    您好，休眠唤醒的实现方式如下
    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
    3 进入休眠

    Code: Select all

    echo mem > /sys/power/state
    4 添加唤醒源
    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>;
		};
	};
};
    5 触发唤醒源
    短接触发引脚和GND

    打印日志如下

    Code: Select all

    注意：该方法目前还存在问题休眠时会概率性出现EMMC错误只能通过重启唤醒，请谨慎使用

    你好，请问一下（luckfox-pico-ultra-w）这个开发板，第一步应该在那个文件中做出对应的添加，第四步：是不是在下面的在下面的文件中添加对应的代码
    ~/luckfox-pico/sysdrv/source/kernel/arch/arm/boot/dts/rv1106g-luckfox-pico-ultra-w.dts
    还有就是这种唤醒方式有办法设置成定时唤醒的方式吗，每隔多长时间从休眠中唤醒一下那种，我现在需要两种唤醒方式一个是使用引脚中断进行唤醒，第二种就是系统每隔多长时间自动唤醒一次。

    您好，使用luckfox-pico-ultra-w 对应的板级支持文件地址 为 <SDK>/project/cfg/BoardConfig_IPC/BoardConfig-EMMC-Buildroot-RV1106_Luckfox_Pico_Ultra_W-IPC.mk
    设备树文件对应sysdrv/source/kernel/arch/arm/boot/dts/rv1106g-luckfox-pico-ultra-w.dts，其中gpio-key是新节点需要直接添加到根节点中
    wifi 驱动也需要修改，需要在 <SDK>/sysdrv/drv_ko/wifi/aic8800dc/aic8800_bsp/Makefile 和 <SDK>/sysdrv/drv_ko/wifi/aic8800dc/aic8800_bsp/Makefile 添加

    Code: Select all

    ccflags-y += -DSDIO_REMOVEABLE
    目前RV1106 AOV的实现方案是有使用到定时器唤醒的，我们没有实际测试过，有需要可以参考文档

    我尝试了上面的步骤，现在可以成功的将当前的设备进入休眠模式，然后尝试对设备树进行修改，尝试在设备树中添加下面的代码作为休眠唤醒的触发源，想要使用gpio1—B0引脚作为唤醒触发源，但是使用下面的代码，经过测试之后并没有办法成功的编译
    屏幕截图 2025-02-18 161220.png

    Code: Select all

    {
	gpio-keys {
		compatible = "gpio-keys";
		autorepeat;
		pinctrl-names = "default";
		pinctrl-0 = <&pwr_key>;
		power-key {
			gpios = <&gpio1 RK_PB0 GPIO_ACTIVE_HIGH>;
			linux,code = <KEY_POWER>;
			label ="GPIO Key Power";
			debounce-interval = <100>;
			wakeup-source;
		};
	};
};

&pinctrl {
	buttons {
		pwr_key:pwr-key{
			rockchip,pins = <1 RK_PB0 RK_FUNC_GPIO &pcfg_pull_none>;
		};
	};
};
    下面是编译时出现的报错情况

    您好，建议另开新主题贴上修改后完整的dts 文件，目前从日志来看应该是dts配置出错了

    已经发布了，其实就是在dts文件中添加了上面的休眠唤醒引脚的设置代码，就导致报错出现的情况。
    还有就是上面的帖子中提到了有时候会在休眠的时候会出现emmc的报错情况，导致休眠出现问题，这时候除了重新上电才能唤醒开发板，还有其他办法去唤醒开发板吗。

    emmc报错属于内核奔溃只能重新上电或按reset按键重启开发板

    请问一下，当前的休眠不是主要是cpu的问题吗，为什么会出现emmc的报错，emmc不是存储设备吗？

    我没有深入研究过RV1106的休眠唤醒方案，只是在实际测试中小概率遇到，猜测进入休眠时设置的PMUIO外都掉电了，唤醒时EMMC的引脚重新上电初始化进入系统，有可能是上电时序异常导致没有成功初始化eMMC，而内核和文件系统都存放在eMMC中导致的奔溃，有需要可以自行测试了解
