Manage Rasperry Pi emulation with QEMU

Installation

Two basic ways of installation are available, in both cases make sure to use directory available via $PATH.

1. Download the script to ~/bin:

    curl -L https://raw.github.com/mpapis/myarm/master/bin/myarm -o ~/bin/myarm
    chmod +x ~/bin/myarm
   

   To update repeat the steps.

2. Clone repository and link script to ~/bin:

    mkdir -p ~/projects
    git clone https://github.com/mpapis/myarm.git ~/projects/myarm
    ln -s ~/projects/myarm/bin/myarm ~/bin/myarm
   

   To update:

    cd ~/projects/myarm
    git pull
   

The second option is useful in development when changing the script.

Usage

Prepare

Create a new virtual machine based on Rasperry Pi image:

myarm prepare [URL [name]]

• URL - url to online image from http://downloads.raspberrypi.org/images/raspbian/
• name - name of the virtual machine directory

Both can be omitted and will b auto detected, use ""(empty string) for URL if only name is important.

Start

Few ways of starting are available:

myarm start [ssh|gui|console]

• ssh - start in backgroud, wait for ssh and connect,
• gui - start in background with the GUI open to the machine,
• console - start in forground with open console to the server.
• with no parameter will just start in background, you need to wait a bit for the machine to boot, it can take even few minutes.

Stop

Stop the running virtual machine:

myarm stop

Status

Show if the virtual machine is running, returns nonzero status if it's not running:

myarm status

SSH

Allow connecting to the virtual machine:

myarm ssh

SCP

Allow upload / download of files:

myarm scp ...

Use like standard scp, use pi@localhost for the virtual machine

Configuration files

Standard virtual machine is a directory with file .myarm which contains:

IMAGE=path_to_image.img
PORT=forward_port
CPU=arm_cpu
RAM=machine_ram

Only IMAGE is required, for rest defaults will be used if not set:

PORT="5022"
CPU="arm1176"
RAM="256"

List of available CPUs can be checked with qemu-system-arm -cpu help, only arm1136-r2, arm1176, arm11mpcore were tested with myarm, other CPUs might not work.
