想要通过使用tickcount让A核和M核做时钟同步，A核和M核是否具有各自的tickcount？
时钟同步是指时间同步吗？可以考虑用Linux上的RTC date/time来同步时间。
你好，需要做到毫秒级同步，AM6231这一款A核上没有RTC，外部RTC没办法做到这个程度吧
是的。请看下面的帖子是否有帮助。https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1214729/am6442-how-to-set-the-current-timestamp-in-application-and-real-time-core-s/4599245
好的，谢谢
