Hi !
I don’t manage to apply my overlay to the device tree of my BeagleBone Black.
I followed carefully the instructions in u-boot-v2020.04/doc/README.fdt-overlays
In u-boot-v2020.04, I type
=> fdt apply $fdtovaddr
failed on fdt_overlay_apply(): FDT_ERR_NOTFOUND
but it doesn’t work.
Here is my overlay but it seems to be right :
/dts-v1/;
/plugin/;
/{
fragment@0 {
target = <&pcdev0>;
__overlay__ {
status = "disabled";
};
};
fragment@1 {
target = <&pcdev1>;
__overlay__ {
status = "disabled";
};
};
fragment@2 {
target = <&pcdev3>;
__overlay__ {
org,size = <1048>;
org,device-serial-num = "PCDEV4XXXXXX";
};
};
};
I don’t know what to do and don’t have a lot of experience in device trees unfortunately…
