Fan control failed on xavier nx with jetpack 5.0.2

Hi Nvidia,
For factory requirement, we need test the fan on module, jp502 had changed the fan node

We test the Fan with command: echo 255 /sys/devices/platform/pwm-fan/hwmon/hwmon4/pwm1
But our module’s fan no start to turn, it looks this node could not control module fan.
And we can’t found the rpm node on /sys/devices/generic_pwm_tachometer/hwmon/hwmon/rpm
Does this node had implemented on jp502?

hello user8967,

please check hwmon nodes for rpm, for example, /sys/class/hwmon/hwmon1/rpm
you may also review all kernel enumerated nodes with… $ cat /sys/class/hwmon/hwmon*/name

please also check nvfancontrol. it is a userspace fan speed control daemon.
the default FAN_DEFAULT_PROFILE should be quite, can you update the profile as cool for testing?
