android4.0.3 BuleTooth 在pandaboard ICS上的成功移植

文件系统编译成功后，wifi可以直接使用了，但是bluetooth不能使用，以下是需要做的，按步骤来即可：

注：按照以下步骤操作经证实没有问题，切记接口为ttyO1，而非tty01，否则怎么都起不来的。

> Guys, I got it working in ICS master branch fromAOSPwith minimal changes and a re-compiled kernel:

> 3) modify device/ti/panda/ as follows:

> b) add android.hardware.bluetooth.xml from omapzoom blaze_tablet (http://git.omapzoom.org/?p=device/ti/blaze_tablet.git;a=blob;f=androi...)

> PRODUCT_PACKAGES := $(call inherit-product-if-exists, hardware/ti/wpan/)

> #shared transport user space mgr service forBluetooth, FM and GPS

> service uim /system/bin/uim-sysfs
>        class core
>        userbluetooth
>        groupbluetoothnet_bt_admin

> f - IMPORTANT) re-compile kernel fromAOSP: (

branch remotes/origin/android-omap-panda-3.0) with the following:

>        1) make sure you copy the original defconfig from arch/arm/configs/panda_defconfig to .config in kernel root
>        2) make menuconfig with ARCH=arm

>        3) Networking Support->Bluetoothsubsystem support->

>           a) turn on L2CAP, SCO, RFCOMM (with tty), BNEP, and HIDP

>           b)Bluetoothdevice drivers-> make sure you have HCI UART (H4 protocol) and Texas Instruments WiLink7 driver enabled

>        4) exit and save
>        5) re-compile, use the zImage (not the uImage) and replace the kernel in ti/panda/kernel with it.

> 4) Re-compileAOSPwith new kernel, see if BT and wifi works :-D

Thanks to richi-chen and .
I followed the steps given by and following are
some of the important changes which may require (for me without these
changes Bluetooth didn't come up)

In the init.omap4pandaboard.rc I have modified the following

on boot
        mount debugfs /sys/kernel/debug /sys/kernel/debug
        chmod 0666 /dev/pvrsrvkm
        chmod 0777 /dev/ttyO1        /* Added by me */
        chmod 0777 /dev/tty*
        chmod 0777 /dev/tty

and

service uim /system/bin/uim-sysfs
        class core

        user bluetooth
        group bluetooth net_bt_admin

        group bluetooth root     /* Added by me. But not sure is this really
required or not. Yet to try without having this line */

After this Bluetooth is started working. I mean able to see the
devices, not yet tried file transfer options
