RTC与ulog中的timestamp format for time冲突

发布于 2020-03-07 10:55:52 浏览：1279 订阅该版

最近在调试LPC1768 RTC，发现RTC驱动实现完成以后，只要开启ulog中的Enable timestamp format for time，启动就不行启动。
启动以后如下：
```
 \ | /
- RT -     Thread Operating System
 / | \     4.0.2 build Mar  7 2020
 2006 - 2019 Copyright by rt-thread team
```

进不了msh。

附上了drv_rtc.c的代码。
不知道是我哪里有问题，还请有经验的大神指教。
关闭该选项以后，进入系统，list_device如下：
```
msh />list_device
device                   type         ref count
---------------- -------------------- ----------
Filesystem       MTD Device           1       
MX25L128         Block Device         0       
spi10            SPI Device           0       
spi1             SPI Bus              0       
rtc              RTC                  1

uart1            Character Device     0       
uart0            Character Device     2       
msh />
```
