Trouble with fonz qemu kernel.
Hi.
I trying to load fonz virtual development environment based on qemu, but it gives me errors:
qemu: hardware error: pl011_read: Bad offset 101f1018
if running with arm-start-qemu.sh
or
qemu: hardware error: integratorcm_read: Unimplemented offset 0x1f1018
if running with qemu-system-arm -kernel zImage-qemu
I have Archlinux running in VMWare with latest updates and qemu version 0.12.4, it runs fine arm testing image from qemu download page: http://wiki.qemu.org/download/arm-test-0.2.tar.gz
Any suggestions?

Re: Trouble with fonz qemu kernel.
Strange... I gave 3gb of memory to Archlinux and it uses less than 300mb (about 2.7 gb of mem. free), but if I set 256mb or less for qemu - it launches fine, if I set more than 256 - it crashes with that message.
Ok, with 256 mb it works. There must be configured and running nfs.
I had problem with nfs:
Code:
IP-Config: Complete:
device=eth0, addr=10.0.2.15, mask=255.255.255.0, gw=10.0.2.2,
host=qemu, domain=, nis-domain=(none),
bootserver=255.255.255.255, rootserver=10.0.2.2, rootpath=
Looking up port of RPC 100003/2 on 10.0.2.2
Looking up port of RPC 100005/1 on 10.0.2.2
Root-NFS: Server returned error -93 while mounting /home/ffp-0.5/arm-qemu
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "nfs" or unknown-block(2,0)
Please append a correct "root=" boot option; here are the available partitions:
0800 2049024 sda driver: sd
0810 4097024 sdb driver: sd
0b00 1048575 sr0 driver: sr
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)but it's gone after adding v3 parameter to arm-start-qemu.sh:
Code:
-append "root=/dev/nfs nfsroot=10.0.2.2:$sysroot,v3 ip=10.0.2.15::10.0.2.2:255.255.255.0:qemu:: console=ttyAMA0 rw init=/ffp/sbin/init panic=1 $extra"
