问题
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:
- I am new to Beagleboard and Qemu environment.
- 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.
