Hi Geoffroy,
I have reproduced the exact same issue has you described.
Basically, you can find the defconfig files in
meta-tizen/meta-tizen-adaptation/meta/recipes-kernel/linux/linux-yocto/ .
During the do_kernel_configme step, the passed defconfig file seems not
to be taken into account, and as a result, it generates an other one
which enables some x86_64 based configs. (as you have already noticed in
the .config file).
I'm currently working on that issue, but in the mid time here is a dirty
work around that could help you to generate an image :
1. Once linux-yocto has crashed, tape the following : bitbake
linux-yocto -c menuconfig
2. Disable the 64-bit kernel option (must be the first option), Esc and
save the conf (enter)
3. relaunch the kernel build : bitbake -kv linux-yocto
Hope this could help!
Regards,
Xavier

Excuse the newbie question but where exactly can I find these defconfig files?
I thought they were part of the kernel sources but you seem to indicate they
are actually somewhere in meta-tizen but I couldn't find them there?
I noticed the following messages in log.do_kernel_configcheck:
<snip>
[required redefined (2)]:
.meta/cfg/standard/genericx86/required_redefinition.txt
required kernel config options were redefined (and changed)
during processing this BSP. This means that required values are
are changed from their initial value.

</snip>
What does that mean and what triggers this?
Here is some additional info that may be useful to the experts out there.
log.do_kernel_configme file:

Hi,
We already encountered that issue which was due to a wrong defconfig
being used (x86_64 instead of i586 or the opposite). I suspect this is
also the case with your current issue. You can easily check that by
deleting all but the correct defconfig in meta-tizen, cleaning the
kernel build and try it again. If it succeeds it means the wrong
defconfig is being used and we will have to investigate why.

Hi All, I tried to build Tizen IVI Modello 32bit image ,but failed at linux-

Can you provide more information, just as the contents of your local.conf file
in the build area, also what steps you did leading up to tihs? Was it from an
existing build or a clean build?
Thanks
Sau!
