# arm_now 1.2
arm_now is a qemu powered tool that allows instant setup of virtual machines on arm cpu, mips, powerpc, nios2, x86 and more, for reverse, exploit, fuzzing and programming purpose.
# Install
```sh
# pip3 install https://github.com/nongiach/arm_now/archive/master.zip --upgrade
# # Or you can also do:
# pip3 install arm_now
```
Supported System: Linux, Windows WSL, MacOS, Docker.
# Docker install
If you are using docker, just run and enjoy!
```sh
$ docker run -it --name arm_now -v $PWD:/mount --rm bannsec/arm_now_docker arm_now
```
For a bash function wrapper see here: https://github.com/bannsec/arm_now_docker
# Start an arm Virtual Machine
```sh
$ arm_now start armv5-eabi
Welcome to arm_now
buildroot login: root
# uname -m
armv7l
```
# Resizing an arm Virtual Machine
```sh
$ arm_now resize +10G
WARNING: Image format was not specified for 'arm_now/rootfs.ext2' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.
Image resized.
```
# Debug the ls binary on mips
```sh
$ arm_now start mips32el
Welcome to arm_now
buildroot login: root
# gdb /bin/ls
(gdb) start
Temporary breakpoint 1, 0x00405434 in main ()
(gdb) x/i $pc
=> 0x405434 : li a0,-1
```
## How to exit qemu
