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

Using qemu with poky notes
|
||||
==========================
|
||||
|
||||
Run;
|
||||
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.
|
||||
The runqemu script is run as:
|
||||
|
||||
qemu-ext2 <zimage-qemuarm>.bin <filesystem-qemuarm>.ext2
|
||||
runqemu <target> <type> <zimage> <filesystem>
|
||||
|
||||
where:
|
||||
|
||||
Via NFS
|
||||
========
|
||||
<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-pda
|
||||
image built by poky.

Move poky built qemu-system-arm into your path, i.e;

% cp ./build/tmp/staging/i686-linux/bin/qemu-system-arm /usr/local/bin

Notes
|
||||
=====
|
||||
|
||||
- The runqemu script runs qemu with sudo. Change perms on /dev/net/tun to
|
||||
run as non root
|
||||
- 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.
