Hello, everyone:
I used NX output PWM to fan, the same config as the original carrier board. tegra_pwm6 GPIO14(PH.01), but when i used the command cat /sys/kernel/debug/pwm, it show
may I know which JetPack release version you’re working with,
are you running heavy loaded program?
what’s the thermal condition, please also enable $ sudo tegrastats to gather processor reports.
besides, could you please refer to developer guide for Fan Speed Control.
thanks
fan is setting to full speed while system boot-up, it should behavior normally after you enter ubuntu desktop.
you may see-also Maximizing Jetson Nano or Jetson TX1 Performance, if you running jetson_clocks script to maximize Jetson Nano performance by adding --fan options. it’ll also set the maximum PWM fan speed.
