TI WLAN NLCP calibration

Platform: Nook Color ICS with WiFi Direct

1. mount system partition readable/write-able

mount -o rw,remount /dev/block/mmcblk0p5 /system

2. unload driver

rmmod wl12xx_sdio

3 generate reference nvs for calibration

calibrator set ref_nvs /system/etc/wifi/ini_files/127x_TQS_S_2.6.ini /system/etc/firmware/ti-connectivity/wl1271-nvs.bin
4. reload the driver 
insmod wl12xx_sdio

5. Power on the device in PLT mode

calibrator wlan0 plt power_mode on

6. TX-BIP procedure

calibrator wlan0 plt tune_channel 0 7

calibrator wlan0 plt nvs_ver 0x0403

calibrator wlan0 plt tx_bip 1 0 0 0 0 0 0 0 /system/etc/firmware/ti-connectivity/wl1271-nvs.bin

7. Write MAC

calibrator set nvs_mac /system/etc/firmware/ti-connectivity/wl1271-nvs.bin 08:00:28:31:32:33

ICS WiFi Direct understanding

The Android 4.0 (ICS) WiFi Direct didn't support any service discovery or any default application ( one demo program) .

The implementation only take care the connection.

That mean the ICS take care two p2p device set up the TCP/IP networking well and other is application specific job.

Turn on USB ADB debugging

Connect to defy through adb

1. Turn off Wifi First

svc wifi disable

2. load wifi driver

insmod /system/lib/modules/tiwlan_drv.ko

3. load wifi firmware

/system/bin/wlan_loader -f /system/etc/wifi/fw_wlan1271.bin -i /system/etc/wifi/tiwlan.ini

4. turn on tiwlan0

ifconfig tiwlan0 up

5. execute wlan_cu utility

wlan_cu -b

6. execute following command

/ w p 1

/ w l 2

/ w f 2

/ t r h 0 7

/ t b b 375 128 0

/ t b t 1 0 0 0 0 0 0 0

/ q

7. copy new calibration data to default path

cp /data/misc/wifi/nvs_map.bin /pds/wifi/nvs_map.bin

sync

sync

8. unload TI wlan driver

rmmod tiwlan_drv

Build Andorid environment setting

Ubuntu Linux (64-bit x86)

This has not been as well tested. Please send success or failure reports to android-porting@googlegroups.com.

The Android build requires a 32-bit build environment as well as some other tools:

• Required Packages:
• Git, JDK, flex, and the other packages as listed above in the i386 instructions:
  
• JDK 5.0, update 12 or higher. Java 6 is not supported, because of incompatibilities with @Override.
• Pieces from the 32-bit cross-building environment
• X11 development
  

$ sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl sun-java5-jdk zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev

• Set the system to use the right version of java by default:
  
  $ sudo update-java-alternatives -s java-1.5.0-sun
  

• X11: Ubuntu doesn't have packages for the X11 libraries, but that can be worked around with the following command:
  
  $ sudo ln -s /usr/lib32/libX11.so.6 /usr/lib32/libX11.so
