测试指南
准备测试环境
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
-
打开测试功能
在 Luban 的根目录下通过 make menuconfig 打开
rtctest：Linux kernel
Advance setting
Linux Kernel Tools
[*] selftestsrtctest 测试
-
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。 -
执行下列命令运行
rtctest：./rtctest输出结果示例如下：TAP version 13 1..7 # Starting 7 tests from 2 test cases. # RUN rtc.date_read ... # rtctest.c:49:date_read:Current RTC date/time is 05/01/1970 21:50:57. # OK rtc.date_read ok 1 rtc.date_read # RUN rtc.uie_read ... # OK rtc.uie_read ok 2 rtc.uie_read # RUN rtc.uie_select ... # OK rtc.uie_select ok 3 rtc.uie_select # RUN rtc.alarm_alm_set ... # rtctest.c:137:alarm_alm_set:Alarm time now set to 21:51:06. # rtctest.c:156:alarm_alm_set:data: 1a0 # OK rtc.alarm_alm_set ok 4 rtc.alarm_alm_set # RUN rtc.alarm_wkalm_set ... # rtctest.c:195:alarm_wkalm_set:Alarm time now set to 05/01/1970 21:51:09. # OK rtc.alarm_wkalm_set ok 5 rtc.alarm_wkalm_set # RUN rtc.alarm_alm_set_minute ... # rtctest.c:239:alarm_alm_set_minute:Alarm time now set to 21:52:00. # rtctest.c:258:alarm_alm_set_minute:data: 1a0 # OK rtc.alarm_alm_set_minute ok 6 rtc.alarm_alm_set_minute # RUN rtc.alarm_wkalm_set_minute ... # rtctest.c:297:alarm_wkalm_set_minute:Alarm time now set to 05/01/1970 21:53:00. # OK rtc.alarm_wkalm_set_minute ok 7 rtc.alarm_wkalm_set_minute # PASSED: 7 / 7 tests passed. # Totals: pass:7 fail:0 xfail:0 xpass:0 skip:0 error:0
