Linux/WILINK-SW: After using new wl1271 firmware for solving KRACK, it seems the calibrator cannot work normally.

Part Number: WILINK-SW
Other Parts Discussed in Thread: WL1271

Tool/software: Linux

Hi TI experts,

I followed the instruction of applying patches for KRACK(both wpa_supplicant and firmware binary files).  The KRACK has definitely been fixed. But another issue appeared:

When do calibration like before:

calibrator plt autocalibrate wlan0 /system/lib/modules/wl12xx_sdio.ko /device/TQS_S_2.6.ini /data/misc/wifi/wl1271-nvs.bin 00:00:00:00:00:00

it will fail. The message and dmesg are as following:

1) message:

Fail to tune channel
Calibration not complete. Removing half-baked nvs

2) dmesg:

--------------------------------------------------------------------------------------------

All I have done are:

1) applay KRACK patch for wpa_supplicant.

2) replace 3 binary file: wl127x-fw-4-plt.bin, wl127x-fw-4-mr.bin, wl127x-fw-4-sr.bin.

If I only change the "wl127x-fw-4-plt.bin" back to the before revision, calibrator still can work normally. Paste the log here for your refrence:

1) the message:

Using nvs version 2.1

Calibration done. FEM1 has 1 bands. AutoFEM is off. Resulting nvs is /data/misc/wifi/wl1271-nvs.bin

2) the dmesg:

<6>wl12xx: firmware booted in PLT mode (PLT 6.3.10.0.137)
<6>wl12xx: power down
<6>remove wake up source irq 107

======================

My environment is:

1) Freescale i.MX6

2) Android4.3, wl1271(TiWi-BLE)

=======================

Could you help me to see where I am wrong? I believe your firmware should be compatible with the calibrator. I didn't see any change on the source code of the calibrator and TQS_S_2.6.ini.

Thanks and regards,

Vito Kang

    Or can I use old wl127x-fw-4-plt.bin for calibrator, and use new wl127x-fw-4-mr.bin, wl127x-fw-4-sr.bin for KRACK fix?

    Hi Vito,

    As you are using a claibrator from an older release, perhaps it would be better if you build the latest calibrator and try again:

    git.ti.com/.../ol_R5.SP9.01

    Thank you Eyal. Yes, I am using an old calibrator binary, because I didn't see any change of the calibrator code. Maybe I was wrong. In any case, I will build it as you said. I will tell you the result.

    Thanks again!

    Best Regards,

    Vito

    Hi Eyal, I checked out the latest code to build calibrator. The binary file "calibrator" compiled is totally same.The testing result is also same.

    I checked the commit log again, there is definitely no any other commit since Feb 25 2015, except the 6 firmware .bin files committed this time for KRACK.

    Maybe something else?

    Thanks & best regards,

    Vito

    Hi Vito,

    We are going to look into why the PLT firmware from version 142 is not working as expected.
    However, there has been no change which is relevant to PLT mode between FW137 and FW142 so for now you can continue using the PLT firmware from PLT 6.3.10.0.137.

    Best Regards,
    Eyal

    Hi Vito,

    Can you try the attached new PLT firmware files for version 142 and see if they are working for you?

    wl128x-fw-5-plt.bin

    Or:

    wl127x-fw-5-plt.bin

    You may need to rename them to the name used by your kernel (wl127x-fw-4-plt.bin)

    BR,

    Eyal

    btw, I found that the prefixes of PLT versions are a bit different. The prefix of the version that can work is always "PLT", like PLT 6.3.10.0.137, PLT 6.3.10.0.142. The prefix of the version that cannot work is "Rev", like Rev 6.3.10.0.142. Don't know if this can help you.:)

    Hi Vito,

    Good this is expected. wl128x-fw-5-plt.bin is for wilink7 and you are using wilink6.

    We will also update the git with the correct firmware for plt mode.

    Best Regards,

    Hi Eyal,
    Good! After your official release, I will also test it again.:)
    Thanks a lot!
