can u pls find the solution for this cd sudo qemu-system-arm -m 64M -nographic -M versatilepb -kernel zImage -append "console=ttyAMA0 root=/dev/nfs rw nfsroot=192.168.1.1:/home/rajesh/rootdir ip=192.168.1.101" -net nic -net tap,ifname=tap1,script=no We need to change to ~/qemu before running the scriptīut here comes new problem root=/dev/nfs doesn't exist on the installed root file system I figured out the previous problem qemu could not load kernel zImage.
QEMU SYSTEM ARM INSTALL
I will make a fresh install of Ubuntu 10.04 LTS and start going through your steps. I have tried the steps from the excercises by omitting target side instruction but it doesn't seems to work. profile in the root with cross compile option but still gives errorĬan u pls give me step by step process to build a Linux system so that I can start programming. Make: *** Error tried sh /media/cdrom/install.sh, edited. *** Can't find default configuration "arch/x86/configs/versatile_defconfig"!

QEMU SYSTEM ARM PC
NOTE: Choose a pair of address on a different sub-net to any real network the PC is attached to otherwise the IP routing is going to get mixed up. The technique used here is to create a TUN/TAP network device and connect it to the qemu process, with the host PC tap interface being 192.168.1.1 and the target address being 192.168.1.101. You need to configure a network interface so that you can communicate with the emulated target just as if it was a real board. Edit /etc/inittab and change the reference to ttyS1 to ttyAMA0.
QEMU SYSTEM ARM SERIAL
You will have to make one small change because the Digi CCW9 target board we use for training has the serial console device as ttyS1 whereas on the Versatile it is ttyAMA0. Download it, if you don't have it already, create a directory such as ~/rootdir and extract it there. Or, you can download a pre-built copy of zImage.

I have tested these instructions with qemu version 0.12.3 which comes with Ubuntu 10.04, so begin with I have chosen to use the Versatile board with an ARM926E core. For arm, we have the ARM Integrator, RealView and Versatile development boards, the Nokia N800/810 and various others. For each processor type, there are emulations of a number of hardware platforms. Each one is a separate executable: qemu-system-arm and qemu-system-mips for example. Qemu can emulate a wide range of processor types, including arm, cris, m68k, microblaze, mips, ppc and sh4. The objective, then, is to use qemu to create an arm926 environment that can run a typical embedded distribution (we use the Ångström distribution ), using an NFS root mount to a file system on the host PC. Thinking about it a bit more, I realise that the situation is general and common enough to be useful to many people (or so I hope) and so I have written this tutorial. I said, you could use qemu to emulate an ARM target that is rather similar to the one we actually use.
QEMU SYSTEM ARM HOW TO
At the end of one of my training courses recently we got into a discussion about how to continue working with the code and configurations developed during the course after everybody had gone home and they no longer had a target board.
