DM365 RTC

下了一个MVL的DM365的内核,发现在内核启动阶段就有如下提示:

rtc_davinci_dm365 rtc_davinci_dm365.0: rtc intf: proc
rtc_davinci_dm365 rtc_davinci_dm365.0: rtc intf: dev (254:0)
rtc_davinci_dm365 rtc_davinci_dm365.0: rtc core: registered rtc_davinci_dm365 as rtc0

于是认为DM365应该有一个硬件RTC,在终端里输入hwclock命令,总是提示“hwclock: Could not access RTC: No such file or directory”

# hwclock -r
hwclock: Could not access RTC: No such file or directory
# hwclock -s
hwclock: Could not access RTC: No such file or directory
# hwclock -w
hwclock: Could not access RTC: No such file or directory
# hwclock -l
hwclock: Could not access RTC: No such file or directory

想请教一下TI的专家,DM365有硬件RTC么?

如果有的话,该怎么进行RTC的设定呢?
