qemuarm hangs

qemuarm hangs

[Gary Thomas]

Building from master, updated earlier today.

OE Build Configuration:
BB_VERSION        = "1.11.0"
METADATA_BRANCH   = "my_master"
METADATA_REVISION = "2e4518bf18d977e1249ef7e7cd384df66e7b4801"
TARGET_ARCH       = "arm"
TARGET_OS         = "linux-gnueabi"
MACHINE           = "qemuarm"
DISTRO            = "poky"
DISTRO_VERSION    = "1.0+snapshot-20110511"
TARGET_FPU        = "soft"

When I runqemu on core-image-sato, it brings up the simulated
video screen and the Yocto splash shows.  The progress bar goes
to about 60% and then it just hangs there forever.

core-image-minimal boots to a login prompt

Ideas?  How can I figure out where it's bombing out?

When I saw this go by:

    qemu: Upgrade qemu git to the latest 0.14 branch

    Also add missing patch to build qemu-git

    [YOCTO #1013] got fixed

    (From OE-Core rev: 9b80846152931bed018f33baaaf1ba253e756867)

I wondered about compatibility. Have you tried with the older qemu ?

I believe so.  I ran the same test a few days ago and it worked fine.
I'm trying qemux86 now with this latest tree.  After that, I could
try reverting the change you mention.

Any clues how to get "under the covers" when booting a qemu image?
Once it brings up the video/splash screen, I'm in the dark as to
what's going on.

Typically I'd redirect the console to another tty, but you
could use SERIAL_LOGFILE as an option to your qemu launch
to log the tty output to something you can watch while the
splash screen takes over. But I must warn, that I've never
actually used that option with poky :)

Alternately, removing psplash (or disabling it) in your
sato rootfs would get you more information, and let you
know if it is just the graphics causing a problem.

Several ways:

a) You can redirect the console as Bruce mentions

b) there is an option you can add to the kernel commandline to disable
psplash (psplash=false)

c) you can switch the console as you normally would under Linux which
triggers psplash to terminate (Something like Crtl+Alt+F2 then Ctrl+Alt
+F1 again but I can't remember the exact combination off the top of my
head)

Disabling the psplash screen, I see this error:
   Running postinst /etc/rpm-postinsts/gthumb.sh
   Failed to load file "/etc/gconf/gconf.xml.defaults/%gconf-tree-pl.xml": Error on line 363 char 9: Element 'dir' was closed, no element is currently open
I think this was a result of an incomplete [previous] startup, so I
tried with a fresh image.  This time, it made it all the way to X,
so I guess I was just too impatient (of course, it took almost 8 minutes
to get to X on a 2.4GHz Core-2 Duo!)

I'll continue with my experiment to see how this runs on qemux86

Sorry for the noise.  I do think a slight improvement in the runqemu
script can help with situations like this.  I had to edit the scripts
to add the 'psplash=false' kernel option.  With the attached patch,
you can do it directly:
   % SCRIPT_KERNEL_OPT='psplash=false ' runqemu qemuarm

Note that this is the git recipe, not the released version. I've just
realised that it should have a DEFAULT_PREFERENCE = "-1" and doesn't
though. These git versions used to be great for testing upstream changes
before they hit releases but they shouldn't be the default and I suspect
this on has slipped to become default due to the PV change.

It is of course a worry if the upstream version is broken but that is a
different problem :/.
