Introduction------------
This configuration offers a cross-build of (a subset of) the build-bootstrappackage selection for the arm architecture as emulated by qemu-system-arm.It includes support for all the hardware emulated by qemu, a working udev,kernel and userland support for TCP/IP networking, and more.
With qemu and the resulting build you can at least:- boot the kernel and first stage initrd,- execute a shell from the initrd,- load the second stage from a CD-ROM,- and install packages from the CD on a hard disk.
The packages included should be sufficient for native builds on the targetedplatform.
Quick Start-----------
Direct booting with framebuffer console:qemu-system-arm -kernel build/bbs-arm-qemu-TRUNK-arm-EL-arm926ejs-cross-generic-expert/boot/zImage \ -initrd build/bbs-arm-qemu-TRUNK-arm-EL-arm926ejs-cross-generic-expert/ROCK/target/initrd.img \ -append "root=/dev/ram0 rw" -M versatilepb \ -cdrom bbs-arm-qemu_cd1.iso -hda /srv/qemu.hda
Direct booting with serial console:qemu-system-arm -kernel build/bbs-arm-qemu-TRUNK-arm-EL-arm926ejs-cross-generic-expert/boot/zImage \ -initrd build/bbs-arm-qemu-TRUNK-arm-EL-arm926ejs-cross-generic-expert/ROCK/target/initrd.img \ -append "root=/dev/ram0 console=ttyAMA0 rw" -nographic -M versatilepb \ -cdrom bbs-arm-qemu_cd1.iso -hda /srv/qemu.hda
Hints And Known Bugs--------------------
- To use the cdrom image in qemu, create it after the build has finished: ./scripts/Create-ISO bbs-arm-qemu bbs-arm-qemu
- To use a hard disk in qemu, create it with e.g.: qemu-img create /srv/qemu.hda 2048M
- When using a console on the serial port, be sure to enter 'ttyAMA0' as the terminal device in boot stage 2, or you won't get to see the command line.
- This build also works with '-M versatileab', for other machine types you only have to rebuild the kernel.
- For an unknown reason, find is broken in this build (but works in e.g. sparc and x86_64 cross-builds). Use oldfind instead.
- Package installation with stone does not work yet; use mine directly to install packages.
