qemu-rpi-archlinuxarm

ArchlinuxARM emulator using QEMU Easy setup script.

I made this script after messing around quite a bit on how to get the qemu working for rpi emulation of the latest archlinuxarm.

goals of this script is to be able to:

git clone https://github.com/dotrar/qemu-rpi-archlinuxarm
cd qemu-rpi-archlinuxarm
./setup
./run

the setup file will install a desktop file, you can specify -d to output to console, thereby avoiding the desktop file install

Important Read the Known Issues section

Current work arounds;

After ./run you must switch to serial0 to log in via root; that's as far as i got.

If anyone wants to help put networking in the run script; then we'd be golden.

Manual process

The start command I use to start-up archlinux arm is: (note, some filenames differ)

#:: startup
qemu-system-arm \
 -kernel ./boot/kernel7.img \
 -cpu arm1176 \
 -M raspi2 \
 -dtb ./boot/bcm2709-rpi-2-b.dtb\
 -sd fs.img \
 -initrd ./boot/initramfs-linux.img\
 -append "root=/dev/mmcblk0p1 rw rootwait console=ttyAMA0,9600 console=tty1 selinux=0 plymouth.enable=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 elevator=noop"

This process includes no seperate boot partition, If you want a seperate boot, you must change root=/dev/mccblk0p2 or where-ever your root partition now is.

the fs.img is a qemu-qcow2 image but might also work with raw images. Built the fs.img to be 8GB, format with mkfs.ext4 then mounted with qemu-nbd

Copied the files from wget http://os.archlinuxarm.org/os/ArchLinuxARM-rpi-2-latest.tar.gz

bsdtar -xpf ArchLinuxARM-rpi-2-latest.tar.gz -C fs.mountpoint

copy the kernel, dtb, and the initramfs out.

Known issues

Still submit patches to get the issues resolved

Serial causes kernel panics, but can be the only way to get log-in, drivers crash but kernel keeps chugging.
No Network yet.
