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. Description : Sans titre Morgan Guillou Tel :+33 6 87 59 16 28 Batiment Le Kerguelen 7 rue LT De Vaisseau Bourely 56100 Lorient
