    Hi Vivek,

    Please note that we support linux kernels running on TI devices only. IMX6 devices are not TI products.
    Please refer to the corresponding vendor support team.

    Dear Yordan,
    Thanks for your reply.

    I have download ti wl18xx patches from --
    git clone git://git.ti.com/wilink8-wlan/build-utilites.git

    I have seen many patches are available as per kernel version.

    Also some script files are provided.

    My doubt is that if I apply these patches to my kernel and then build the kernel then is it sufficient for me to up wifi and BT ?
    Or need I also run build_wl18xx.sh scripts ?

    Please guide.

    With Regards,

    Hi,

    For your device (imx6) the kernel patches should be enough. Then you should build the kernel as per the guidelines in the imx6 sdk (I am not familiar with it).

    The build_wl18xx.xh scripts provide instructions to build for TI devices:
    make -j${PROCESSORS_NUMBER} zImage
    make -j${PROCESSORS_NUMBER} am335x-evm.dtb
    make -j${PROCESSORS_NUMBER} am335x-evm-wow.dtb
    make -j${PROCESSORS_NUMBER} am335x-bone.dtb
    make -j${PROCESSORS_NUMBER} am335x-boneblack.dtb
    make -j${PROCESSORS_NUMBER} am335x-boneblack-e14-wl1837.dtb
    make -j${PROCESSORS_NUMBER} am335x-boneblack-su-audio.dtb
    make -j${PROCESSORS_NUMBER} am335x-boneblack-wl1835.dtb
    make -j${PROCESSORS_NUMBER} modules

    Best Regards,
    Yordan

    Dear Yordan,
    Thanks for your reply.

    I have applied TI WL18xx patches to my kernel version 3.14.52 manually.

    When I boot the linux os on my board. I cant get any wlan0 interface after typing iconfig or iwconfig.

    Is there any patches available which are doing changes in rootfile systems.

    Please guide.

    Not that I know of. But you can create init scripts to start your wlan0 & configure it upon boot up.

    Best Regards,
