Hi, 

I am using a custom board based on nrf5340. I have an external QSPI flash that is different from the one defined by default dtsi file of nrf5340.

My overlay file throws no error if the default node and the alias are commented out from the actual nrf5340 board dtsi file

Default alias:

spi-flash0 = &mx25r64;

Default node:

&qspi {

    status = "";

    pinctrl-0 = <&qspi_default>;

    pinctrl-1 = <&qspi_sleep>;

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

    mx25r64: mx25r6435f@0 {

        compatible = "nordic,qspi-nor";

        reg = <0>;

        /* MX25R64 supports only pp and pp4io */

        writeoc = "pp4io";

        /* MX25R64 supports all readoc options */

        readoc = "read4io";

        sck-frequency = <8000000>;

        jedec-id = [c2 28 17];

        sfdp-bfp = [

            e5 20 f1 ff  ff ff ff 03  44 eb 08 6b  08 3b 04 bb

            ee ff ff ff  ff ff 00 ff  ff ff 00 ff  0c 20 0f 52

            10 d8 00 ff  23 72 f5 00  82 ed 04 cc  44 83 68 44

            30 b0 30 b0  f7 c4 d5 5c  00 be 29 ff  f0 d0 ff ff

        ];

        size = <67108864>;

        has-dpd;

        t-enter-dpd = <10000>;

        t-exit-dpd = <35000>;

    };

};

Custom overlay alias

qspi-flash0 = &en25qh64a;

overlay

&qspi {

    status = "okay";

    pinctrl-0 = <&qspi_default>;

    pinctrl-1 = <&qspi_sleep>;

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

    en25qh64a: en25qh64a@0 {

        compatible = "nordic,qspi-nor";

        reg = <0>;

        /* EN25QH64A supports pp and pp4io */

        writeoc = "pp4io";

        /* EN25QH64A supports all readoc options */

        readoc = "read4io";

        sck-frequency = <8000000>;

        jedec-id = [c2 28 17];

        // sfdp-bfp = [

        //     e5 20 f1 ff  ff ff ff 03  44 eb 08 6b  08 3b 04 bb

        //     ee ff ff ff  ff ff 00 ff  ff ff 00 ff  0c 20 0f 52

        //     10 d8 00 ff  23 72 f5 00  82 ed 04 cc  44 83 68 44

        //     30 b0 30 b0  f7 c4 d5 5c  00 be 29 ff  f0 d0 ff ff

        // ];

        size = <67108864>; /* 64 Mbit = 8 MB */

        has-dpd;

        t-enter-dpd = <10000>;  /* 10 µs in nanoseconds */

        t-exit-dpd = <30000>;   /* 30 µs in nanoseconds */

    };

};

If the default qspi is not commented out, I am getting undefined reference to `__device_dts_ord_133' error

If the default qpsi is commented out, the custom overlay and alias works with no error.

The whole point of an overlay file is that SDK need not be modified, but in my case i am modifying the SDK.


Am I missing out anything?

Thanks in advance

Also I wanted to add one more thing, 

In my application, I am only using the custom alias, qspi-flash0 = &en25qh64a;

static const struct device *const flash_dev = DEVICE_DT_GET(DT_ALIAS(qspi_flash0));

I am not calling the default qspi: spi-flash0 = &mx25r64;

Hello,

You can delete the existing mx25r64 node in your overlay using '/delete-node/ ' as shown below.

&qspi {
    status = "okay";
    pinctrl-0 = <&qspi_default>;
    pinctrl-1 = <&qspi_sleep>;
    pinctrl-names = "default", "sleep";
    /delete-node/ mx25r6435f@0;
    en25qh64a: en25qh64a@0 {
        compatible = "nordic,qspi-nor";
        reg = <0>;
        /* EN25QH64A supports pp and pp4io */
        writeoc = "pp4io";
        /* EN25QH64A supports all readoc options */
        readoc = "read4io";
        sck-frequency = <8000000>;
        jedec-id = [c2 28 17];
        // sfdp-bfp = [
        //     e5 20 f1 ff  ff ff ff 03  44 eb 08 6b  08 3b 04 bb
        //     ee ff ff ff  ff ff 00 ff  ff ff 00 ff  0c 20 0f 52
        //     10 d8 00 ff  23 72 f5 00  82 ed 04 cc  44 83 68 44
        //     30 b0 30 b0  f7 c4 d5 5c  00 be 29 ff  f0 d0 ff ff
        // ];
        size = <67108864>; /* 64 Mbit = 8 MB */
        has-dpd;
        t-enter-dpd = <10000>;  /* 10 µs in nanoseconds */
        t-exit-dpd = <30000>;   /* 30 µs in nanoseconds */
    };
};

Hi, 

I tried this but still I am getting the same error.

Hi,

Please verify if the mx25r6435f node got deleted in  the generated DT file for your app build (build/<name of your app>/zephyr/zephyr.dts).
