Hi Nvidia:
Because we need to set timer which accuracy should be within one microsecond.
Linux timer can’t stratify our requirement.

Does TX2 support any hardware timer?
How can we use it in Linux kernel?

We see there are many timers in TX2. (TX2.png)
Do you have any sample code to use it in Linux kernel?

Hi dark.hou,

You could try to access /dev/rtc0 with public tool hwclock.
