Start an arm Virtual Machine

$ arm_now start armv5-eabi
Welcome to arm_now
buildroot login: root
# uname -m
armv7l

Resizing an arm Virtual Machine

$ 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

$ arm_now start mips32el
Welcome to arm_now
buildroot login: root
# gdb /bin/ls
(gdb) start
