![]() Edit the / etc / hostsįile to avoid this error. However at this default setup virtual machine puts empty quotations as domain name which causes SampleConsoleServer to exhibit errors. You now have all the essential parts ready. jar-packages from Eclipse if you have SampleConsoleServer and SampleConsoleClient source code. This is pretty trivial, you can for example export runnable. “Normal” versions of SampleConsoleServer and SampleConsoleClient however require use of Java compiler so we have to make different packages for embedded platforms. Java SE Embedded ships without Java compiler (javac) which is understandable as embedded platforms are not intended to be used for developing applications but rather only to run them. Test that Java works by running java - versionĪcquiring SampleConsoleServer and SampleConsoleClient This can be done for example by modifying file / etc / profileĪnd adding export PATH = $PATH :/ path / to / java /./ ejre1. tar.gz folder and unzip it to desired folder. 6 uname - aĪlthough if you have followed these instructions you already have correct versions.Ĭorrect Java version for our test platform is ARMv5 Linux – Headless EABI, SoftFP ABI, Little Endian, which can be loaded from: These version numbers can be checked with: ~/ lib / libc. Java version 7 requires at least kernel version 2.6.28 and glibc version 2.9. As I am writing this from Finland my first configuration was dpkg - reconfigure keyboard - configuration Of course these passwords are recommended to be changed immediately after logging in.Īfter succesful first boot you will probably want to make some useful basic configurations. Default usernames and passwords are “root/root” and “user/user”. You should now see a virtual machine screen with Debian booting for the first time and then ending up at a login prompt. Running graphical user interface in normal QEMU setup can be really slow. If you are planning on testing only console applications, as is our case in this post, it’s recommended to use the “standard” version of the disk image. Note that 256 MiB is the maximum amount of RAM available. This option lets you increase or decrease the amount of RAM in virtual machine. Optionally you can also add “-m” option at the end of the command. 32 - 5 - versatile - hda debian_squeeze_armel_standard. Now we are ready to boot our virtual machine! Run command: sudo qemu - system - arm - M versatilepb - kernel vmlinuz - 2.6. Note that there’s also QEMU versions for Windows and Mac. We acquired these by downloading them from To start our ARM-virtual machine we need suitable kernel, initrd (initial ramdisk) and disk image. We chose Debian to be our virtual machine OS. Qemu can be installed with: apt - get install qemu - system There’s also a ARM version of Java SE, see for more details.įrom our experience until now it seems that QEMU works best with Linux platforms so we chose Ubuntu 12.04 as the host for the virtual machine. This guide is made using Java SE Embedded 7 but also other Java versions intended to be used with ARM should work. This post covers the installation and basic operation of QEMU and couple of hints to get up and running with Prosys SampleConsoleServer and SampleConsoleClient fast and easy. See or for more information about the QEMU system itself. For example, QEMU powers the Android emulator which is part of the Android SDK. QEMU emulates the ARMv5TEJ instruction set and all the derivative processors families like ARM7, ARM9E, ARM10E and XScale. It supports emulation of various architectures, including ARM. QEMU is a open-source software that performs hardware virtualization. This blog post is intended to serve as a starting point for users interested in testing Prosys Java applications on ARM platform virtual machine. From time to time we get inquiries regarding OPC UA server and client application suitability and performance on ARM platforms.
