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.


$ sudo pip3 install
$ sudo pip3 install arm_now # this is not recommended yet

Actually, arm_now doesn't require any root privilege, you can install it as a normal user if you want as long as arm_now is in your $PATH...

Start an arm Virtual Machine

$ arm_now start armv5-eabi
Welcome to arm_now
buildroot login: root
# uname -m

Debug ls binary on mips

$ 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 <main+12>:	li	a0,-1

  list          List all available images for all cpu.
  start         Start a vm with a <arch> cpu. (default: armv5-eabi)
