[oe] How does OE determine the kernel version that gets build?

[Lars Holowko]

Thanks Khem,

I'd swear that that line was not in conf/machine/at91sam9g20ek.conf but
that would make me look even siller, wouldn't it? ;-)
You saved me from going crazy...

Everything works fine.

Lars

because in conf/machine/at91sam9g20ek.conf it says it wants 2.6.28

PREFERRED_VERSION_linux = "2.6.28"

change that and it should pick whatever you chose instead of 2.6.28
