Google and Samsung Galaxy Nexus Android 4.0 Smartphone

Samsung and Google jointly announced the very first Android 4.0 (ICS) smartphone in Hong Kong. They did not get too original to name the device. Remember the Nexus S and Galaxy S series? Well, the smartphone is named Galaxy Nexus. The phone features a dual-core Texas Instruments OMAP4460 processor, a 4.65″ super AMOLED plus display (1280×720), LTE/HSPA+ network support, 1080p video recoding, NFC, barometer and more. It will be sold in the US, Europe and Asia (including Japan and China) in November. After Samsung showcased the smartphone, Google presented the new Android 4.0 (ICS). 3 Design principles: Beautiful: Enchant me Easy: Simplify my life Powerful and Smart Here are the main points I gatherer of Android 4 presentation: The new UI uses the Roboto font. They removed the physical buttons on the smartphone. Everything is now done with gestures. It looks like Honeycomb for smartphone with stacks and widgets. Widgets […]

Using Raspberry Pi as an Internet Kiosk

Following up on this morning post explaining how to get the kernel and minimal rootfs to run debian in qemu emulating an ARM1176 processor, I’ll show how to make a minimal rootfs to run Chrome browser in this platform. I tested it in QEMU, but this should also run on the Raspberry Pi hardware. First, you’ll have to complete the step I provided in Raspberry Pi Emulator in Ubuntu with Qemu. Start qemu: sudo qemu-system-arm -M versatilepb -cpu arm1176 -m 256 -hda rootfs.ext2 -kernel zImage -append “root=/dev/sda” -serial stdio Once you login to the console as root, create a new user (e.g guest): adduser guest This user will be needed to login with the graphical interface and ssh. In order to get an Internet Kiosk, we’ll need a web browser (Chromium) and a window manger. I chose fluxbox instead of gnome because of the size difference (8651 KB vs 1739 […]

Raspberry Pi Emulator in Ubuntu with Qemu

The Raspberry Pi board is a low cost board based on Broadcom BCM2835 media processor SoC with an ARM1176JZF-S core clocked at 700MHz. This board is currently under development and should be ready by end of November, beginning of December and will be sold for 25 USD (128MB RAM – no Ethernet) and 35 USD (256MB RAM – Ethernet). While we are waiting for the board, we can still test software using qemu to emulate a board based on an ARM1176 core with 128MB or 256 MB memory. I’ve tried to create a rootfs based on Ubuntu with rootstock but this only support processors with ARM cortex A8 and greater, so it would not work with ARM11. I’ll be using Debian Squeeze instead. Prerequisites My host computer is running Ubuntu 10.04.3 LTS, but any recent Ubuntu or Debian installation should work with these instructions. [Update: You won’t be able to […]

LLVM (Low Level Virtual Machine) Compiler Infrastructure

The Low Level Virtual Machine (LLVM) is a compiler and toolchain infrastructure, written in C++, designed for compile-time, link-time, run-time, and “idle-time” optimization of programs written in arbitrary programming languages. Originally implemented for C/C++, LLVM is now used with a variety programming languages such as Python, Ruby and may others. Code in the LLVM project is licensed under the “UIUC” BSD-Style license. LLVM can be used to replace and/or supplement the GNU tools such as gcc, g++, gdb, etc… LLVM now consists of a number of different sub-projects including: The LLVM Core libraries provide a source- and target-independent optimizer, along with code generation support for many popular CPUs. These libraries are built around a well specified code representation known as the LLVM intermediate representation (“LLVM IR”). The LLVM Core libraries are well documented, and it is particularly easy to invent your own language (or port an existing compiler) to use […]
