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 […]

$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 […]

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 […]
