OMAP4 BT Capture on McBSP2

Ramya Mohan1
Prodigy 130 points

Hi All,

We have already ported jelly bean 4.2.2 onto to OMAP4430 based custom board, based on 4AJ.2.5P1 release notes.

We have connected BT to McBsp 2 lines instead of McBsp 1.

In kernel, BT Capture & Playback are mapped to mcbsp2.

When we turn on BT SCO app to enable Music audio profile, the system & the console freezes

If we disconnect the BT headset, the system resumes back.

Any inputs?

Thanks in  advance.

Regards,

Ramya.

    Hello Ramya,

    The problem with BT SCO app can be caused because SCO routing in your Android is not enabled.

    Check this file /mydroid/system/bluetooth/data/ audio.conf - and enable SCO routing as remove "#":

    # SCO routing. Either PCM or HCI (in which case audio is routed to/from ALSA)
    # Defaults to HCI
    # SCORouting=PCM - old             SCORouting=PCM - new

    Try to turn on BT SCO app and test again.

    Enable Headset support because it is disabled by default. This change also must make in audio.conf file.

    # Configuration file for the audio service

    # This section contains options which are not specific to any
    # particular interface
    # NOTE: Enable=Sink means that bluetoothd exposes Sink interface for remote
    # devices, and the local device is a Source
    [General]

    #Old:
    Enable=Sink,Control
    Disable=Headset,Gateway,Source

    #New:

    Enable=Sink,Control,Headset,Gateway,
    Disable=Source

    Best regards,
