Can't run jetson_clocks.sh

Robotics & Edge Computing Jetson & Embedded Systems Jetson TX2

Hi,
I recently got a jetson TX2 developer kit, I installed OS and Cuda using jetpack 3.0, the board is working fine but when I try to run the jetson_clock.sh script I get “Can’t access Fan!” error.
Looking at the script I noticed that to start the fan it accesses the /sys/kernel/debug/tegra_fan folder. Navigating from terminal I then noticed that I don’t have such folder. I tried to reinstall everything using jetpack but this didn’t fix the problem.
How can I resolve this problem?

Thanks for help
Best regards

what if you try jetpack 3.1 or 3.2 instead of 3.0?

Are you running it with sudo ?

sudo /home/nvidia/jetson_clocks.sh
sudo ls /sys/kernel/debug/tegra_fan

I tried with 3.1 but still got the problem, then I tried with 3.2 and it fixed, now everything works fine

Thanks for helping me
