Virtual Hardware Platforms: Test & Debug Software Before the Silicon is Ready

Historically software could only be tested and debugged when the first silicon sample was ready, and the software team could not participate in the design process. But thanks to Virtual Hardware Platforms, software can be executed at speeds close to real time on an abstract model of the hardware, available long before a design has been completed. The virtual platform is designed to simplify the creation and support of virtual prototypes and allow design teams to begin developing software weeks to months before a hardware prototype is available, and software teams can use it as their application development platform. For example, Freescale is using a Virtual Hardware Platform for their new Vybrid Controllers to emulate both Cortex A5 and Cortex M4 cores, as well as peripherals and run OS such as Linux or MQX before the Controllers are ready (Q2 2012). One Virtual Hardware Platform has just won the ACE […]

Glark, an alternative to Grep

grep is a very useful tool to search or filter strings in order to look for files, parse useful info in log files and more. glark is an alternative to grep, it has few features that grep does not such as complex expressions, Perl-compatible regular expressions, and excluding binary files. It also has a more fancy way of display results. It is described as follows in the manpage: Similar to “grep”, “glark” offers: Perl-compatible regular expressions, color highlighting of matches, context around matches, complex expressions (“and” and “or”), grep output emulation, and automatic exclusion of non-text files. Its regular expressions should be familiar to persons experienced in Perl, Python, or Ruby. File may also be a list of files in the form of a path. glark is not installed by default. To install it in Debian/Ubuntu/Mint: sudo apt-get install glark It does not appear to be available in Fedora and […]

98 Raspberry Pi Boards Left for Qt Developers

In November 2011, the Raspberry Pi foundation announced that Nokia purchased codes for 400 boards from the 1st 10,000 batch, in order to give them away to selected developers that are interested in helping develop and test Qt 5 on the Raspberry Pi. This developer program is called QtonPi. The surprising part if that they struggle to distribute all those boards. Although to date 425 people have been selected, only 302 are currently eligible to receive a board because over 100 developers did not provide their details to receive the free Raspberry Pi board namely: Their full name The link to their wiki user profile. The area of the “QtonPi Accepted Page” where they are listed. The country where the board will be shipped If by chance, you are reading this blog, have been selected but you can’t see “OK” or “CODE SENT” next to your user ID, you should […]

ADB: (Android Debug Bridge) : How It Works – Android Builder Summit 2012

Tetsuyuki Kobayashi, working at Kyoto Microcomputer a Japanese development tool vendor, explains how the ADB (Android Debug Bridge) works at Android Builder Summit in February 2012. Abstract: ADB is very nice and important tool. Every Android Builders uses adb command such as ‘adb shell’ and ‘adb logcat’. But what does it mean ‘adb kill-server’ ? I studied the source code of adb. I share you how adb works and some tips I found. This session is for developers who want to know Android internal deeply. You can also download the presentation slides on linuxfoundation.org website.

Cross-compiling FreeRDP Windows Remote Desktop Client for ARM Linux (in Debian/Ubuntu)

Last month, I wrote the instructions to Cross-compile VMWare View for ARM Linux as I intended to “run” Windows 8 in an ARM client (most likely the Raspberry Pi) via PCoIP. However, the procedure to do so seems slightly complicated and requires to purchase a specific VMWare server software (VMware vSphere 5) or download a free trial. The good news is that there are other options such as VNC or RDP (Remote Desktop protocol) and Remmina, a Remote Connection client is available for Linux. As nothing is ever simple, another issue occured: if you are using a stable release of Linux (e.g. Debian Squeeze, Ubuntu 11.10) they come with older version of Remmina and either the connection is successful but the display is garbled (Version 0.7.x) either it crashes when connecting to Windows 8 via RDP (Version 0.8.x). The latest version (Remmina 1.0.0) fixes the problem and is available in […]

How to build qemu-system-arm in Linux

Most (all?) Linux distributions have a binary package for qemu-system (including qemu-system-arm) in order to emulate non-x86 targets such as ARM, MIPS, PPC, Alpha and more. However, in some case you may need to very latest version of qemu-system and it may not be able yet for your distribution. Here’s how to do to build qemu-system-arm without building all qemu-system-***: Download the latest stable version of qemu (qemu 1.0.1 at the time this post was written):

wget http://wiki.qemu.org/download/qemu-1.0.1.tar.gz

1	wget http://wiki.qemu.org/download/qemu-1.0.1.tar.gz

or get the latest source code (development tree) which has the very latest features and bug fixes, but may not work or compile:

git clone git://git.qemu.org/qemu.git

1	git clone git://git.qemu.org/qemu.git

or get the latest source code from linaro (which may be more up-to-date for ARM targets):

git clone git://git.linaro.org/qemu/qemu-linaro.git

1	git clone git://git.linaro.org/qemu/qemu-linaro.git

Configure qemu to build ARM targets:

cd qemu
./configure --target-list=arm-softmmu,arm-linux-user

1 2	cd qemu ./configure --target-list=arm-softmmu,arm-linux-user

Build and install qemu-system-arm:

make -j 2
sudo make install

1 2	make -j 2 sudo make install

Verify the latest version of qemu-ssytem-arm is installed:

# qemu-system-arm --version
QEMU emulator version 1.0,1, Copyright (c) 2003-2008 Fabrice Bellard

1 2	# qemu-system-arm --version QEMU emulator version 1.0,1, Copyright (c) 2003-2008 Fabrice Bellard

LAVA Project Update – ELC 2012

Paul Larson of Linaro gives a LAVA Project update at Embedded Linux Conference 2012. Abstract: The Linaro Automated Validation Architecture (LAVA) is an open source framework used at Linaro for running automated tests on Ubuntu and Android based images, kernels, and more. I introduced LAVA at ELC a year ago. Since that time, considerable progress has been made on the project, and many new components have been added to it. This talk will briefly re-introduce the project to those who may not have heard about it, as well as introduce the new developments. You can download the presentation slides at elinux.org.
