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.

Cross-compiling VMWare View for ARM Linux (in Debian/Ubuntu)

Earlier this month, I wrote an article about PCoIP Technology which shows an Android application (VMWare View) running on an OMAP4 Tablet displaying a Windows 7 desktop. This remote desktop technology relies on a powerful server to do the processing and thin clients (in that case Tablets) to display the desktop. Since only pixels are transferred any OS (supported by the server) could be displayed in the thin client. That made me wonder if there was an open source PCoIP client that could run on low end Linux client such as the Raspberry Pi. VMWare View Open Client provides just what we need, but is only available in source code so we need to cross-compile it for ARM or build it in an ARM machine. Today, I’ll show the instructions I followed to cross-compile it for ARM in Debian using Emdebian Toolchain. First download and extract VMware View Open Client […]
