Hi,
I’d like to know how can I change the fan mode.
I’ve found this commands in this forum (Jetson Nano Fanhttps://devtalk.nvidia.com/default/topic/1049521/jetson-nano/jetson-nano-fan/post/5326445/#5326445):
ON :
sudo sh -c 'echo 255 > /sys/devices/pwm-fan/target_pwm'
OFF :
sudo sh -c 'echo 0 > /sys/devices/pwm-fan/target_pwm'
But I’ve seen that checking the file /sys/bus/platform/devices/pwm-fan/pwm_rpm_table I get this table:
(Index, RPM, PWM, RRU, RRD)
(0, 0, 0, 40, 40)
(1, 1000, 80, 2, 2)
(2, 2000, 120, 1, 1)
(3, 3000, 160, 1, 1)
(4, 4000, 255, 1, 1)
(5, 5000, 255, 1, 1)
(6, 6000, 255, 1, 1)
(7, 7000, 255, 1, 1)
(8, 10000, 255, 1, 1)
(9, 11000, 255, 1, 1)
Then I doubt which real RPM will be set after typing the above command to pass 255 to /sys/devices/pwm-fan/target_pwm
How could I change the real RPM?
In addition, what do they mean RRU and RRD?
Thanks in advance
Jose
