Wilink8 backporting bluetooth module for 2.6.37

Hi Mike,

We don't have any official version...

Regards,
Gigi Joseph.

Hi Joseph,

Can you point me to unofficaial version please ? I have got the wifi working.

Thanks And Regards,
Mike

Hi Mike,

I'm sorry if I have confused you... There is no such version. I think the best way would be to use the shared transport driver that is part of the 2.6.37 kernel.

Regards,
Gigi Joseph.

Hi Mike,

Sure...

1. In your defconfig, enable CONFIG_TI_ST & CONFIG_BT_WILINK* (ensure also that CONFIG_BT is set).
2. Get "uim" source from: https://gitorious.org/uim and cross compile for your platform
3. Get the BT firmware from: git://git.ti.com/wilink8-bt/ti-bt-firmware.git and copy: TIInit_X.X.XX.bts to "/lib/firmware/"
4. Start the uim during boot
5. Issue standard BlueZ commands (hciconfig hci0 up/down, hcitool inq, etc).

(*) AFAIK, CONFIG_BT_WILINK is available only from 2.6.39. So that driver needs to be ported (/drivers/bluetooth/btwilink.c)

Regards,
Gigi Joseph.

Hi Joseph,

Sorry for the delay I was on a holiday for a month!

1: What BT firmware needs to be used for 8148
2: Correct me if I am wrong the wilink8 wifi driver (backporting) is independent and has nothing to do with bluetooth ?
3: Can you point me to 2.6.39. So that driver needs to be ported (/drivers/bluetooth/btwilink.c)
4: Should I use bluez or bluetopia ? any links on to cross compiling this stack ? (I see that both stack support all the profiles that I need)

Thanks And Regards,
Mike

Ping.

Hi,

1. BT Firmware depends on the WL18xx device you are using,you can get the latest SP from here git.ti.com/.../master
2. yes it has nothing to do with Bluetooth.
3. You can search it online, the one I could find is lxr.oss.org.cn/.../btwilink.c
4. BlueZ, if you are using btwilink

Hi Sundeep,

Thanks that helped me.

I can see the driver is being called following is the boot log:

[ 2.000000] Bluetooth: Bluetooth Driver for TI WiLink - Version 1.0
[ 2.010000] hdev d6782800
[ 2.010000] HCI device registered (hdev d6782800)

But I am still not sure who loads the firmware & which firmware do I need to
use for wl18xx device ?

I have also bluez in my filesystem how do I need to proceed further ?

Thanks And Regards,
Mike

Hi,

Some update, I did the following:

$ uim &
[1] 183
uim:@ main
uim:install = /sys/devices/platform/kim/install
uim:dev_name = /sys/devices/platform/kim/dev_name
uim:baud_rate = /sys/devices/platform/kim/baud_rate
uim:flow_cntrl = /sys/devices/platform/kim/flow_cntrl
uim:begin polling...
$ hciconfig up
hci0: Type: BR/EDR Bus: UART
BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0

TX bytes:0 acl:0 sco:0 commands:0 errors:0

$ hciconfig hci0 up
Can't init device hci0: Operation not possible due to RF-kill (132)

But I am still not sure which firmware needs to be used by the wl18xx device & how to load.

Thanks And Regards,
Mike

Hi,

Further update this is what I did after bootup:

$ uim &
[1] 183
uim:@ main
uim:install = /sys/devices/platform/kim/install
uim:dev_name = /sys/devices/platform/kim/dev_name
uim:baud_rate = /sys/devices/platform/kim/baud_rate
uim:flow_cntrl = /sys/devices/platform/kim/flow_cntrl
uim:begin polling...
$ hciconfig hci0 up

$ rfkill list

$

But still no luck!

Thanks And Regards,

Hi,

Looks like GPIO is not toggled properly.

This should be high before there is any communication with the chip.

Could you please check if the connection with the chip is fine when you face this issue. Also if possible please check if the voltage on GPIO is driven high.

Also probe the UART lines to make sure that the UART configuration is correct.

also make sure that you are using the correct from location git.ti.com/.../master

Hi Sundeep,

But I thought nshutdown_gpio in pdata did that, do we need to explicitly do that ?

And also I am using TIInit_12.8.32.bts firmware how does this firmware get loaded ?

Thanks And Regards,
Mike

Hi Sudeep,

The GPIO pin is correct I have verified, I have moved a further ahead but still not there, following is the issue I am facing now:

Hi,

From the logs you have posted it looks like BT is UP and running.

Hi Sundeep,

But when I do scan I dont get any device listed:

# hcitool scan
Scanning ...
#

And also when I scan through my mobile device I nor do see my device.

Thanks And Regards,
Mike

Hi,

By default the antenna configuration is mapped to U.FL (external) connector (C7 and C8 are connected) in COM8. Which has to be changed to C5 and C6 capacitors, for routing it to internal antenna. So the range will be very less. Could you keep it side by side and try.

also make sure that the page and inquiry scans are running (enabled)

Please make sure you are using the right service pack from here git.ti.com/.../master.

Hi Sundeep,

I did try with the antenna connected keepeing the devices very close enough, but still it doesnt list out my mobile device.
Is it that it only works when wifif driver is enabled ? (because I have turned of the wifi module). Seems its getting the
mac address but I am not able to discover it on my mobile device.

I am using the bt_wilink driver from 2.6.39 kernel ? were there any bug fixes or something for this and I need to upgrade or something ?

Thanks And Regards,
Mike

Hi,

I don't think it is related to the WiFi driver, Could you please let me know the size of the SP you are using? it should be around 69Kb.

Hi Sundeep,

Its around 72K.
