Timesys Adds Support for Freescale i.MX31 PDK 3 Stack Board
LinuxLink support for the Freescale ARM11-based i.MX31 PDK reference board has been released. The i.MX31 LinuxLink comes ready to develop with a multimedia-enhanced starting point available for the i.MX31 PDK.

The Timesys pre-assembled starting point includes the following Linux components:
Linux Kernel version 2.6.24.5 with support for the following devices:
|
 |
Toolchain
- GCC: 4.2.4
- uclibc: 0.9.29
- Binutils: 2.18.50
Enhanced for multimedia feature rich root filesystem
- Codecs
- Media players
- Web browser
- More
Access the Freescale i.MX31 LinuxLink (subscription required).

New, Enhanced for Real-Time Distribution for the MPC8641D HPCN Board (SMP)
LinuxLink for MPC8641 includes a new reference distribution — enhanced for real-time performance and optimized for the MPC8641D HPCN platform. The distribution comes with a cross-toolchain, development environment with many libraries/utilities and other ready-to-use Linux components. The starting point's Linux kernel has been properly patched and tuned to support the real-time enhancements.
Starting point details:
- Linux Kernel: 2.6.26
- Symmetric Multiprocessing (SMP)
- Platform Device drivers
- Real-Time features enabled:
- Better POSIX compliancy — Proper for real-time implementation of a number of POSIX interfaces including signals and message queues
- Fully preemptible Big Kernel Lock (BKL) — Low priority task can now hold Big Kernel Lock without adversly affecting Linux kernel latencies
- Full Real-Time Preemption — Reduces kernel latencies by minimizing non preemptible sections of the Linux kernel
- Threaded Interrupt Service Routines (ISR) — Good response time for Real-time tasks under heavy interrupt load. Interrupts compete for CPU time with user and system tasks
- High-Resolution Timers — Reduces delays for activities that need to be triggered by timeouts that are less than one jiffy
- Priority Inheritance support for kernel and user-space mutexes — Removes the problem of unbounded priority inversion for system and user tasks
- Various debugging and tracing mechanisms — Enable tracing of Linux kernel latencies during execution
- Full configurability — You can control the level of tradoff between Linux kernel latency and throughput by reconfiguring and rebuilding the kernel

New episode of LinuxLink Radio:
Interview with Mike Erickson, Marketing Product Manager with Logic
In this episode, Maciej and Gene interview Mike Erickson of Logic, a leading supplier of product-ready System on Modules (SOMs), easy to use development kits, and single board computers, and discuss weighty topics such as today's hottest processors, Linux acceptance, Pittsburgh's Mt. Washington incline, minimizing boot time, and if the consultant who claimed he was lead through a government building with a bag over his head (so as not to compromise security) was pulling Gene's leg.

Timesys Introduces Support for a New Webkit-based Web Browser
Working on a Linux project that requires Web browser capabilities? Take advantage of the webkit based Web browser optimized for embedded applications. The ready-to-use Web browser package is available via LinuxLink Factory interface, enabling you to very quickly integrate it into your project with minimal effort and resources.
WebKit is an open source application framework that provides a foundation upon which to build a web browser. WebKit was originally derived by Apple Inc. from the Konqueror browser's KHTML software library for use as the engine of Mac OS X's Safari web browser. Today it has been further developed by engineers from the KDE project, Apple, Nokia, Google, Torch Mobile and others.

Stream Audio Files Over IP Connection with LIVE555 Library
The LIVE555 is a set of libraries for multimedia streaming, using open standard protocols (RTP/RTCP, RTSP, SIP). These libraries can be used to build streaming applications. The libraries are already being used to implement applications such as "the LIVE555 Media Server" (a RTSP server application), "liveCaster" and "playRTPMPEG" (for streaming MP3 audio using RTP/RTCP). The libraries can also be used to stream, receive, and process MPEG, H.263+ or JPEG video, and several audio codecs. They can easily be extended to support additional (audio and/or video) codecs, and can also be used to build basic RTSP or SIP clients and servers.
Use LIVE555 libraries with media players like MPlayer — available today via Factory interface — to add streaming support to your multimedia based project.
