You can use systemd to do it.
Please refer to
https://devtalk.nvidia.com/default/topic/1000657/jetson-tx2/script-for-maximum-clockspeeds-and-performence/post/5241246/#5241246

please note that jetson_clocks is now placed in the PATH so we don’t need to specify absolute path but just “jetson_clocks”.

Hi,there.I have followed this,but it not worked.
On the AGX I created a startup service named jetsonClocks.service with the below lines of code in it and put it in etc/systemd/system folder:

[Unit]
Description=Maximize Jetson Performance
After=multi-user.target

[Service]
ExecStart=/bin/sh /home/sf/zqm/clocks.sh

[Install]
WantedBy=multi-user.target

In the clocks.sh file just put:

#!/bin/bash
# Maximize performance on the Jetson
# How long would this hold up in a long environment? No idea

sleep 6

jetson_clocks

exit 0

Then I run the following commands to enable the service

sudo chmod 644 /etc/systemd/system/jetsonClocks.service
sudo systemctl daemon-reload
sudo systemctl enable jetsonClocks.service
sudo reboot

But nothing happened.And I run

sudo clocks.sh

It worked that Maximize performance on the Jetson.

Not sure why but you can check the status of systemd by running

sudo systemctl status jetsonClocks.service

This worked fine for me

[Unit]
Description=Maximize Jetson Performance

[Service]
ExecStart=/usr/bin/jetson_clocks

[Install]
WantedBy=multi-user.target

Hi,there.I use your jetsonClocks.service file,and reboot my device.it doesn’t work,and the service status:

jetsonClocks.service - Maximize Jetson Performance
   Loaded: loaded (/etc/systemd/system/jetsonClocks.service; enabled; vendor preset: enabled)
   Active: inactive (dead) since Wed 2019-11-13 10:41:36 CST; 1min 7s ago

11月 13 10:41:35 sf-desktop systemd[1]: Starting Maximize Jetson Performance...
11月 13 10:41:36 sf-desktop systemd[1]: Started Maximize Jetson Performance.

after reboot,the jetson_clocks status:

And I try to modify nvpmodel.service:

[Unit]
Description=nvpmodel service
; Everything depends on the NVIDIA per-boot script
After=nv.service
Requires=nv.service
; TPC power gating must be enabled before anything touching gpu
Before=graphical.target
Before=gdm3.service lightdm.service

[Service]
Type=simple
##################ExecStart=/usr/sbin/nvpmodel -f /etc/nvpmodel.conf
ExecStart=/usr/bin/jetson_clocks

[Install]
WantedBy=multi-user.target

and reboot ,it worked.I am confused that.

You can also try the rc.local
