jetson_clocks issue

I’m running jetson on custom carrier board:

root@localhost:~# jetson_clocks
/usr/bin/jetson_clocks: line 283: /sys/devices/17000000.gp10b/railgate_enable: Permission denied
/usr/bin/jetson_clocks: line 284: /sys/devices/17000000.gp10b/devfreq/17000000.gp10b/min_freq: No such file or directory
Error: Failed to max GPU frequency!
Can’t access Fan!

This board doesn’t have fan, because it is cooled externally.

Are these warnings serious? I want to put GPU frequency to maximum.

I’ve found reason: I haven’t plugged in nvgpu.ko
