器件型号：SK-AM62A-LP工具/软件：
您好：
我按照 本教程 和 其他教程 尝试将 MCU_GPIO0_16 设置为电路板的唤醒源。
我已经按照第二个教程的建议修改了第 35 行的“k3-am62x-sk-lpm-wkup-sources.dtso"。“。 我注意到、还需要修改“wak_mcugpio1_pins_default"，“，这、这是我在第 63 行做的。 请参阅此处的文件：

我完全按照说明将此文件编译到.dtbo、并将其包含在设备树中、还按照规定修改了 uEnv.txt。
当我进入深度睡眠或仅 MCU 模式时、将引脚 (J8 MCU 接头上的引脚 11) 接地并不能唤醒器件（根据教程的建议）。 将引脚连接到 3.3V 也无法唤醒器件。
我知道、RTC 以及 WKUP_UART 都能够从深度睡眠中唤醒器件。
我还应该怎么做才能使用可在 J8 MCU 接头上访问的 MCU GPIO 唤醒器件？
