RTC 测试所需的测试环境如下：
  • 硬件：开发板上安装有电池，用于给 RTC 供电
  • 软件：

    • PC 端的串口终端软件，用于 PC 和开发板进行串口通信

    • Linux 内核原生的 rtctest 工具

配置软件

在 Luban 的根目录下通过 make menuconfig 打开 rtctest：
Linux kernel
    Advance setting
        Linux Kernel Tools
            [*] selftests

rtctest 测试

  1. 进入rtctest 所在目录 /usr/lib/kselftests/rtc/
    cd /usr/lib/kselftests/rtc/

    rtctest 的主要功能是测试 RTC 的 Alarm 功能。

  2. 执行下列命令运行 rtctest：
    ./rtctest
    输出结果示例如下：
    TAP version 13
1..7
