Re: Booting NetBSD/evbarm on QEMU (IntegratorCP)

As part of a personal project to get familiar with the ARM

evaluation board.
Excellent !

And a ready to use image here:


It can be used with something like this: "qemu-system-arm -M
integratorcp -cpu arm1136 -m 128m -kernel netbsd.gz.ub -serial stdio
-net nic -net tap". This image doesn't contain a ramdisk, so you'll
need an NFS with NetBSD/evbarm root, and a properly configured DHCP
I'm trying this kernel and sadly it panics when executing init:

Make sure you have a /dev/console,  or your /dev/MAKEDEV is made with

#       NetBSD: MAKEDEV.tmpl,v 1.161 2013/01/26 18:44:21 apb Exp

or your MAKEDEV has

                    mknod -m 600 -g 0 -u 0 temp_console c 2 0
