AM335x StarterKit WL1271 Calibration Instructions

Michael Questo
Expert 6000 points
Other Parts Discussed in Thread: WL1271
 
Command Format:
   
    calibrator plt autocalibrate <dev> <kernel mod> <ini> <nvs> <mac>
 
Instructions:
1. Remove (and/or back up) existing calibration file
 
    mv -f /lib/firmware/ti-connectivity/wl1271-nvs.bin /lib/firmware/ti-connectivity/wl1271-nvs.bin.bck
 
2. Disconnect WiLink module by removing SDIO driver module
 
     ifconfig wlan0 down  rmmod wl12xx_sdio.ko
 
3. Perform calibration - this command uses the ini for the murata module on the AM335x starterkit
 
    calibrator plt autocalibrate wlan0 /lib/modules/$(uname -r)/updates/drivers/net/wireless/wl12xx/wl12xx_sdio.ko /usr/share/ti/wifi-utils/ini_files/127x/TQS_S_2.6.ini /lib/firmware/ti-connectivity/wl1271-nvs.bin 10:20:30:40:50:60
 
4. Reconnect SDIO module by loading driver module
 
    modprobe wl12xx_sdio   5. Bring up Interface and test WLAN
    ifconfig wlan0 up  iw wlan0 scan
 
 
Sample Output running on SDK 6.0.0 on the Starterkit:

    Hi Micheal

    Looks like calibration is broken .I am using TiWi5 and could not do the Calibration .Except Calibration WiFI is working fine ,i can scan and connect to WIFi networks.

    Below is the command i am using to calibrate .let me know if something wrong with command. 

    calibrator plt autocalibrate wlan0 /lib/modules/$(uname -r)/updates/drivers/net/wireless/wl12xx/wl12xx_sdio.ko /lib/firmware/ti-connectivity/ini_files/127x/TQS_D_1.7.ini /lib/firmware/ti-connectivity/wl1271-nvs.bin 00:00:00:00:00:00

    Hi Sunil,

    Do check for:

    1. Place right .INI file at /usr/share/ti/wifi-utils/ini_files/127x on target.

    2. Modify /etc/rc5.d/S20calibrate.sh to point to file in step 1 on target.

    3. Check for correct clock frequency at from TI Wiki reference and modify the same at arch/arm/mach-omap2/board-am335xevm.c and rebuild the kernal.

    hope this helps.
