Cross-comping zlib for ARM target

Zlib is defind as “A Massively Spiffy Yet Delicately Unobtrusive Compression Library” and used in many projects requiring compression. Here are the instructions cross-compile zlib for ARM: Download zlib1.25 wget http://cdnetworks-kr-2.dl.sourceforge.net/project/libpng/zlib/1.2.5/zlib-1.2.5.tar.gz Extract it tar xzvf zlib-1.2.5.tar.gz cd zlib-1.2.5 Configure, build and install zlib. CC=armv5tel-redhat-linux-gnueabi-gcc ./configure –prefix=/home/jaufranc/edev/rootfs make make install This will install libz.a (static library) and libz.so (dynamic library) in /home/jaufranc/edev/rootfs/lib and copy the header files to /home/jaufranc/edev/rootfs/include.

Installing an ARM Toolchain in Fedora

You can easily install an arm cross-compiler on Fedora as follows: cd /etc/yum.repos.d/ sudo wget http://ftp.linux.org.uk/pub/linux/arm/fedora/cross/cross.repo sudo yum install armv5tel-redhat-linux-gnueabi-gcc You can check the installation worked by checking the cross-compiler version [jaufranc@localhost ~]$ armv5tel-redhat-linux-gnueabi-gcc -v Using built-in specs. Target: armv5tel-redhat-linux-gnueabi Configured with: ../configure –prefix=/usr –mandir=/usr/share/man –infodir=/usr/share/info –enable-shared –enable-threads=posix –enable-checking=release –with-system-zlib –enable-__cxa_atexit –disable-libunwind-exceptions –enable-languages=c,c++ –disable-libgcj –with-sysroot=yes –enable-version-specific-runtime-libs –target=armv5tel-redhat-linux-gnueabi Thread model: posix gcc version 4.1.2 20070925 (Red Hat 4.1.2-33.fa1) This will only install the C compiler (gcc), to install the C++ compiler, run the following command: sudo yum install armv5tel-redhat-linux-gnueabi-gcc-c++ Tested in Fedora 12.

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 […]
