Set up Beagleboard emulator with qemu in Ubuntu

Question

To setup qemu for Beagleboard in Ubuntu 14.04, I am following steps given in link below:

http://www.cnx-software.com/2011/09/26/beagleboard-emulator-in-ubuntu-with-qemu/

When I tried to run ALIP image in qemu by command :

sudo qemu-system-arm -M beagle -m 256 -drive file=./beagle_sd_alip_x11.img,if=sd,cache=writeback -clock unix -serial stdio -device usb-kbd -device usb-mouse

I got following error :

qemu-system-arm: -M beagle: Unsupported machine type
Use -machine help to list supported machines!

How can I fix this error ?

PS:

1. I am new to Beagleboard and Qemu environment.
2. I am trying to understand Userspace Arduino Libraries for Beagleboard.More details about it can be found here: http://elinux.org/Userspace_Arduino .It would be great if anyone can guide to test example codes like blinking led, 7 segment display etc.from Userspace Arduino in Qemu.

You can build qemu with beagleboard support yourself with these steps, which I have tried with Ubuntu 14.04.

First remove the qemu package that you have installed with

$ sudo apt-get remove qemu-system-arm

Then download the source code for qemu to a suitable folder

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

You need these two packages to build qemu

$ sudo apt-get install libglib2.0-dev zlib1g-dev

You will also need the pixman and dtc git submodules

$ git submodule update --init pixman $ git submodule update --init dtc

Now you can continue and configure and build it!

$ mkdir build $ cd build $ ../configure --prefix=/opt $ make -j8 $ sudo make install

The qemu-system-arm executable can be found in /opt/bin. Add this to your path if you haven't already and you´re good to go.
