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?
请问你用的是什么硬件?Appro的参考设计还是TI的EVM,还是你自己的板子?
如果是Appro的参考设计请参考英文论坛讨论:e2e.ti.com/.../84972.aspx。
