Change NCS SDK to 2.6.2 fix this issue.

&spi0 {
	status = "okay";
	pinctrl-0 = <&spi0_default>;
	pinctrl-names = "default";
	cs-gpios = <&gpio0 16 GPIO_ACTIVE_LOW>;
	p25q32h: p25q32h@0 {
		compatible = "jedec,spi-nor";
		reg = <0>;
		spi-max-frequency = <8000000>;
		label = "p25q32h";
		size = <0x2000000>;  // 32MB
		jedec-id = [85 60 16];
		status = "okay";

		partitions {
            compatible = "fixed-partitions";
            #address-cells = <1>;
            #size-cells = <1>;

            spi_storage_partition: partition@0 {
                label = "spi_storage";
                reg = <0x00000000 0x00400000>;
            };
        };
	};
};

[quote user="hugh512"]I got the same exception.[/quote]

If you are building for one of the Nordic boards then it would be better to use some other names than the ones that are already there. Try using for example 'custom_spi_default' instead of 'spi_default'.

Hi helsing: I got the same exception.

c:/ncs/toolchains/ce3b5ff664/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd.exe: zephyr/drivers/flash/libdrivers__flash.a(spi_nor.c.obj):(.rodata.spi_nor_0_config+0x0): undefined reference to `__device_dts_ord_84'

Below is the dts config

Thank you for giving it a try. I think we need to look for something else.

Which board are you building for? building for nrf52dk you will need to set both pinctrl names:

pinctrl-names = "default", "sleep";

Check zephyr\boards\nordic\nrf52dk\nrf52dk_nrf52832-pinctrl.dtsi for an example showing how to set both default and sleep.

It doesn't work, I put the code in main() function.according to the error, it has relation with libdrivers__flash & spi_nor

Hi Hugh,

Just letting you know I have started looking into this. My first guess is that something like below is missing from the main.c::main() function:

const struct device *flash_dev = DEVICE_DT_GET(DT_NODELABEL(p25q32h));

Please let me know if the above does not work, and I will look deeper into this tomorrow. Check out this in the meantime: Troubleshooting undefined reference to __device_dts_ord_<N>.
