Thanks Bruce,
It was not exactly what I ran, I ran that:
$ bitbake core-image-minimal -c compile -f
This should rebuild only the kernel as I read in that doc:
https://www.yoctoproject.org/sites/default/files/kernel-lab-1.6.pdf
Sorry, I'm not used with linux, I'm right or not ?
You need to force the compile of the kernel package, not the
image type.
So whatever recipe is providing your kernel, that is the name
you should be using.

Thanks Bruce for the answer,
So I did:

This should have been your kernel recipe, not the image. Did you typo that ? Or
is that what you really ran ?
Bruce
#bitbake core-image-minimal
It repackaging rootfs.ubi and ubi files, but no dtb files !
What's wrong ?

I've been working with hardware sama5d35-xplained.
I used the at91 tutorial to compile and install yocto distribution on
the target, that's fine.
My next step is to redefine one interface that is custom to my board,
I want to enable the USART2.
I modify the dts file:
"/poky/build-atmel/tmp/work-shared/sama5d3-xplained/kernel-source/arch/arm/boot/dts/at91-sama5d3_xplained.dts"
to add :
usart2: serial@f8020000{
Pinctrl-0 = <&pinctrl_usart2>;
Status = "okay":
};
Maybe I'm just tired, or maybe this is just hard... but the dtb file
is not updated when I run bitbake.
bitbake won't know that you've updated the source. So you'll need to force a
re-compile of the kernel, and then rebuild your image.
bitbake -f -c compile <your kernel recipe>
And then you should see things repackaging next time you build the image.
Bruce
So do I have to manually compile the dts file or is there some way to
do it via "bitbake core-image-minimal" ?
Thanks,
Morgan.
