OMAP 4460 + ducati + linux ubuntu

Ramakrishna Rao KV
Prodigy 30 points
Other Parts Discussed in Thread: 4460, TWL6030

Dear all,

 

We have TI OMAP4460 based custom board (used Jorjin POP module).

We would like to use Gstramer, Open MAX, sys-link/RPMsg frame work with Ducati for multi-media features for Linux 3.0.3 based kernel (monta Vista / normal linux)

 

In this context we have couple of queries...

 

1) Does Linux 3.0.3 kernel supports TI multimedia features to enable on 4460?

Do we need to apply any patches for it? or which TI kernel which supports these features.

 

2) Ducati binaries downloaded using following link

https://gforge.ti.com/gf/project/openmax/frs/

Could you please confirm is this the right place? any other place available.

 

3) Where to place the Ducati binaries on file system?

is it ti-connectivity folder or any other place?

 

Thanks in advance

 

regards

Ramakrishna

    Hi Ramakrishna,

    Could you let me know where have you downloaded the linux kernel from? Ducati binaries are not released as a standalone entity, it is packaged along with a particular distribution and hence the question.

    Dear Satheesh

    We have downloaded the linux kernel from kernel.org it is plain vanilla kernel v3.0.3 and configured for 4460 for our custom board.

    We would like to enable Ducati and multimedia applications on top it.

    Thanks

    Ramakrishna

    Hi Ramakrishna,

    It is better to use the TI OMAP PPA release for ubuntu.  It only supports Pandaboard and includes hardware accelerated codecs (DCE)  that works with gstreamer as well as GFX DDK. However this release does not support any OMX decoders or camera.

    Please download it from the following link:

    https://launchpad.net/~tiomap-dev/+archive/release.

    Ramakrishna,

    Here is step-by-step guide to set up a Panda board, install an Ubuntu image on SD card, and then add the TI OMAP PPA release.

    http://omapedia.org/wiki/Ubuntu_Pre-built_Binaries_Guide

    Then multimedia features work off the shelf. For instance, totem will play H264, MPEG4, MPEG2 and VC-1 video clips using codecs on Ducati.

    It is based on kernel 3.4 with TI patches.

    I find this silly. Why is it only supported for the Pandaboard? There are other OMAP4 boards out there (Gumstix Duovero was released no more than a month after the PPA release). I'll be honest, I'm slightly disappointed in the amount of development that has gone into the DCE and IVAHD high level workings. I've searched the internet long and hard and still can't find any suitable solution for my issue. However, seeing as you will be phasing out the OMAP family after 5, kind of expected. I'm having huge issues trying to get the PPA to work. Do I have to use the kernel build that TI provides? I'm using Linux 3.6.0 and TI's build is 3.4.x. When I try to implement the TI kernel, it messes up due to incompatibility.

    Any help would be appreciated; sorry for the "bashing."

    Thanks,

    Mike Seese

    Mike,

    Fact is that some TI patches were upstreamed, some are still in the patch queue. A vanilla 3.6.0 kernel does not include the DCE patches required for video acceleration. You may either stick to TI 3.4.x kernel, or try to rebase TI patches on 3.6.0 (the latter is tough).

    Please bear in mind that TI cannot realistically support all kind of kernels and boards at all times. Contributions from third parties are welcomed.

    After booting the processor we are receiving following message and booting stops then and there.

    Hi.

    You can use TI Ubuntu kernel as base point for customizing it to your system.

    Basically it has support only TI's kits but no one forbid to add description of your platform. So feel free to add your plaftorm file and you will get customized TI's kernel.

    In fact 3.4.x branch is stable enough...it still has some of issues for example USB OTG works with bags very often.

    I do not use HW codecs but at least Ducati code load without errors.

    WBR,
