1.1 riz 1: [[!meta title="NetBSD/evbarm under QEMU"]]
2:
1.3 ryoon 3: This page attempts to document running NetBSD/evbarm under the
4: [QEMU](http://wiki.qemu.org/Main_Page) open source processor emulator.
5: This can be extremely useful for development and testing.
1.1 riz 6:
7: # Introduction
1.4 ! ryoon 8: QEMU emulates ARM's Integrator/CP board. You can run NetBSD under it.
! 9: Older NetBSD had the problem to run under QEMU's emulated Integrator/CP
! 10: board.
! 11: Sergio López had created the patch for NetBSD current and had posted
! 12: to port-arm mailing list in [6 Febrary, 2013](http://mail-index.NetBSD.org/port-arm/2013/02/06/msg001739.html).
1.1 riz 13:
14: # Requirements
1.4 ! ryoon 15: * pkgsrc/emulators/qemu 1.6.2 and 1.7.0
! 16: * INTEGRATOR_CP kernel of NetBSD/evbearm 6.99.28 or later
! 17: (some provious versions should work, but not tested)
! 18:
! 19: ## Preparing QEMU
! 20: You can install latest qemu with the following commands.
! 21: It is assumed that your pkgsrc tree is in /usr/pkgsrc directory.
! 22:
! 23: # cd /usr/pkgsrc/emulators/qemu
! 24: # make install
! 25:
! 26: ## Preparing NetBSD userland and kernel
! 27: You can create INTEGRATOR_CP kernel, and kernel/userland tarball with
! 28: the following commands.
! 29: It is assumed that your NetBSD src tree is in /usr/src directory.
! 30:
! 31: $ cd /usr/src
! 32: $ ./build.sh -U -T /usr/tools/evbearm-el -O /usr/obj/evbearm-el \
! 33: -D /usr/NewWorld/evbearm-el -R /usr/release/evbearm-el \
! 34: -m evbearm release
! 35: $ ./build.sh -U -T /usr/tools/evbearm-el -O /usr/obj/evbearm-el \
! 36: -D /usr/NewWorld/evbearm-el -R /usr/release/evbearm-el \
! 37: -m evbearm kernel=INTEGRATOR_CP
! 38:
! 39: # Booting
! 40: INTEGRATOR_CP kernel has no disk drive support.
! 41: You should setup netboot environment.
! 42:
! 43: ## Setting up netboot environment
! 44: You can use existing NetBSD or other Unix like operating system environment
! 45: for host netboot.
! 46: You can also utilize qemu-system-amd64 or qemu-system-i386 to host
! 47: netboot.
! 48:
! 49: tftp is not needed, kernel is specified in commandline of qemu-system-arm.
! 50: Only NFS root is needed.
! 51: In detail see [Diskless NetBSD howto's Setting up the NFS server section](http://www.netbsd.org/docs/network/netboot/nfs.html).
! 52:
! 53:
! 54: # Booting INTEGRATOR_CP kernel
! 55: You can boot INTEGRATOR_CP kernel with the following commandline.
! 56: It is assumed that the host machine uses bge0 to connect to your network.
! 57:
! 58: # ifconfig bridge0 create
! 59: # brconfig bridge0 add bge0
! 60: # ifconfig bridge0 up
! 61: # ifconfig tap0 create
! 62: # ifconfig tap0 0.0.0.0 up
! 63: # brconfig bridge0 add tap0
! 64: $ qemu-system-arm -M integratorcp -cpu arm1136 -m 512m -kernel netbsd.gz.ub -serial stdio -net nic -net tap,fd=3 3<>/dev/tap0
! 65:
! 66: # After booted
! 67: You will get the following boot messages.
