Hello community,
I am using the Colibri iMX6 and trying to configure the GPIO pins by using device-tree-overlay.
I am using the BSP 5.7.
I have created a device-tree-overlays_%.bbappend and attached my custom devicetree files under the */file directory as .dts extension.
I am adding this dts to the bbappend and building with bitbake device-tree-overlays
// Example file that disables usbotg
/dts-v1/;
/plugin/;
&weim {
status = "disabled";
};
It is evaluating as dtbo but
I am attaching this,
/dts-v1/;
/plugin/;
#include <dt-bindings/input/input.h>
#include <dt-bindings/interrupt-controller/irq.h>
#include <dt-bindings/pwm/pwm.h>
#include "imx6dl.dtsi"
#include "imx6qdl-colibri.dtsi"
#include <imx6dl-pinfunc.h>
/ {
compatible = "toradex,colibri_imx6dl", "fsl,imx6dl";
fragment@0 {
target-path = "/gpio-keys";
__overlay__ {
compatible = "gpio-keys";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_gpio_keys>;
left-key {
label = "GPIO Left Key";
gpios = <&gpio3 70 0>;
linux,code = <KEY_KP4>;
};
};
};
};
when i build it with bitbake device-tree-overlays it is not evaluating as dtbo.
What is the reason that I could not see. Could you please helpβ¦
Best Regards.

Also it is the log output.
And also my custom devicetree file is appended at the git dir at the build tmp

Hello @erdemkahraman,
Welcome to the Toradex Community! Also, sorry for the delay in answering!
Could you please specify if you are using an image based on Downstream or Upstream Kernel? If you could send me the output of command tdx-info
from the module, it should give me all the necessary informaiton regarding your setup (detailed information here). On BSP 5.7, you should be able to get it as follows:
wget https://raw.githubusercontent.com/toradex/tdx-info/master/tdx-info --output-document=tdx-info && sh ./tdx-info --all

Hello @erdemkahraman,
I could build the dts files that you provided successfully for colibri-imx6
machine for BSP 5.7.2.
Here is the structure of my custom layer:
rudhi@nb:~/Yocto/ref_image_bsp5/oe-core/layers/meta-customer$ tree
.
βββ conf
β βββ layer.conf
βββ COPYING.MIT
βββ README
βββ recipes-kernel
βββ linux
βββ device-tree-overlays
β βββ colibri-imx6_gpio-keys_overlay.dts
βββ device-tree-overlays_%.bbappend
Here is the device-tree-overlays_%.bbappend
file:
FILESEXTRAPATHS:prepend := "${THISDIR}/${PN}:"
SRC_URI += "\
file://colibri-imx6_gpio-keys_overlay.dts \
"
TEZI_EXTERNAL_KERNEL_DEVICETREE += "\
colibri-imx6_gpio-keys_overlay.dtbo \
"
TEZI_EXTERNAL_KERNEL_DEVICETREE_BOOT = "\
colibri-imx6_gpio-keys_overlay.dtbo \
"
do_collect_overlays:prepend() {
cp ${WORKDIR}/colibri-imx6_gpio-keys_overlay.dts ${S}
}
After this, execute the bitbake
command to build compile the overlays:
MACHINE=colibri-imx6 bitbake device-tree-overlays
I could find the output dtbo
file here: build/deploy/images/colibri-imx6/overlays/colibri-imx6_gpio-keys_overlay.dtbo
Hello rudhi those are solved me thank you a lot
