Hi, everybody. I’ve been working on optimize boot time on xavier nx with L4Tr35.3.1. And I found that after kernel boot, userspace took long time. with systemd-analyze, I disabled nvgetty.service and reduce about 6s in boot flow.
I wonder that will disabling nvgetty.service have any impact on normal use？or it is just a service to use the ttyTHS0

Hi 854053437,

Are you using the devkit or custom board for Xavier NX?

You would be fine to disable nvgetty.service since Xavier series is using combined UART (ttyTCU) to output the log.

I am using a custom board.

got it, thanks
