wl1271 calibration problem

Timo Lange

Other Parts Discussed in Thread: WL1271

Hi,

I have a TiWi-BLE modul on a i.MX6 processor. The w-lan seems to work correctly. I can scan with „iwlist wlan0 scan“ without problems. But the calibration don't work. I searched in this forum but there was no answer which could helped me.

    Hi Timo,

    The error:
    "wl12xx: ERROR command execute failure 2"

    suggests that the firmware did not understand a command that was sent to it. This can happen if there is a mismatch between the firmware & the calibrator tool versions. Please confirm if you have pushed the right version of the calibrator to your device.

    If it doesn't work, I suggest that you upgrade to the latest release "ol_R5.SP7.01"

    Regards,
    Gigi Joseph.

    With the release "ol_R5.SP7.01" all works fine. Thank you!

    Hi Joseph,

    While testing the wl1271 interface for Tx/Rx or calibrating, I am getting the following error script. Please help me overcome it.

    While booting the wlan, the following lines show in the log related to backport version.

    [   29.569976] Compat-wireless backport release: ol_R5.SP7.01
    [   29.575805] Backport based on wl12xx.git ol_R5.SP4.01-2-g1aa2c8e

    Please let me know this is proper or not. If ol_R5.SP7 is required, please let me know the procedure to make this update.


    Thanking you in advance,

    Anindya

    Hi Anindya,

    Please follow the wl12xx build script from https://github.com/TI-ECS/build-utilites/blob/master/wl12xx_build.sh
    and change "gen_tag" in the script to "ol_R5.SP7.01" and build.

    The error you are getting seems to be again related to the building - the firmware you are using is probably not the latest

    Regards,
    Gigi Joseph.
