. The uncompress rootfs is about 414 MB (as reported by df -h when mounted as a loop device). I decided to prepare a minimal image myself based […]
