Adding drivers to Yocto raspberry pi image

I want to add the AD5628(http://cateee.net/lkddb/web-lkddb/AD5064.html) DAC Device drivers to kernel in the yocto.

So i have build a yocto image for raspberry Pi by following the guide http://git.yoctoproject.org/cgit/cgit.cgi/meta-raspberrypi/about/

Now i want to add the Dac Driver module to kernel so i tried to bitbake command

bitbake -c menuconfig rpi-hwup-image

so that i can get a configuration menu and can add the drivers . But it is giving me error saying that menu configure does not exists for the target . So i tried 

 bitbake linux-raspberrypi -c menuconfig

But i am getting error

"there was error creating child process for this terminal, failed to execute child process "oe-gnome-terminal-phonehome" (no such files or directory) ".

So someone please help me to add AD5628 driver to the kernel . Thanks

Solution

  • we need to create a .bbappend file in the meta-layer directory (in my case it should be meta-raspberrypi) , The contents of bbappend file should be 

    SRC_URI += "file:///path/to/config.cfg"

    then create a config.cfg in the same directory and contents should be 

    CONFIG_AD5604 = y

    I have given the name AD5604 because that driver suports the ad5628 device.

    thanks for the support
