How to Modify the JEDEC ID

[SunHuang]

In version 2.9.0, I modified the JEDEC ID.

The system is supposed to send a "Deep power- down enter(0xB9)" command after reading the JEDEC ID.

However, after the system reads the JEDEC ID, there is no response at all.

I have already modified the values in the device tree.

Is there anything else I need to do? By the way, it worked normally in version 2.6.1.

&spi3
{
    compatible = "nordic,nrf-spim";
    status = "okay";
    cs-gpios = <&gpio0 18 GPIO_ACTIVE_LOW>;
    pinctrl-0 = <&spi3_default>;
    pinctrl-1 = <&spi3_sleep>;
    pinctrl-names = "default", "sleep";
    mx25r64: mx25r6435f@0
    {
        compatible = "jedec,spi-nor";
        status = "okay";
        reg = <0>;
        spi-max-frequency = <8000000>;
        label = "MX25R64";
        jedec-id = [20 00 16];
        sfdp-bfp =
        [
            53 46 44 50  08 01 00 FF  00 08 01 14  10 00 00 FF
            F5 20 C1 FF  FF FF FF 01  00 00 08 6B  08 3B 00 00
            EE FF FF FF  FF FF 00 00  FF FF 00 00  09 DB 0C 20
            10 D8 00 00  04 08 0C 00  90 F3 0E 00  00 00 00 80
        ];
        size = <67108864>;
        has-dpd;                                                                       // deep power
        t-enter-dpd = <10000>;
        t-exit-dpd = <35000>;
        wp-gpios = <&gpio0 15 (GPIO_ACTIVE_HIGH)>;
    };
};

Hello,

What does the log from the nRF say?

Would it be possible to zip and upload the application that is working in v2.6.1, and the one that is not working in v2.9.0?

For debugging purposes, does it work if you try to build without sysbuild in v2.9.0? You set this when you create your build configuration, by ticking off "no sysbuild" at the very bottom. Alternatively, if you are building from the command line, you can add the argument --no-sysbuild.

If this works, it suggests that there is some configuration setup that has changed, that needs some tweaking.

Best regards,

Edvin

Hi,

Thank you for your reply. I’ve found the cause. Although I didn’t enable QSPI, I still had to forcibly disable it.

Thank you for the update! It may be useful for other encountering similar issues!

Have a nice weekend!

Best regards,
