需要在uboot中配置默认GPIO，但不成功
1、设备树修改：
main_gpio0_pins_default:main-gpio0-default-pins {
bootph-all;
pinctrl-single,pins = <
AM62X_IOPAD(0x0118, PIN_OUTPUT_PULLUP, 7) /* GPIO0_69 GPIO_PHY_RSTn */
AM62X_IOPAD(0x0124, PIN_INPUT, 7) /* GPIO0_71 CPU_TMP_ALERT */
AM62X_IOPAD(0x0128, PIN_OUTPUT_PULLDOWN, 7) /* GPIO0_72 FEEDDOG */
AM62X_IOPAD(0x0030, PIN_OUTPUT_PULLUP, 7) /* GPIO0_12 GPIO_OSPI_RSTn */
AM62X_IOPAD(0x0038, PIN_OUTPUT_PULLDOWN, 7) /* GPIO0_14 SOC_FEEDEN */
>;
};
main_gpio1_pins_default:main-gpio1-default-pins {
bootph-all;
pinctrl-single,pins = <
AM62X_IOPAD(0x023C, PIN_INPUT, 7) /* GPIO1_47 PWR_MON_INT_1 */
AM62X_IOPAD(0x0240, PIN_INPUT, 7) /* GPIO1_48 PWR_MON_INT_2 */
AM62X_IOPAD(0x0244, PIN_OUTPUT_PULLUP, 7) /* GPIO1_49 VCC_3V3_RUN */
AM62X_IOPAD(0x01F0, PIN_OUTPUT_PULLUP, 7) /* GPIO1_30 GPIO_eMMC_RSTn */
>;
};
};
&main_gpio0 {
status = "okay";
bootph-all;
pinctrl-names = "default";
pinctrl-0 = <&main_gpio0_pins_default>;
};
&main_gpio1 {
status = "okay";
bootph-all;
pinctrl-names = "default";
pinctrl-0 = <&main_gpio1_pins_default>;
};
2、在uboot中，通过gpio status -a看，所有gpio引脚都是input，并没有变成output。
问题：我还需要配置什么，才能让gpio有默认输出状态呢
