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