So I try to change this value in DTB file “tegra124-jetson_tk1-pmic-pm375-0000-c00-00.dtsi” . But after rebooting, and measuring the voltage on J3A2 -pin 6 I still have 2.8V. Iven after booting my driver, value not changed.
as3722_ldo4: ldo4 {
regulator-name = "avdd-cam";
regulator-min-microvolt = <2800000>;
regulator-max-microvolt = <2800000>;
consumers {
c1 {
regulator-consumer-supply = "vdd_2v7_hv";
};
c2 {
regulator-consumer-supply = "avdd_cam2_cam";
};
c3 {
regulator-consumer-supply = "vana";
};
c5 {
regulator-consumer-supply = "vana";
regulator-consumer-device = "2-0018";
};
c6 {
regulator-consumer-supply = "vana";
regulator-consumer-device = "2-0036";
};
};
};
I change value from
regulator-min-microvolt = <2800000>;
regulator-max-microvolt = <2800000>;
to
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
Is that write am I doing, or I need change something else in others files to get LDO4 voltage value 3.3V ??
