no, this is the wrong init ramdisk.
<div>Here is what i did:<br>
<div>First install the ubuntu core on a SD card (without init
ramdisk), then boot the pandaboard and install the TI PPA.
After updating the bootloader (with "flash-kernel
--update-bootloader"), the init ramdisk is being generated in
the boot partition. Then, change the /boot/boot.script to load
the uInitrd and update the bootloader again ("flash-kernel").
Reboot and everything will work.<br>

On first boot there now seems to be a net installation that
wants to format the rootfs and create a user, etc. This
seems to no longer be "Ubuntu core" and destroys the tarball

Apparently you are facing uInitrd issue.<br>
We realized very recently that without the uInitrd,

You just need to update your boot.scr/boot.script

I followed these instructions to create an

I am still not sure why you are using
omapdss.def_disp=dvi
<blockquote type="cite">The instructions say to
use "vram=32M" but I know that is no longer
valid, so I took that out. Also, both the DVI

after doing that the HDMI port was activated,
not the DVI one. Strange...<br>

With the TI PPA kernel, HDMI and DVI shall be
auto-detected at boot and you shall be able to
use both connector.<br>
<blockquote type="cite">C.) Before doing the
"apt-get install xorg", I did "apt-get install

omapdrm_prv will be triggered only after X
startup in fact.<br>
<blockquote type="cite">D.) After doing the
"apt-get install xorg" I stopped with the
instructions, since I don't want a window
manager. I'm trying to make an image as
minimal as possible.<br>
<br>
To answer your questions (with my Pandaboard
in the state described above):<br>
1.) So you are using TI PPA, correct?<br>
<br>
Yes. In /etc/apt/sources.list:<br>
# TI release PPA<br>
deb <a moz-do-not-send="true"
href="http://ppa.launchpad.net/tiomap-dev/release/ubuntu"
target="_blank">http://ppa.launchpad.net/<wbr>tiomap-dev/release/ubuntu</a>
precise main <br>
deb-src <a moz-do-not-send="true"
href="http://ppa.launchpad.net/tiomap-dev/release/ubuntu"
target="_blank">http://ppa.launchpad.net/<wbr>tiomap-dev/release/ubuntu</a>
precise main<br>
<br>
2.) Can you ensure that you perform
dist-upgrade? We indeed have renamed some
packages so aptitude needs that you perform
dist-upgrade to replace existing package with
new ones.<br>
<br>
Apparently I already have the latest:<br>
root@localhost:~# apt-get dist-upgrade<br>
Reading package lists... Done<br>
Building dependency tree      <br>
Reading state information... Done<br>
Calculating upgrade... Done<br>
0 upgraded, 0 newly installed, 0 to remove and
0 not upgraded.<br>
<br>
3.) Can you check if pvr module is correctly
installed?<br>
After the boot perform: lsmod | grep
omapdrm_prv<br>
If this module is not loaded you might need to
execute:<br>
sudo apt-get install --reinstall
pvr-omap4-dkms<br>
<br>
Even though I did "apt-get install --reinstall
pvr-omap4-dkms" previously, I still don't see
"omapdrm_prv" now on reboot. I installed it
again just now and rebooted - it did not show
under lsmod until after I ran "startx".Â
Apparently I will always need to startx first.<br>
</blockquote>
Yes, omapdrm_prv is automatically loaded only
after you startx, this is expected.<br>
<blockquote type="cite"><br>
4.) Can you ensure that you are running the
last kernel? Please send "uname -a" output.<br>
<br>
root@localhost:~# uname -a<br>
Linux localhost.localdomain 3.4.0-1487-omap4
#6-Ubuntu SMP PREEMPT Mon Oct 1 16:54:59 UTC
2012 armv7l armv7l armv7l GNU/Linux<br>
</blockquote>
OK.<br>
<blockquote type="cite"><br>
5.) Why are you using omapdss.def_disp=dvi in
your bootargs?<br>
<br>
I saw this on <a moz-do-not-send="true"
href="http://omappedia.org/wiki/Bootargs_for_enabling_display"
target="_blank">http://omappedia.org/wiki/<wbr>Bootargs_for_enabling_display</a>
and added it since neither HDMI nor DVI were
providing signal without it. Maybe the
situation is different because I am using a
core image and not a desktop one?<br>
</blockquote>
When booting Ubuntu Core, you shall see a
console on HDMI or DVI after the boot. You shall
not specify omapdss_def and you shall add splash
to the bootargs.<br>
<blockquote type="cite"><br>
6.) Are you sure about your pipeline? Here is
an example of pipeline supposed to work:<br>
Example of VTC (videoconference) e.g. V4L2 USB
webcam + preview + H264 encode + H264 decode +
display, using V4L2, DRI2 and PVR.<br>
gst-launch -v v4l2src ! "video/x-raw-yuv,

t. ! queue ! ducatih264enc
rate-preset=low-delay profile=100 ! h264parse

sync=false<br>
<br>
So I did a reboot, startx, export DISPLAY=:0,
checked lsmod again for "omapdrm_prv", and ran
the pipeline you provided:<br>
<br>
root@localhost:~# ./gst.sh <br>
