Any suggestions to my problem
Even under heavy load and with CPU / GPU temperatures in range on 70-80 degrees the Fan in my development kit is not starting. Not even with MAXN power mode.
I have forced the fan speed with jetson_clocks.sh to 255.
And after the forcing, the script with --show parameter reports “Fan: speed=255”.
sudo cat /sys/kernel/debug/tegra_fan/temp_control reports 1
sudo cat /sys/kernel/debug/tegra_fan/target_pwm reports 255
Sometimes by tapping or knocking the unit lightly fan rotates less than second and dies out.
Did I receive faulty unit?
