[yocto] Compiling kernel from external source in Yocto

[Sudhangathan B S]

Thanks Bruce, I now understood a little more..!

So if I put the defconfig file in the place it is looking for (kindly note,
it is looking for defconfig within yocto folders, it is is not looking for
defconfig in my external src directory), it then throws this error:

NOTE: Executing RunQueue Tasks

for further information)

Now I hope you have more information...!!
My external src directory has got the .config file.
