部件号：AM62P

工具/软件：

您好：

我的定制电路板上有 soc “AM62P"，“，我、我配置了一些 GPIO 引脚“GPIO1_2"，“，以、以报告按钮在按下 0v 时的状态、如果没有、应该为 1、8v。
可以看到、上述 PB 连接到 D19、我将其配置为 uboot 器件树的 PMX 节点中的输入。

        main_powerbutton_pins_default: main_powerbutton_pins_default {
                pinctrl-single,pins = <
                        AM62PX_IOPAD(0x0180, PIN_INPUT, 7) /* (D19) RGMII2_RXC.GPIO1_2 */
                >;
        };

我无法看到 GPIO 引脚的状态变化、并且我不确定在 uboot 中哪个引脚要实现目标？
我假设、它应该映射到 “GPIO@601000_2“、但 LLM 假设它应该为“GPIO@600000_34“、因为 GPIO 分为 32 引脚组。
