    Thank you,

    Netherless I see it is the entire kernel source in the git repo with the driver of wolfson and probably many else stuff.

    I would like to have just a patch to add to the kernel source  that i have already mainly I'm not used with git.

    Hope this helps.

    Can someone please explain this step in the "3.12.y A New Try" instructions:

     

    "and copy to root of the Raspberry Pi".....

     

    Copy which files/folders?  And how exactly?

     

    Many thanks.

    @ a d :

    when you extract the sentence from the context this makes no sense.

    the fully intructions of 3.12.y A New Try are :

    mkdir kernelAndFirmware_wolfson_r

    tar -xvjf kernelAndFirmware_wolfson_rt.tar.bz2 -C kernelAndFirmware_wolfson_rt

    and copy to root of the Raspberry pi.

    So I guess , you extract with tar command the files/folders in the dir KernelAndFirmware_wolson_rt , then you need to copy these extracted files/folder in root directory

    so the command recursive copy is : cp -r  (source) (destination)  ; then you take all the files in wolfsonAnd... dir (the source) : WolsonAnd.../*  ; then you say the root dir : / (the destination) .At the end you have this command to type :

    # cp -r KernelAndFirmware_wolson_rt/*  /  ;

    Sorry everyone, I should expand; - I did it "the hard way" (instructions at the bottom) by compiling the entire kernel etc.

     

    I needed to do this because I also had a non-standard wifi USB dongle that needed drivers compiled.

     

    It takes longer (14 hours) but it does work.

    Hello everybody,

     

    I also try to compile the wolfson audio card for the kernel 3.12. I have a question about the instructions above. Is: sudo cp -r KernelAndFirmware_wolson_rt/*  /  the right command to copy the datas into the root-register? Where exactly can I find the command kernel=kernel.img in the /boot/config.txt. It's very urgent for my project. I hope someone can help me! Sorry I'm a beginner;)
