修改“u-boot”设备树中的电源后，使用\"STM32CubeProgrammer\"下载会一直重复下载，为什么？

我自己做的板子电源部分没有使用"stpmic"，而是使用分立式电源，我在移植OpenSTLinux（5.1.0）时遇到了问题，我修改“u-boot”设备树中的电源后使用"STM32CubeProgrammer"下载时会一直重复下载
我修改了这些位置：将"i2c4"下的"pmic: stpmic@33"节点全部删除，在根节点中添加了以下内容:
        vddcore: regulator-vddcore {
        compatible = "regulator-fixed";
                regulator-name = "vddcore";
                regulator-min-microvolt = <1200000>;
                regulator-max-microvolt = <1350000>;
                regulator-always-on;
        regulator-boot-on;
        };

    v3v3: regulator-3p3v {
        compatible = "regulator-fixed";
        regulator-name = "v3v3";
        regulator-min-microvolt = <3300000>;
        regulator-max-microvolt = <3300000>;
        regulator-always-on;
        regulator-boot-on;
    };

    v1v8_audio: regulator-v1v8-audio {
        compatible = "regulator-fixed";
        regulator-name = "v1v8_audio";
        regulator-min-microvolt = <1800000>;
        regulator-max-microvolt = <1800000>;
        regulator-always-on;
        regulator-boot-on;
    };

    vdd: regulator-vdd {
        compatible = "regulator-fixed";
        regulator-name = "vdd";
        regulator-min-microvolt = <3300000>;
        regulator-max-microvolt = <3300000>;
        regulator-always-on;
        regulator-boot-on;
    };

    vdd_usb: regulator-vdd-usb {
        compatible = "regulator-fixed";
        regulator-name = "vdd_usb";
        regulator-min-microvolt = <3300000>;
        regulator-max-microvolt = <3300000>;
        regulator-always-on;
        regulator-boot-on;
    };
