https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1457370/am67-how-to-use-gpio-command-in-the-u-boot

器件型号：AM67

工具与软件：

大家好！

  我在 u-boot 已使用 GPIO 命令中使用了 am67 EVM。 如何确认 ？

与 EXP_GPIO0_38 (MCU_UART0_CTSN B5)相同、这是什么 ？

用法：
GPIO
-输入/设置/清除/切换指定的引脚

谢谢

    这些是在 U-Boot 中启用的 GPIO。 您要找哪一个？

    Keerthy、您好！

    我需要将 EXP_GPIO0_38 (MCU_UART0_CTSN B5)设置为1、这是什么 ？

    您好！

    您是否希望切换 MCU_UART0_CTSN？

    相应的 GPIO 编号为 MCU_GPIO0_7。

    GPIO@4201000_7：输入：0 []

    这是一个。
