ryuhj0915,

May I know which release are you using? I don’t hit such error when using nvpmodel with mode 0.

WayneWWW,

I’m using Jetpack4.2.2.

Do you have below node?
/sys/bus/platform/devices/pwm-fan/fan_profile

5

Yes, fan_profile file exists.

the content of the ‘fan_profile’ is “N/A”

6

Same here.

Can turn on/off the fan, but can’t change the fan profile to cool.

@gschimmel,

Please provide the release and hardware you are using. Do you hit the exact same error message as #1?

Hi there, thanks for your answer.

I’m on Jetson Xavier 16GB, Jetpack 4.3.

Same error here.

root@localhost:~# nvpmodel -m 0
NVPM ERROR: Error opening /sys/devices/platform/tegra-fuse/opt_tpc_disable: 2
NVPM ERROR: Error writing quiet to /sys/bus/platform/devices/pwm-fan/fan_profile: 22
NVPM ERROR: Fan failed to set mode:quiet
root@localhost:~#

Trying to write to /sys/devices didn’t work either.

Regards

Sorry for late reply. Do you only have one xavier? Just want to make sure whether this is a hardware problem or not.

Unfortunately, I have only one.

In the future I’ll have several to test.

If in the meantime is there anything I can try, please let me know.

thanks a lot
