TI OMAP Release PPA Update Announcement

[Boudet, Xavier]

Hello Panda board users,

TI will shortly update TI OMAP Release PPA (https://launchpad.net/~tiomap-dev/+archive/release) with some important updates.

This update shall come tomorrow February the 2nd.

People using the TI OMAP addons installed from the TI OMAP Release PPA will then be impacted.

This update will mainly consist of:

- New kernel: Ubuntu kernel will be replaced with Kernel 3.1, including:

* PandaES support (OMAP4460 at 1.2 GHz)

* DVFS support with on-demand governor enabled by default (CPU speed can be monitored with cpufreq-info)

* Thermal management

This kernel is largely based of Linaro kernel, and sources are available here: http://dev.omapzoom.org/?p=integration/kernel-ubuntu.git

- New Ducati Firmware, including:

        * H264 and MPEG4 encoders

        * H264, MPEG4, MPEG2 and VC-1 decoders

        * DCE

- Bluetooth packages

- Many fixes in other packages...

Some notes:

- You can re-install Ubuntu Kernel by installing back this Ubuntu meta-package: linux-image-omap4

- TI will only provide support to configuration using TI kernel and packages.

- You can report issues on Launchpad:

* https://launchpad.net/ubuntu-omap4-extras-multimedia

* https://launchpad.net/ubuntu-omap4-extras-graphics

* https://launchpad.net/ubuntu-omap4-extras-connectivity

- You can contact us on tioma...@lists.launchpad.net or on http://groups.google.com/group/pandaboard/

Thanks for the information. Those are great news for us Pandaboard ES users!

[Brian Albright]

Are these new drivers portable into the android ecosystem / kernel?

Update has been completed few minutes ago.

Upgrade using TI OMAP4 AddOns button shall work.

You can do it manually by adding TI release PPA (https://launchpad.net/~tiomap-dev/+archive/release) and then install ubuntu-omap4-extras packages.

For people already using this PPA, dist-upgrade shall be enough (note that you might need to run it twice).

After reboot,audio might be broken, if this is the case, execute following command once into user prompt:

* Panda: alsaucm -c Panda set _verb HiFi set _enadev Headset.0

* PandaES: alsaucm -c PandaES set _verb HiFi set _enadev Headset.0

hi group,

I met some problems after the upgrade.

1) I can not play this 1080p movies repeatedly like before.
My pipeline is not changed:
gst-launch playbin2 uri="file:///mymov.mov" video-sink="pvrvideosink"
In my old code ,I used the "about-to-finish" signal fuction to change
the uri of the next movie .
But after the upgrade ,the next movie can not play smoothly .
In the "about-to-finish" signal fuction I only set the new uri ,
Do I need to release the pipeline and rebuild it?

2) since I set the video-sink 's "force-aspect-ratio" to true ,
the playarea have black background uper and below.
After the upgrade , these 2 areas always flicker blurredly.
what can I do with it?

Eager for any hint!

Regards!
forrest

Do you think it is safe to run the board using the performance CPU
governor, i.e. at the maximum clockspeed all of the time?

Cheers,
John

Yes this is safe. If required, the thermal manager will reduce the max cpu speed, and that will scale the freq down even with performance governor.

[pavel sadowsky]

That's interesting - I think I saw this thermal slowdown already in
effect - before I attached a heatsink. Is there any documentation on
the thermal management, i.e. at which temperature the management will
slow down the CPU, and how the thermal policy is controlled?

Hi.

I have got ubuntu 12.04 server for ARM running on my PandaBoard, with openbox installed, and I installed ubuntu-omap4-extras-graphics and done a dist-upgrade, but when I try play a .mp4 file with totem, it says that the movie requires a "MPEG-4 AAC decoder plugin"...

I've looked at several threads in this group and around google but I can't quite pin what I'm doing wrong...

Any tips?

Thanks,

Dean.

enable multiverse and restricted archive in sources.list, and install
ubuntu-restricted-extras. it will install all the various codecs you
need.

audio codecs aren't accelerated in OMAP4, so you will end up using ARM
s/w codecs (ffmpeg/libav)

[E V]

Is there any place where the codecs included in h/w decoding are listed?

And also... in ubuntu webpage ( https://wiki.ubuntu.com/ARM/OMAP ) they say that the ppa is no longer needed. So, h/w decoding should work with just the image installed?

not sure. gst-inspect | grep ducati will give you the list.

hmm, that's for graphics only. ubuntu have made a copy of the TI SGX
drivers in their archive so that they can have a 'jokey -like'
installation (like on PC...).

for MM, there packages are available yet.

as i said on this forum already, you can peek at the omap-trunk PPA on
Launchpad to install the latest version of all packages (that includes
a newer kernel) and you will get new X driver, and new codec stacks
(reimplemented on top of new kernel + remoteproc/rpmsg). support for
GST is still not finished, though.

Is this PPA compatible with todays Ubuntu 12.04 updates?

I added the PPA using add-apt-repository and shortly thereafter automatic updates popped up.

When the updates completed, it said reboot required, but my system wouldn't reboot :(
All I got was a desktop background with five apparently empty "Untitled Folder" on it.

I did Ctr-Alt-F2 and got a console login but it wouldn't let me sudo so I was dead :(

I restored my SD card partition 2 from an rsync backup I made yesterday, booted up again and updated without adding the PPA and all seems well.

Needless to say I'm wary of this PPA now.

--wally.

can you specify more precisely what you've done exactly? e.g. did you
upgrade from 11.10 to 12.04, or did you make a fresh 12.04, then added
PPA and upgraded?
