AMD G-Series QSeven Module Conga-QAF by Congatec

Congatec announced the Conga-QAF, a Qseven module powered by AMD G-Series embedded processors. The module will come with either the AMD G-T40R single core or the AMD G-T40E dual core processor, with 2 GB DRAM by default (expandable to 4GB), numerous I/O interfaces and an optional on-board SSD with a capacity of up to 32 GB. If you are not familiar with the QSeven Form Factor and why it is used, please read the beginning of the blog post entitled “QSeven Form Factor Embedded Boards by Seco“. To summarize, this is a standard to allow developers to use modules (based on QSeven specs) to test their software on several processors by inserting those modules in a common main board. Here are the specification of the Conga-QAF Qseven module: CPU AMD G-T40E 1.0 GHz Dual Core (L1 cache 64KB, L2 cache 512kB x2, 6.4 W) AMD G-T40R 1.0 GHz Single Core […]

NFC Smart Meter Demo by NXP and Landis-Gyr

NXP and Landis+Gyr are showcasing smart meters equipped with NFC technology at the Metering Europe 2011 event in Amsterdam this week. The companies are demonstrating how utility companies will be able to use NFC smart meters to: Save money by removing the need to include an LCD display in a smart meter. Meter readers will instead use an NFC-enabled phone to take a reading from the meter and then use their handset to collect and view current and historical energy consumption. Use an embedded secure element in the smart meter to increase customer privacy while at the same time providing the necessary level of access to installation and service technicians. Enable authorised maintenance technicians to download metering information to handsets or tablets as well as upload firmware updates to the meter via NFC. Use secure device pairing to deliver home area network (HAN) capabilities. Provide secure and convenient pre-payment of […]

Xibo Digital Signage on ARM (Beagleboard / Overo)

Xibo (pronounced eX-E-bO) is an open source, multi-display, multi-zone, fully scheduled digital signage solution written in Python (there is also a dotnet version). This is a client /server solution that can run on Windows or Linux. If you are not familiar with Xibo you can visit http://xibo.org.uk/ or/and read my introduction XIBO: An Open Source Digital Signage Server/Client. Since I had not seen digital signage solution running on low cost ARM development platform such as Beagleboard, Pandaboard or Origen, I decided to give the Xibo python client a try using qemu to emulate Gumstix Overo COM (OMAP 3530). Porting Xibo to ARM could provide several benefits compared to x86 platform: Lower hardware cost Lower power consumption (and electricity bill) Smaller form factor allowing easier integration in displays and in transportation (e.g. buses, subway trains). Easier to implement new digital signage features such as touch screen support, 3G connectivity, location based […]

Cross Compiling libavg for ARM

libavg is a high-level development platform for media-centric applications using Python as scripting language and written in C++. Bear in mind that are many dependencies with libavg 1.6. I have not built all the libraries required, but instead simply taken the pre-built binaries and header files in the qemu overo image and copied the files as follows: mkdir mnt sudo mount -o loop,offset=$[106496*512] overo_sd_alip.img mnt mkdir ~/edev/beagleboard/libs/lib -p mkdir ~/edev/beagleboard/libs/include cp mnt/usr/lib/* ~/edev/beagleboard/libs/lib/ -rf -d cp mnt/lib/* ~/edev/beagleboard/libs/lib/ -rf -d cp /mnt/usr/include/* ~/edev/beagleboard/libs/include -rf -d sudo umount mnt The -d flag skips the symlink, so we need to recreate then for all library so that the compiler can find libname.so instead of libname.so.12. Save the following scripts to symlinks.sh:

#!/bin/sh
liblist=`ls *.so.??`
for f in $liblist
do
  echo $f
  fileres=`echo $f | sed 's/\..\{2\}$//'`
  ln -s $f $fileres
done
liblist=`ls *.so.?`
for f in $liblist
do
  echo $f
  fileres=`echo $f | sed 's/\..\{1\}$//'`
  ln -s $f $fileres
done

#!/bin/sh

liblist=`ls *.so.??`

for f in $liblist

echo $f

fileres=`echo $f | sed 's/\..\{2\}$//'`

ln -s $f $fileres

done

liblist=`ls *.so.?`

for f in $liblist

echo $f

fileres=`echo $f | sed 's/\..\{1\}$//'`

ln -s $f $fileres

done

and run it where the arm libraries are located (in my case in /home/jaufranc/edev/beagleboard/libs/lib, /home/jaufranc/edev/beagleboard/libs/lib/arm-linux-gnueabi and /home/jaufranc/edev/beagleboard/libs/lib/mesa). This will create symlinks for most libraries, but not all. Some will still […]
