Cannot restore default fan settings #39

Closed ViorelCN closed 5 years ago

ViorelCN commented 5 years ago

After using jtop, I cannot restore the default fan settings.

Before I used jtop, the fan came on automatically around 59C and shut off automatically around 43C. After using jtop, this I cannot restore the default settings to go back to this behavior.

Thanks

Hi @ViorelCN ,

Honestly I have the same issue on my board, when you set to "Auto" I set:

  1. /sys/devices/pwm-fan/temp_control = 1

technically "temp_control" enable the temperature control from linux, but I don't know why the fan doesn't wake up over a certain temperature. I finding a way to fix this issue, but it's strange.

Meanwhile you can restore to default following this order

  1. sudo service jetson_performance stop
  2. sudo bash -c 'echo "1" > /sys/devices/pwm-fan/temp_control'
  3. sudo bash -c 'echo "0" > /sys/devices/pwm-fan/target_pwm'
  4. sudo rm /opt/jetson_stats/fan_config (if you don't have this file is ok)
  5. sudo rm /opt/jetson_stats/l4t_dfs.conf (if you don't have this file is ok)

With the new version of jetson-stats, you can use:

sudo jtop --restore

And will restore all configurations from your jetson.

I temporary disable the option "Auto", I will update in a new version
