adding new kernel defconfig

adding new kernel defconfig

[G. Eismann]

Hi there,

I am new with openembedded and I am trying to build a kernel for a new 
machine.

In my machine config file I have these lines:

PREFERRED_PROVIDER_virtual/kernel = "linux"
PREFERRED_VERSION_linux = "2.6.25"

When I build the kernel, bitake downloads a 2.6.25 kernel: OK
But it takes the kernel config from recipes/linux/linux/defconfig

I have added my own defconfig file in 
recipes/linux/linux-2.6.25/mymachine/defconfig but I dont know how to say 
bitbake to use it.

    Regards

If you have set MACHINE=mymachine and are using a DISTRO configuration which 
includes a reasonable set of OVERRIDES; then $MACHINE is included in these 
OVERRIDES; which means, bitbake will copy $MACHINE/defconfig (if present) into 
$WORKDIR.

MACHINE is set in my local.conf file.
I've also added a line with DEFAULT_PREFERENCE_mymachine = "1" to 
linux_2.6.25.bb although I am not sure if this is correct.

The DISTRO configuration had no OVERRIDES line. I have copied the OVERRIDES 
line from minimal distro ($MACHINE is included in it), but bitbake is still 
taken the defconfig from linux/defconfig
