1.测评任务
测试M2354的硬件RTC，开启RTC功能，运用a href="https://bbs.elecfans.com/zhuti_emb_1.html" target="_blank">RT-Thread提供的bsp及库函数，实现一个RTC功能。
实现功能：初始化RTC时间，通过控制台每秒打印一次时间。
2.测评硬件
本次使用的硬件是Nuvoton官方的NuMaker-M2354开发板
mcu型号：M2354KJFAE
内核：cortex-M23
3.环境搭建及工程创建
在bsp->nuvoton->numaker-m2354 下应用env工具进行配置
4.下载运行
插入sd卡，复位后，控制台打印如下：

5.实验现象
microSD挂载失败，不知所以然，试了好多配置，留着之后再做研究，另外使用nuvoton的bsp里的例程，可以正确读取扇区，说明硬件没有问题的，另外看了论坛上有一个相同microSD任务的配置了就可以。看他git的工程没有上传成功。很诧异。
