As long as those are not graphics intensive or processor intensive, they should work just fine. You can cross-compile your application or library in your host PC (compiling them in the emulator would be very slow), copy them to the VM (via NFS for example) and run them in your ARM emulator. That’s it, you now have a running ARM virtual machine. Qemu-system-arm -m 256 -M versatilepb -kernel ~/arm-emul/vmlinuz-2.6.26-2-versatile -initrd ~/arm-emul/initrd.img-2.6.26-2-versatile -hda ~/arm-emul/hda.img -append “root=/dev/sda1” Then run Debian ARMEL in QEMU as follows: Sudo mount -o loop,offset=32256 ~/arm-emul/hda.img ~/arm-emul/mountĬp ~/arm-emul/mount/boot/initrd.img-2.6.26-2-versatile ~/arm-emul/ Once the installation is complete, mount the first disk partition of the QEMU disk image with a loop device (offset 32256) in order to copy the initrd (rootFS) ( mount QEMU images): Qemu-system-arm -m 256 -M versatilepb -kernel ~/arm-emul/vmlinuz-2.6.26-2-versatile -initrd ~/arm-emul/initrd.gz -hda ~/arm-emul/hda.img -append “root=/dev/ram”Īfter the system reboots, close QEMU. This may take several hours, since all instructions are decoded by software:
#ARM EMULATOR INSTALL#

#ARM EMULATOR HOW TO#
I’ll show how to run Debian Lenny ARMEL in QEMU on a computer running Ubuntu 10.10 (aka Ubuntu Maverick Meerkat). In a way, QEMU is similar to VirtualBox, VMWare or Citrix Xendeskop except it can support multiple architectures. This is where QEMU – a processor emulator – comes to the rescue. but you may not have the hardware required on hand to test them.
#ARM EMULATOR SOFTWARE#
However, you will have to use dpkg and apt-get to install x86 software on your guest portal.
It allows you to switch between host and guest systems by creating a guest account on your machine. The EMLINK-AH connects the JTAG interface from target board (ARM. When developing software for embedded systems, you may need to support multiple architectures such as arm, mips, x86, powerpc, alpha etc. ExaGear one of the best emulators that helps to run x86 applications on an ARM-based Raspberry Pi board.
