RV1106低功耗休眠与唤醒如何实现？
Posted: 2025-01-13 5:25
RV1106低功耗休眠与唤醒如何实现？有没有相关资料和帮助文档？
1 板级支持文件中的 RK_KERNEL_DEFCONFIG_FRAGMENT 属性添加 rv1106-pm.config
2 开启休眠唤醒打印（此步骤可省略）
Code: Select all
echo 1 > /sys/power/pm_print_times
Code: Select all
echo mem > /sys/power/state
设备树添加
Code: Select all
/ {
gpio-keys {
compatible = "gpio-keys";
autorepeat;
pinctrl-names = "default";
pinctrl-0 = <&pwr_key>;
power-key {
gpios = <&gpioX RK_PXX GPIO_ACTIVE_HIGH>;
linux,code = <KEY_POWER>;
label ="GPIO Key Power";
debounce-interval = <100>;
wakeup-source;
};
};
};
&pinctrl {
buttons {
pwr_key:pwr-key{
rockchip,pins = <X RK_PXX RK_FUNC_GPIO &pcfg_pull_none>;
};
};
};
短接触发引脚和GND
打印日志如下
