Jetson Nano Fan Temperature Trip

Hi everyone,

Small question about the Jetson Nano pwm fan. I’ve found documentation stating the fan stats spinning when the CPU/GPU reach an avg temperature of 51 degrees C. How can I change that value?

I’ve tried to look into /sys/devices/thermal-fan-est but most files are locked (even with sudo).

Anyone know how to change the trip temperature?

hello alexisguiter,

please refer to Thermal Zone session to have customization in the device tree.
you might also access L4T sources from download center, check below documentation for several examples to use device tree bindings.
for example,
$L4T_Sources/r32.4.2/Linux_for_Tegra/source/public/kernel/kernel-4.9/Documentation/devicetree/bindings/thermal/thermal.txt
