Hi,

You already have tickets open in regards to SPI NOR flash.

Duplicating tickets will not result in you getting your answer quicker, it will only increase the workload for us unnecessary.

I'm closing this,

regards

The following are c code to read JEDEC ID of NOR flash.

int flashNorInit(void) {

    const struct device *const dev = DEVICE_DT_GET(FLASH_NODE);

    if (!device_is_ready(dev)) {
        printk("%s: device not ready\n", dev->name);
        return 0;
    }

    printk("%s: device is ready\n", dev->name);


    uint8_t id[3];

    int ret = flash_read_jedec_id(dev, id);
    if (ret < 0) {
        printk("JEDEC ID read failed, %d\n", ret);
        return -1;
    }
    
    printk("jedec-id = [%02x %02x %02x];\n", id[0], id[1], id[2]);
}

Device node related to NOR flash is as follows.

&spi1 {
    compatible = "nordic,nrf-spim";
    status = "okay";

    cs-gpios = <&gpio0 11 GPIO_ACTIVE_LOW>;
    pinctrl-0 = <&spi1_default>;
    pinctrl-1 = <&spi1_sleep>;
    pinctrl-names = "default", "sleep";

    w25q256: w25q256jv@0 {
        compatible = "jedec,spi-nor";
        reg = <0>;
        spi-max-frequency = <8000000>;
        jedec-id = [ef 40 19];
        size = <0x10000000>;
        has-dpd;
        t-enter-dpd = <3500>;
        t-exit-dpd = <3500>;
    };
};
