[Buildroot] buildroot Kernel from local directory

[astrolite .]

Hi all,
sorry for noob question, but i had a problem  understand the kernel options
in buildroot config.
For example:
If i have compiled my custom kernel (with relative patch and config)
outside buildroot, and copied into boot partion, it is necessary for the
purpose of compilation pass the path of the local kernel with relative
config file and dts files?

Thanks a lot,
Giovanni

You may build your kernel outside of Buildroot. You should only make sure that 
the kernel headers that are part of your toolchain are from a kernel version 
that is not newer than the kernel you run. When Buildroot builds your 
toolchain you may choose the headers version under Toolchain -> Kernel 
Headers. If you use an external toolchain it is up to you to get right.

Hope this helps,
baruch
