# myarm

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.
