Poky images with QEMU
|
||||
=====================
|
||||
|
||||
Poky can generate qemu bootable kernels and images with can be used
|
||||
on a desktop system. Both arm and x86 images can currently be booted.
|
||||
There are two scripts, runqemu and poky-qemu, one for use within poky,
|
||||
the other externally.
|
||||
|
||||
QEMU outside Poky (poky-qemu)
|
||||
=============================
|
||||
|
||||
The poky-qemu script is run as:
|
||||
|
||||
MACHINE=<machine> poky-qemu <zimage> <filesystem>
|
||||
|
||||
where:
|
||||
|
||||
<zimage> is the path to a kernel (e.g. zimage-qemuarm.bin)
|
||||
<filesystem> is the path to an ext2 image (e.g. filesystem-qemuarm.ext2)
|
||||
<machine> is "qemuarm" or "qemux86"
|
||||
|
||||
The MACHINE=<machine> prefix is optional and without it the script will try
|
||||
to detect the machine name from the name of the <zimage> file.
|
||||
|
||||
If <filesystem> isn't specified, nfs booting will be assumed.
|
||||
|
||||
|
||||
QEMU within Poky (runqemu)
|
||||
==========================
|
||||
|
||||
The runqemu script is run as:
|
||||
|
||||
runqemu <target> <type> <zimage> <filesystem>
|
||||
|
||||
where:
|
||||
|
||||
<target> is "qemuarm" or "qemux86"
|
||||
<type> is "ext2" or "nfs"
|
||||
<zimage> is the path to a kernel (zimage-qemuarm.bin)
|
||||
<filesystem> is the path to an ext2 image (filesystem-qemuarm.ext2)
|
||||
|
||||
It will default to the qemuarm, ext2 and the last kernel and oh-image-sdk
|
||||
image built by poky.
|
||||
|
||||
|
||||
Notes
|
||||
=====
|
||||
|
||||
- The scripts run qemu using sudo. Change perms on /dev/net/tun to
|
||||
run as non root
|
||||
- You can access the host computer at 192.168.7.1 within the image.
|
||||
- Your qemu system will be accessible as 192.16.7.2.
|
||||
- The default NFS mount points are /srv/nfs/qemux86 or /srv/nfs/qemuarm
|
||||
depending on the target type.
|
||||
- You can set QEMU_MEMORY to control amount of available memory (default 64M).
|
||||
- You can set SERIAL_LOGFILE to have the serial output from the image logged
|
||||
to a file.

||||

Known Issues
|
||||
============
|
||||
|
||||
- There is a bug in the ARM qemu in that means occasionally it will use 100%
|
||||
cpu. You will need to restart it in this situation.
|
||||
- There is a problem with the ARM image not auto assigning an IP when using an
|
||||
ext2 image. To have working TCP/IP connectivity run:
|
||||
'ifconfig eth0 192.168.7.2 up'
