Hi,

/ {
    aliases {
        /delete-property/ led2;
    };
    
};
/delete-node/ &led2;

This worked for me.

Hi,

I tried the suggested way to delete the node for LED, but getting the following error

FATAL ERROR: command exited with status 1: 'C:\ncs\toolchains\b620d30767\opt\bin\cmake.EXE' -DWEST_PYTHON=C:/ncs/toolchains/b620d30767/opt/bin/python.exe '-Bc:\Payal\Project\test\test_base_fw_logs_ble\test_base_fw\Code\build' -GNinja -DBOARD=nrf54l15dk/nrf54l15/cpuapp -DNCS_TOOLCHAIN_VERSION=NONE -DBOARD_ROOT=c:/payal/project/test/test_base_fw_logs_ble/test_base_fw/code '-SC:\ncs\v2.9.0\zephyr\share\sysbuild' '-DAPP_DIR:PATH=c:\Payal\Project\test\test_base_fw_logs_ble\test_base_fw\Code'

Hello,

You need to delete the LED (led2) node and aliases entirely in the devicetree. The error you are seeing occurs because the gpio-leds binding requires the gpios property for each LED node, and simply deleting the gpios property from led2 (or led_1 in your case) leaves the node incomplete, causing a Devicetree validation error.

Try the following way to delete the node for LED

/ {
    aliases {
        /delete-property/ led2;  // or led_1, depending on your alias naming
    };
    /delete-node/ &led2;        // or &led_1, depending on your node naming
};
