[yocto] Arago project image fail to run in QEMU

[Sudhangathan B S]

These simple steps should do..

change your local.conf file to appear like this:

#
# Machine Selection
#
# You need to select a specific machine to target the build with. There are
a selection
# of emulated machines available which can boot and run in the QEMU
emulator:
#
MACHINE ?= "qemuarm"                                         <---- note this
#MACHINE ?= "qemumips"
#MACHINE ?= "qemuppc"
#MACHINE ?= "qemux86"
#MACHINE ?= "qemux86-64"
#
# There are also the following hardware board target machines included for
# demonstration purposes:
#
#MACHINE ?= "atom-pc"
#MACHINE ?= "beagleboard"
#MACHINE ?= "mpc8315e-rdb"
#MACHINE ?= "routerstationpro"
#
# This sets the default machine to be qemux86 if no other machine is
selected:
#MACHINE ??= "qemux86"

now run (internet/downloading is necessary):
"bitbake <keystone-II image>"
you can find the built images in deploy/images folder, which you don't need
to
access, then to start the virtual machine, just type (from the same path as
bitbake):
"runqemu qemuarm"
Type *your user password when asked for. Done.

Best,
