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.

Moto Defy MB525 CM7/CM9 TIWLAN MCP Calibration step by step

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
