1: [[!meta title="NetBSD/evbarm under QEMU"]]
2:
3: This page attempts to document running NetBSD/evbarm under the
4: [QEMU](http://www.qemu.org/) open source processor emulator.
5: This can be extremely useful for development and testing.
6:
7: # Introduction
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).
13:
14: # Requirements
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: $ cp /usr/obj/evbearm-el/sys/arch/evbarm/compile/INTEGRATOR_CP/netbsd.gz.ub .
65: $ qemu-system-arm -M integratorcp -cpu arm1136 -m 512m -kernel netbsd.gz.ub -serial stdio -net nic -net tap,fd=3 3<>/dev/tap0
66:
67: # After booted
68: You will get the following boot messages.
