如何同步SPE和A核的时钟

orin nano上如在A核和SPE之间做时间同步?他们有共用的系统时钟吗?

Though I’ve not tried, I think you can try TSC, or TSCUS, which should be global across the Orin chip.

SPE开发手册里并没有关于TSC的描述,有相关参考吗。

TSC is just a module for time stamp counter.
You can take a look at Orin TRM for details.

You can also try tegra_tke_get_tsc64 and tegra_tke_get_usec. They may help.
