qemu-arm poky image notes
=========================
Poky can generate qemu-system-arm bootable kernels and images with can
then be used on an x86 desktop. There are two ways to run such images;
Via ext2 filesystem image
==========================
Run;
qemu-ext2 <zimage-qemuarm>.bin <filesystem-qemuarm>.ext2
Via NFS
========
As root;
% apt-get install nfs-kernel-server
% mkdir /srv/qemuarm
Edit via /etc/exports :
# /etc/exports: the access control list for filesystems which may be exported
# to NFS clients. See exports(5).
/srv/qemuarm 192.168.7.2(rw,no_root_squash)
% /etc/init.d/nfs-kernel-server restart
% modprobe tun
untar build/tmp/deploy/images/<built image>.rootfs.tar.bz2 into /srv/qemuarm
Move poky built qemu-system-arm into your path, i.e;
% cp ./build/tmp/staging/i686-linux/bin/qemu-system-arm /usr/local/bin
Finally, launch:
% ./qemu-nfs ../../build/tmp/deploy/images/<zimage-qemuarm>.bin
( change perms on /dev/net/tun to run as non root )
Notes
=====
- You can set QEMU_MEMORY env var to control amount of available memory
( defaults to 64M )
- There is a bug in qemu in that means occasionally it will use 100% cpu.
You will need to restart it in this situation.
