Well, you don't have enough money to buy an Armadeus board and just want to be part of the "Software" side of the project ? Then QEMU can be a good choice for you !!
Just be aware that currently Armadeus hardware is not emulated under QEMU, we are just using an other board hard and linux kernel to launch our Rootfs an test our software which is not custom hardware related (ie User interface, Network, etc...)
Installation
- on Debian just do a:
[armadeus]$ sudo apt-get install qemu
Get/generate simulation images
- In our tests we used the QEMU Versatile PB emulated hardware. To get a compatible Linux kernel for this board then:
[armadeus]$ wget http://people.debian.org/~aurel32/arm-versatile/vmlinuz-2.6.18-5-versatile
- Generate your Armadeus Rootfs as an EXT2 image, and zip it (we will use it as Ramdisk first):
[armadeus]$ gzip -9 buildroot/rootfs.arm_nofpu.ext2
- Create a fake QEMU Hard disk image
[armadeus]$ qemu-img create -f qcow qemu.img 10M
Launch it
- At first boot, you have to launch the system as a Ramdisk:
[armadeus]$ qemu-system-arm -m 32 -M versatilepb -kernel vmlinuz-2.6.18-5-versatile \
-initrd rootfs.arm_nofpu.ext2.gz -append "root=/dev/ram" -hda ./rootfs.arm_nofpu2.img
- When system has booted, we will create the "hard disk" image:
# mkdir /tmp/dev # mknod /tmp/dev/sda b 8 0 # mknod /tmp/dev/sda b 8 1 # fdisk /tmp/dev/sda n p 1 <enter> <enter> # mkfs.ext2 /tmp/dev/sda1
