[Qemu-discuss] Problem booting arm images

[Tony Lapointe]

Hi List,

I am using qemu on gentoo, trying to boot arm based images but, i am
facing some issues.

With qemu-system-arm, i am unable to boot with a kernel that i have
compiled myself (with crossdev) but the same kernel boot just fine on a
raspberry PI board. I am also unable to boot the latest raspbian kernel
with qemu-system-arm. But, i am able to boot with a kernel found over
here :

http://xecdesign.com/qemu-emulating-raspberry-pi-the-easy-way/
http://xecdesign.com/downloads/linux-qemu/kernel-qemu

Here is the result of my tests so far.

With my own compiled kernel :

# qemu-system-arm -kernel boot/gentoo.img -cpu arm1176 -m 256 -M
versatilepb -no-reboot -serial stdio -append "root=/dev/sda5
rootfstype=ext4 rw init=/bin/bash console=ttyAMA0" -hda
img/ArchLinuxARM-2014.06-rpi.img
audio: Could not init `oss' audio driver
VNC server running on `::1:5900'


and nothing more. Even if i try with vnc qemu is telling that the guest
did dot initialized the display yet.


Same thing with raspbian kernel :

# qemu-system-arm -kernel boot/raspbian.img -cpu arm1176 -m 256 -M
versatilepb -no-reboot -serial stdio -append "root=/dev/sda5
rootfstype=ext4 rw init=/bin/bash console=ttyAMA0" -hda
img/ArchLinuxARM-2014.06-rpi.img
audio: Could not init `oss' audio driver
VNC server running on `::1:5900'


But it works with the kernel from xecdesign.com :

# qemu-system-arm -kernel boot/kernel-qemu -cpu arm1176 -m 256 -M
versatilepb -no-reboot -serial stdio -append "root=/dev/sda5
rootfstype=ext4 rw init=/bin/bash console=ttyAMA0" -hda
img/ArchLinuxARM-2014.06-rpi.img
audio: Could not init `oss' audio driver
VNC server running on `::1:5900'

Any idea, anyone?!

Thank you,
