no tidspbridge support in kernel.

Bug Description

SRU Justification:

    Impact: user code cannot communicate with the DSP hw.
    Fix: see attached patch.
    Testcase: see if /dev/DspBridge exists.


Platform used : Beagleaboard xM RevC
lsb_release -rd :
     Description : Ubuntu 12.04.LTS
     Release : 12.04

The Linux config is compiled with staging support but without the DSP support (checked int the /boot/config file) so we cannot make the gst-dsp work without recompiling the kernel.

I had to install a 'maybe non official' kernel image following this steps (RobertCNelson kernel)

I think it is better to have the dsp compile as module in the officiel distribution so we are sure that it has been generated with the same environnement, and be sure to retrieve it with the source.

Thanks for processing my request.

note : the module has been compiled with these options :
mempool size = 0x600000
debug = n
recovery = y
cache check = n
wdt = y
wdt timeout = 5
notify power err = n
backtrace = n
ApportVersion: 2.0.1-0ubuntu13
Architecture: armhf
DistroRelease: Ubuntu 12.04
Package: linux (not installed)
 PATH=(custom, no user)
Tags: precise running-unity
Uname: Linux 3.2.30-x14 armv7l
UnreportableReason: The running kernel is not an Ubuntu kernel
UpgradeStatus: No upgrade log present (probably fresh install)
UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1058022

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This bug is awaiting verification that the kernel for Precise in -proposed solves the problem (3.2.0-33.52). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-precise' to 'verification-done-precise'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See for documentation how to enable and use -proposed. Thank you!

Hello Luis,
If my verification is still needed plz wait until wednesday, I was really busy those days and just recently got my BB xM.

yes, we still require the verification for this fix. Thank you for your time helping with it.

Hello, as I did not find this image, I just called apt-get update & upgrade (as Paolo told me to do) and installed the last linux image available (3.20-32), in which the tidspbridge module is not available.
So I do I get this 3.2.0-33 ?
