Facing problem on enabling WL1271 on Android 2.3.4

Hi All,

I have ported android on DM3730 and I want to enable Bluetooth and WIFI on Android 2.3.4 (Gingerbread).

kernel : rowboat-kernel-2.6.37-variscite

File system : AM37X

I performed necessary changes as per TI's document :

http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_PortingGuides

1) In WIFI, All other configuration are already there, I am bit confused about "corresponding patch Added emulation of Android private ioctls for generic WiFi drivers"

How to apply above patch ??

2) In Bluetooth, I already performed changes in Boardconfig.mk , init.rc files  in android filesystem and kernel configuration as per above document. but when i starts bluetooth from settings , at that time i get the state change event (in my logcat) but could not get the enable bluetooth.

Error Logcat :

    This type of error is usually seen when there are issues with the power-up sequence of the BT module.

    We would recommend that you first verify that the Bluetooth works from command line before trying it from android settings.

    Hi Vishvershwar,

    I agree with your recommendation, Can you please provide me steps for verification of Bluetooth and WIFI from command line ?

    Thanks,

    Nimit

    If you study the init.rc file carefully, you can see which commands to run on the console.

    e.g from http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_PortingGuides#Android_BT_HAL_Configuration

    - to power on BT module on omap3evm:
    /wl1271bt_enable /dev/ttyO1

    - to start bluetooth
    /system/bin/hciattach -n /dev/ttyO1 texas 3000000

    For Wi-Fi, I would suggest to first check using a linux kernel and filesystem. You can find some details at the following link:
    http://processors.wiki.ti.com/index.php/OMAP35xx_Wireless_Connectivity

    I'm not sure, but it seems like you are using the legacy WiLink driver which is not supported on TI Android 2.3.4 DevKit. It uses the newer open source OpenLink mac80211 drivers

    You may wish to refer http://processors.wiki.ti.com/index.php/ARM_Processor_Open_Source_Wireless_Connectivity for more details on this.

    Hi Vishvershwar,

    I am going to refer that document for WIFI.

    Can you please suggest me any work out for Bluetooth ?

    Thanks

    Hi Vishveshwar,

    I am using following AM37x  filesystem:
    http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Android_GingerBread_2_3_4_DevKit_2_1/exports/AM37X.tar.gz

    Could you please let me know that , this filesystem supports WL1271 or not?

    Thanks,

    Nimit

    The package you referred to supports both Wi-Fi and Bluetooth with WL1271 on the AM37x/omap3evm platform. This is also mentioned in the release notes:

    Hi Nimit,

    Are you able to fix the wifi problem?

    Same problem is reproduced in my setup using DM3730 (Filesystem over NFS).

    From the observation i realize  that  wlan0 is not getting created which should be created during the inserting the wl12xx_compat modules, hence  IOCTL errors.

    Below are the logs:

    Please guide me on this.

    Thanks,

    Rithesh

    Hi Rithesh,

    There are some known issues when enabling wifi from an NFS mounted file system. Some issues in co-existence of Ethernet/Wifi. Could you please check Wifi from an MMC file system?

    Arun

    Hi Arun,

    Thanks for your reply.

    I have not yet started the work on integration of the MMC on DM3730.

    But your lead on the MMC helped to setup properly/initialize MMC2 required by the Wl12XX driver. No wl1271 firmware is loaded and there are no error regarding the IOCTL's.

    Though the wifi issue is not yet solved since i am stuck at the scanning phase , where scan doesnot provide me any network details, hence unable to connect to any network.

    Please see the log below:
