[meta-intel] Atom E3845: Kernel build issues

[Prasant J]

Hi,


I'm building yocto distro for my custom hardware based on intel Atom E3845.
Below is my yocto build configuration:

BB_VERSION        = "1.24.0"
BUILD_SYS         = "i686-linux"
NATIVELSBSTRING   = "Ubuntu-12.04"
TARGET_SYS        = "i586-poky-linux"
MACHINE           = "valleyisland-32"
DISTRO            = "poky"
DISTRO_VERSION    = "1.7.1"
TUNE_FEATURES     = "m32 core2"
TARGET_FPU        = ""
meta
meta-yocto
meta-yocto-bsp    = "(nobranch):ff482c2522f7092216a4ac7b335393a5294d97d5"
meta-msc-ldk-core = "v0.4.0:ed047edacf285e711c55ed8389111981abc417c7"

meta-valleyisland = "(nobranch):5af06a8b0dd28498e77581f6bcb7fd6f722b755a"
meta              = "(nobranch):56c6bebdd19b5b64a2585986299543abf6e6ad48"



I have changed kernel configuration and successfully built it
(arch/x86/boot/bzImage), but when I copy the newly built kernel to my
target hardware I do not see the relevant changes.
I check my kernel config (zcat /proc/config.gz) and my updated
configuration is not there.


After updating the configuration, I can see the relevant files being built
(that confirms my changes were applied) also I can see my updated
configuration is (kernel_source_code/include/config.gz).
So why can't I see the new configuration on the target hardware?


I also tried building the kernel outside the yocto build system (used the
SDK to build the kernel). Same observations.


I have worked for many years on embedded ARM linux systems but I have never
come across such a puzzling observation. Any one get any ideas what I may
have missed or what I may be doing wrong ?


Thanks in advance!
