OLPC XO 1.75 Hardware, Firmware and Software

OLPC demo’ed their 3rd generation laptop – OLCP XO 1.75 – based on Marvell Armada 610 at CES 2011. The good thing about this platform is that they opened most of it including the hardware, the software and for the first time the firmware. However, I found out it’s not so easy to find the hardware / software development information and source on the OLPC site, so I’ve decided to make a summary and provide links to the hardware, firmware and software for OLPC XO 1.75. OLPC XO 1.75 Hardware The XO-1.75 is powered by Marvell Armada 610 CPU (88AP610) with an ARM core clocked at 1Ghz. It has 1GB DDR3 SDRAM, 4GiB NAND Flash, a TFT display, an SD Card slot, Wi-Fi, a few USB ports and a camera. I believe the touchscreen is not part of the current hardware, but the block diagram below should be close to […]

Linaro: Embedded Linux for ARM

Linaro is a Not For Profit (NFP) engineering organisation that works on Linux based open source software and tools. The organisation focuses on the ARM platform, mainly ARM v7A architecture, for example ARM Cortex-A8 or dual-core Cortex-A9 processors and is sponsored by ARM, Freescale, IBM, Samsung, ST-Ericsson, and Texas Instruments. The purpose of Linaro is to reduce the number of different Linux kernel for the ARM platform. They plan on releasing tools and Linux kernel every 6 months. And after about 6 months of existence, with around 80 engineering staff, they managed to release their first public version: Linaro-10.11 on the 10th of November for TI OMAP4 Panda Board, IGEPv2, Freescale iMX51 and ST-E U8500 platforms. This release is based on Linux 2.6.35 kernel, GCC 4.4 toolchain and uBoot 2010.09. They released Linux 10.11 source code and tools, the hardware packs and the build instructions. Linaro also planned several technical […]

XIBO: An Open Source Digital Signage Server/Client

Today’s post will deal with Xibo (pronounced eX-E-bO), an open source, multi-display, multi-zone, fully scheduled digital signage solution. I’ll firstly give an overview and explain how to install the client and server in Windows XP. In another post, I’ll demo the system. The server can run on Windows or Linux and requires a web server (Apache / IIS), php5 and a MySQL database. The client can only runs on Windows 2000/Xp/Vista/7 and requires .NET Framework v3.5, Internet Explorer 7 or 8, Flash Player Version 9 or later, Windows Media Player 11 or later, Microsoft Powerpoint 2003 or later. As you can see from the client description, it won’t be able to run on Linux embedded systems, but it is still interesting to study this solution to see the content management flow, what this solution has to offer and how we get development idea from this solution. An embedded client based […]
