Hi everyone,
I was playing the Jetson TX2 with ZED camera and running ROS Kinetic on Ubuntu 16.04.
I followed the instruction from ZED website (Getting Started with ROS and ZED | Stereolabs) to install the ROS package and device driver for ZED camera.
Issue:
After installing the ZED camera ROS wrapper, the fan on Jetson TX2 will drive up to maximum speed every time the Jetson TX2 is powered on.
Attempts:
1.
I tried the following command and it can calm down the fan for a while.
sudo ./jetson_clocks.sh
It is 0 in the /sys/kernel/debug/tegra_fan/target_pwm.
However, the fan will drive up to maximum speed after few seconds or minutes.
It is 255 again in the /sys/kernel/debug/tegra_fan/target_pwm.
I also tried to change the fan pwm manually by the following command
sudo gedit /sys/kernel/debug/tegra_fan/target_pwm
It is 255 in the /sys/kernel/debug/tegra_fan/target_pwm.
I replaced the 255 with 0 and saved it.
It is 0 in the /sys/kernel/debug/tegra_fan/target_pwm.
However, the fan will drive up to maximum speed after few seconds or minutes.
It is 255 again in the /sys/kernel/debug/tegra_fan/target_pwm.
Guess:
I guess there might be some background script is running to overwrite the sys/kernel/debug/tegra_fan/target_pwm with 255.
Have anyone encounter the same problem?
Any thoughts?
Thank you in advance,
Luke
