Thanks Bruce for the answer,
So I did:
#bitbake -f -c compile core-image-minimal
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.
