Building the Linux Kernel 3.0.8 For Telechips TCC8925 mini PCs (CX-01, Z900, TizzBird N1…)

Yesterday, we got Linux kernel 3.0.8 source code from Telechips, as well as some files related to Android 4.0 (Webkit + OMX). Today, I’ve had a look at the kernel source code and found a few very interesting things. First let’s get the code from github:

Good news! The code for the latest Telechips TCC892X is present in arch/arm/mach-tcc892x, and there is support for 3 types of boards: board-m805_892x – TCC8923 M805 board board-tcc8920 – TCC8920 evaluation board board-tcc8920st – TCC8920 STB evaluation board TCC8920 STB evaluation board appears to be relevant to products such as Diyomate A6, but if it’s also used for TCC8925 HDMI Dongle such as CX-01 mini PC, Zero Devices Z900 or ValuePlus TizzBird N1. Now let’s have a look at the default config directory for arm (arch/arm/configs):

Nice! tcc8925st_dongle_defconfig and tcc8925st_donglehs_defconfig look particularly interesting! A quick comparison shows that the only difference is […]

ARM TechCon 2012: Software & System Design Schedule

ARM Technology Conference (TechCon) 2012 will take place on October 30 – November 1, 2011, in Santa Clara, and UBM Electronics has already posted the detailed schedule for the event. The first day (October 30) will be Chip Designs day  and the other 2 days will focus on Software & System Design. Even if, like me, you are not be able to go there, it’s still interesting to know what will be discussed at the conference, to have a better idea where ARM is going, and what new technologies and/or development techniques are (or will become) available. There will be around 70 sessions categorized in 15 tracks: Android / Open Source –  Development tools, middleware for native application development, and optimized drivers for Android, Linux, FreeRTOS etc … Compute Platforms – Development and implementation of standards and specifications, from board/module design to consumer and server designs Developing / Debugging – […]

XBMC for Android on Mele A1000 Media Player (Video)

Following this morning announcement, I’ve started to build XBMC for Android using the instructions on XBMC Android github repository, but it takes hours on my machine. In the meantime, I’ve found a prebuilt apk that I’ve tried on my Mele A1000 and shot a (super blurry) video. This is still a development version, so there are a lot of bugs, but it shows good progress. The user interface renders at 28 fps and it’s very smooth, although CPU usage is about 65%. The remote control can work properly, but XBMC does not respond to mouse clicks and keyboard input. It can find UPNP servers (Windows) and locate your file. SMB client crashes XBMC on my system I’ve tried Big Buck Bunny 480p, 720p and 1080p, and none of the sample can play smoothly, so NEON software decoding does not appear to be fast enough to play videos smoothly. The APK […]

WiFi Tank Based on EEE PC, Arduino, Ubuntu and Node.js

Eight computer and electrical engineers built a WiFi Tank (Node.js robot) as part of a senior design project at Northeastern University, in Boston, Massachusetts. The robot brain is an EEE PC running Ubuntu, together with an Arduino board and is programmed using node.js. Each tank is equipped with a camera and 2 customized Wi-Fi repeaters (which it can drop it extend range), and it’s targeted at military operations or disaster-affected areas where network infrastructure is not available. Here are the key characteristics of this robot Robot controlled over WiFi 102 cm long, 71 cm wide, 41 cm tall, about 68 kg. Custom-built (except for treads) out of aluminum Range: 1 km with one on-board router and two droppable long-range repeater modules Running time: ~12 hours On-board webcam with microphone, night vision, pan and tilt On-board GPS for location tracking Custom-made remote user interface, works on any device with a web […]
